MMR VACCINE

The most frequent reactions reported to occur

following MMR vaccine include brief burning and

stinging at the injection site; fatigue, sore

throat, cough, runny nose, headache, dizziness,

fever, rash, nausea, vomiting or diarrhea, and

sore lymph glands. Other reported reactions

include anaphylaxis, convulsions, encephalopathy,

otitis media, conjunctivitis, nerve deafness,

thrombocytopenia purpura, optic neuritis,

retinitis, arthritis, Guillain-Barre syndrome,

and subacute sclerosing panencephalitis.

In 1981, the British National Childhood

Encephalopathy Study concluded that there was a

statistically significant association between

measles vaccination and the onset of a serious

neurological disorder within 14 days of receiving

measles vaccine. The risk for previously normal

children was estimated to be 1 in 87,000 measles vaccinations.

In 1991, the Institute of Medicine concluded that

there is compelling scientific evidence that the

rubella vaccine portion of the MMR shot can cause

acute arthritis, with the highest incidence

occurring in adult women who receive rubella

vaccine (up to 15 percent) and that some

individuals go on to develop chronic arthritis.

Because either no studies or too few scientific

studies have ever been conducted to investigate

rubella vaccine reactions, a determination could

not be made as to whether rubella vaccine causes

other serious health problems which have been

reported following rubella vaccination including

thrombocytopenia purpura, radiculoneuritis

(spinal nerve pain) or other neuropathies such as carpal tunnel syndrome.

In 1994, the Institute of Medicine concluded that

there is compelling scientific evidence that the

measles vaccine can cause anaphylaxis that can

end in death and that the MMR vaccine can cause

thrombocytopenia (a decrease in the number of

platelets, the cells involved in blood clotting)

that can end in death. The incidence of

thrombocytopenia was estimated to be 1 case per

30,000 to 40,000 vaccinated children. The IOM

also concluded that the measles vaccine portion

of the MMR vaccine can cause vaccine-strain

measles virus infection that can end in death.

Because either no studies or too few studies have

ever been conducted to investigate MMR vaccine

reactions, a determination could not be made as

to whether measles or mumps vaccine causes

encephalitis or encephalopathy (brain disease);

sensorineural deafness, or insulin dependent

diabetes mellitus; whether the mumps vaccine

causes aseptic meningitis, orchitis (inflammation

of the testis) or sterility; or whether the

measles vaccine causes subacute sclerosing

panencephalitis, residual seizure disorders,

optic neuritis, transverse myelitis, or Guillain-Barre syndrome.

In 1995, a British study concluded that adults

who were vaccinated with measles vaccine as

children were at much higher risk of developing

inflammatory bowel disease such as Crohn's

disease and ulcerative colitis, as adults.

Several researchers are looking into the possible

link between inflammatory bowel disease and

measles vaccine as well as other vaccines.

The vaccine manufacturer's product insert for MMR

vaccine states " It is also not known whether [the

vaccine] can cause fetal harm when administered

to pregnant women or can affect reproduction

capacity " and " it is not known whether measles or

mumps vaccine virus is secreted in human milk.

Recent studies have shown that lactating

postpartum women immunized with live attenuated

rubella vaccine may secrete the virus in breast

milk and transmit it to breast-fed infants. "

An MMR vaccine manufacturer states that in a

study of 279 children 11 months to 7 years of

age, MMR vaccine was shown to be 95 to 99 percent

effective. Protection is estimated to persist for

up to 11 years. In a measles outbreak in the U.S.

in the late 1980's and early 1990's, it was found

that there were a significant number of vaccine

failures in older children, teenagers and adults,

when the disease can be more severe. The

government proceeded to recommend that a second

MMR shot be given to boost immunity either before

entrance to kindergarten or before entrance to junior high school.

In the national outbreak of measles during the

late 1980's and early 1990's, it also became

apparent that children who had been vaccinated

before 15 months of age were also at risk for

vaccine failure, especially if their mothers had

recovered naturally from measles disease as

children. An MMR vaccine manufacturer states

" Infants who are less than 15 months of age may

fail to respond to the measles component of the

vaccine due to presence in the circulation of

residual measles antibody of maternal origin, the

younger the infant, the lower the likelihood of

seroconversion. " The manufacturer goes on to

advise that infants vaccinated at less than 12

months of age will have to be revaccinated after

15 months of age even though " there is some

evidence to suggest that infants immunized at

less than one year of age may not develop

sustained antibody levels when later immunized. "

The measles outbreaks in the late 1980's and

early 1990's in the U.S. also demonstrated that

babies, whose young vaccinated mothers had never

naturally recovered from measles infection as

children, were vulnerable to measles infection

from birth. The young vaccinated mothers did not

have natural maternal antibodies to transfer to

their newborns to protect them from measles in

the first year of life. In the 1989-91 measles

outbreak in the U.S., the largest increase in

measles cases was in infants under one year old.

In 1995, there were 309 cases of measles reported

in the U.S. Out of 219 cases where vaccination

status was known, 123 (56 percent) had been

vaccinated with at least one dose. Of 285 measles

cases where age was known, 38 percent were under

5 years old and 39% were more than 20 years old.

In the mid-1990's, reports of an association

between autism and vaccination (specifically

suggesting a possible link with MMR vaccine) were

published. Although the U.S. Institute of

Medicine (IOM) acknowledged the hypothesis was

biologically plausible, IOM concluded there was

not enough evidence establishing a causal

relationship. Nevertheless, in light of

persistent reports by parents that their children

are regressing into autism after MMR vaccination,

there is an on-going scientific investigation by

independent scientific researchers, such as

British gastroenterologist Wakefield,

M.D., into clinical and laboratory evidence that

MMR vaccination may cause autism in biologically vulnerable children.

Objective. To determine if there is evidence for

a causal relationship between acute

encephalopathy followed by permanent brain injury

or death associated with the administration of

further attenuated measles vaccines (Attenuvax or

Lirugen, Hoechst n Roussel, Kansas City,

MO), mumps vaccine (Mumpsvax, Merck and Co, Inc,

West Point, PA), or rubella vaccines (Meruvax or

Meruvax II, Merck and Co, Inc, West Point, PA),

combined measles and rubella vaccine (M-R-Vax or

M-R-Vax II, Merck and Co, Inc, West Point, PA),

or combined measles, mumps, and rubella vaccine

(M-M-R or M-M-R II, Merck and Co, Inc, West

Point, PA), the lead author reviewed claims

submitted to the National Vaccine Injury Compensation Program.

Methods. The medical records of children who met

the inclusion criteria of receiving the first

dose of these vaccines between 1970 and 1993 and

who developed such an encephalopathy with no

determined cause within 15 days were identified and analyzed.

Results. A total of 48 children, ages 10 to 49

months, met the inclusion criteria after

receiving measles vaccine, alone or in

combination. Eight children died, and the

remainder had mental regression and retardation,

chronic seizures, motor and sensory deficits, and

movement disorders. The onset of neurologic signs

or symptoms occurred with a nonrandom,

statistically significant distribution of cases

on days 8 and 9. No cases were identified after

the administration of monovalent mumps or rubella vaccine.

Conclusions. This clustering suggests that a

causal relationship between measles vaccine and

encephalopathy may exist as a rare complication of measles immunization.

Key words: measles vaccine, encephalopathy, encephalitis.

Live attenuated measles vaccines used in the

United States have almost eliminated natural

measles and its complications.1 The Edmonston B

strain of live attenuated measles virus vaccine

induced fever >103°F in approximately one third

and a measles-like rash in approximately one half

of vaccine recipients.2 This vaccine, first

licensed for general use in the United States on

March 21, 1963, was simultaneously administered

with 0.02 mL/kg of human immunoglobulin that

greatly reduced the occurrence of fever and rash.

Further, or more attenuated, Edmonston-Enders

measles vaccines were developed to eliminate the

use of immunoglobulin. The Schwarz strain

(Lirugen) was licensed on February 2, 1965, and

used until 1976. Edmonston-Enders strain

(Attenuvax), licensed on November 26, 1968, was

combined with rubella vaccine (MR) or mumps and

rubella (MMR) and licensed on April 22, 1971. MMR

soon became the preferred immunization, and by

1976, Attenuvax became the only measles strain

distributed in the United States. On September

15, 1978, United States licensure of RA27/3

strain of MR replaced the HPV-77 (duck embryo)

strain licensed on June 9, 1969, and II was added to the trade names.

Postinfectious encephalopathy complicates

approximately 1 in 1000 cases of natural measles

and results in a mortality rate of 10% to 20% and

permanent central nervous system impairment in

the majority of survivors.3-6 Encephalopathy, in

this report, is defined as any significant

acquired abnormality of, injury to, or impairment

of function of the brain, with or without an

inflammatory response (ie, encephalitis,

encephalomyelitis). The onset of encephalopathy

usually occurs 2 to 7 days after the rash.

Pleocytosis is reported in approximately 20% of

these patients. The cause of this acute

monophasic encephalopathy that occurs in the

absence of a detectable virus in the brain is

obscure, but may be suggestive of an autoimmune

encephalopathy. This disease is distinct from

progressive subacute sclerosing panencephalitis

or subacute inclusion-body encephalitis in

immunodeficient patients caused by a persistent measles virus infection.7,8

Case reports and reviews suggest that similar

neurologic complications can, less frequently,

follow the administration of live attenuated

measles vaccine.9-11 In 1973, Landrigan and

Witte11 reviewed 84 patients with the onset of

neurologic disorders within 30 days after a live

measles vaccination who were reported to the

Centers for Disease Control and Prevention from

1963 to 1971. Encephalopathy (used

interchangeably with encephalitis) of

undetermined cause occurred 1 to 25 days after

vaccination in 59 patients, and of these, 45

patients had an onset 6 to 15 days after

vaccination. Long-term follow-up of 50 of the 59

patients revealed that 5 died, 19 had persistent

encephalopathy, and 26 had recovered fully. In a

study of the incidence of encephalitis in Olmsted

County, Minnesota, from 1950 to 1981 by Beghi et

al,12 78% of the patients recovered completely.

In the National Childhood Encephalopathy Study of

the United Kingdom from July 1, 1976 to June 30,

1979, Alderslade et al13 reported convulsions or

acute encephalopathy, without separating the two

conditions, in 17 children 7 to 14 days after

receiving the Schwarz strain measles vaccine, and

in 10 unvaccinated age-matched controls from the

local community. This study, designed to assess

serious neurologic disorders associated with

whole-cell pertussis vaccine, reported the onset

of encephalopathy <7 days after the administration of whole-cell pertussis.

The purpose of this study of claims submitted to

the National Vaccine Injury Compensation Program

is to determine whether or not there is evidence

for a causal relationship between the first dose

of a currently used attenuated measles vaccine,

MR, MMR, mumps, or rubella vaccine and

encephalopathy of undetermined cause with

permanent brain injury or death that occurred

within 15 days after administration.

STATUTORY FRAMEWORK

The National Childhood Vaccine Injury Act of 1986

established the compensation program, a federal

no-fault system that became effective on October

1, 1988, to provide compensation for individuals

who were injured or who died as a result of

specified immunizations.14 Claims of

encephalopathy, seizure disorder, or death after

the administration of covered vaccines, including

measles, mumps, or rubella, can be submitted to

the program and awarded compensation, if the

condition meets certain medical and legal

qualifications. For an individual who received a

measles, mumps, or rubella vaccine, the act

grants, in the Vaccine Injury Table, the

presumption of vaccine causation if the first

manifestation of encephalopathy occurs, in the

absence of an alternate cause, 15 days or less

after receiving any of these vaccines. The injury

or its residual effects, except when death

occurs, must persist for >6 months. The standard

of proof is a preponderance of the medical

evidence (ie, >50%, or more likely than not). In

addition, a vaccine cause may be demonstrated in

the absence of a Vaccine Table Injury, but

legally, this is a more difficult process for the

person seeking compensation. Effective March 10,

1995, the program changed the time period of a

Vaccine Table Injury for these vaccines and the

onset of encephalopathy from <15 days to 5 to 15 days.15

In 1994, an Institute of Medicine Committee

published a scientific review of clinical studies

and case series and reports of encephalopathy

after the administration of measles, MR, MMR, and

mumps vaccine.9 Their review identified no

conclusive evidence of the occurrence of

encephalopathy or encephalitis after the

administration of measles or mumps vaccine.

Nevertheless, the Institute of Medicine Committee

acknowledged biologic plausibility that measles

vaccine might cause encephalopathy. The lack of

controlled studies that distinguish background

rates of encephalopathy of undetermined cause in

unvaccinated populations makes a determination of causation difficult.

The medical records and affidavits in each

petition are reviewed by physicians in the

compensation program to determine, if possible,

the cause of the injury and to classify the

findings. The program's finding as to the onset

of neurologic signs or symptoms is based only on

the medical records. The diagnosis in each case

is based on the preponderance of the medical

evidence and the assessments of the treating

physicians. When deemed necessary, a medical

expert is obtained to review the case and provide

an expert opinion. All of the cases of

encephalopathy discussed in this article have

been reviewed in a consistent manner by the first author.

Children with appropriate development who

acquired an acute encephalopathy of undetermined

cause within 15 days after the administration of

the first dose of measles, MR, MMR, mumps, or

rubella vaccine between April 1970 and March 1993

followed by chronic encephalopathy or death were

selected for further analysis. The neurologic

criteria used for the diagnosis of acute

encephalopathy of undetermined cause were an

abrupt onset of neurologic symptoms and/or signs

with significant brain impairment including

behavior changes with a depressed level of

consciousness, ataxia, or seizures. Children

selected for this study had an acute

encephalopathic illness followed by chronic

encephalopathy including mental retardation,

seizure disorders, movement disorders, or motor or sensory disorders.

Cases of encephalopathy were excluded if an

infectious, toxic, traumatic, or metabolic cause

or a recent exposure to natural measles, mumps,

or rubella was identified or full recovery

occurred within 6 months. Seizures with mental

dysfunction attributed to the postictal state or

medication were not considered to be encephalopathy.

All children at the time of the vaccination were

considered by the authors to be susceptible to

the vaccines administered and >95% would be

expected to develop an immune response to the

vaccines. The evaluation of these children

reflects the standards and technical advancements

for diagnoses at the time of the injury. In a few

instances, attempts to isolate virus from

cerebral tissue and cerebrospinal fluid were

unsuccessful. Viral isolation and antibody

studies for arboviruses, enteroviruses, and

herpesvirus were negative on all children evaluated.

Identified patients were categorized with the

variables of sex, vaccine or vaccines

administered, age at vaccination, postvaccination

day of onset, neurologic symptom at onset, level

of consciousness or behavior changes during the

day of onset, fever, measles-like rash,

cerebrospinal fluid analysis, developmental

regression during or after the acute illness,

hospitalization, antibody studies, and

manifestations of permanent brain injury or death.

A total of 403 claims of encephalopathy and/or

seizure disorder after measles, MR, MMR, mumps,

or rubella vaccination were identified during

this 23-year period. Of these claims, 48 (25

males and 23 females) met the inclusion criteria

and acquired an acute encephalopathy of

undetermined cause 2 to 15 days after receiving

measles vaccine, MR, or MMR. This acute

encephalopathy was followed by permanent brain

impairment or death. The patients ranged in age

from 10 months to 49 months, with a median age of

15 months and a mean age of 17.5 months. No case

of encephalopathy of undetermined cause within 15

days after the administration of monovalent mumps

or rubella vaccine was identified.

Either Attenuvax or Lirugen was administered to 4

children between 1970 and 1974, and Attenuvax was

administered to 4 children between 1977 and 1982.

One child received MR, and 30 children received

MMR. Of the remaining 9 children, 2 received MMR

and diphtheria, tetanus, pertussis vaccine (DTP),

2 received MMR and Haemophilus influenzae type b

vaccine (Hib), 4 received MMR, DTP, and oral

poliovirus vaccine (OPV), and 1 received MMR, DTP, OPV, and Hib.

The onset of these 48 cases of encephalopathy

(Fig 1) occurred 2 to 15 days after the

administration of a measles-containing vaccine.

All patients were apparently well during the

first 48 hours after the vaccination

(postimmunization days 0 and 1). The clustering

and peak onset of encephalopathy occurred in 17

patients on days 8 and 9. Of the 12 cases of

encephalopathy that occurred within 7 days after

vaccination, 10 received only MMR; 1 with an

onset on day 4 received MMR and Hib; and 1 with

an onset on day 5 received MMR and DTP.

The clinical features of acute and chronic

encephalopathy or death in these 48 patients

(Table 1) were classified into three groups based

on the initial finding of ataxia in 6, behavior

changes in 8, and seizures in 34. The onset of

neurologic findings varied in severity from

ataxia or behavior changes to prolonged seizures

or coma. Fever preceded the onset of acute

encephalopathy by several hours to several days

in 43 of 48 children. A measles-like rash with a

postvaccination onset from day 6 to 15 occurred in 13 children.

TABLE 1

Clinical Findings of Acute Encephalopathy Among

48 Patients 2-15 Days After the First Dose of a

Further Attentuated Measles Vaccine, MR, or MMR, 1970-1993, and Sequelae

All children with acute ataxia had significant

behavior changes, and 3 of the 6 were

hospitalized. Neurologic sequelae in the ataxia

group included mental retardation in 3, seizure

disorder in 1, chronic ataxia in 4, and sensorineural hearing loss in 1.

A case example of this group is a normal

16-month-old female who received MMR, and 9 days

later, she had a fever, a measles-like rash, and

ataxia. Neurologic examinations revealed

unsteadiness and truncal titubation, nystagmus,

dysmetria, developmental regression, and

pleocytosis with 41 monocytes, and a normal brain

scan with magnetic resonance imaging. She was

diagnosed as having brainstem encephalitis. At

age 10 years, she had global developmental delay and cerebellar dysfunction.

The 8 children with initial behavior changes

rapidly progressed to coma. Two died during the

acute illness with autopsy findings of massive

cerebral edema and herniation. Of the 6

survivors, 6 had mental retardation, 5 spastic

paresis, 1 seizure disorder, 1 choreoathetosis,

and 1 died 6 years after the acute illness.

A case example of this group is a normal

29-month-old male who received MMR and Hib, and

14 days later, he developed fever, emesis, and

progressive lethargy. The following day, he was

hospitalized in coma with pleocytosis (246

monocytes, 54 lymphocytes), an elevated

cerebrospinal fluid (CSF) protein (49), negative

CSF bacterial and viral cultures, and an

electroencephalogram (EEG) with diffuse cerebral

slowing. He became rigid and opisthotonic.

Magnetic resonance imaging of the brain revealed

leukodystrophy. At age 5 years, he had hyperactivity and aggressive behavior.

In the 34 children with an onset of generalized

or focal seizures, coma and behavior changes

could not be attributed to a postictal state or

medication. These seizures, associated with fever

in 32 and a measles-like rash in 9, rapidly

progressed to coma in 29 and depressed or changed

consciousness in 5. Two apparently normal healthy

children received MMR vaccine and died 2 and 12

days later. Autopsy findings revealed cerebral

edema and uncal gyral herniation in one, and

viral encephalitis with hemorrhagic infarctions

of the thalamus and pons in the other. All

survivors had chronic encephalopathy with mental

retardation in 31, seizure disorder in 23, and

spastic paresis in 10. Three deaths occurred 3 months to 4 years later.

A case example of this group is a normal

16-month-old female who received measles vaccine,

and 7 days later, she developed a fever and a

measles-like rash. Ten days after the

vaccination, she was hospitalized with status

epilepticus, a temperature of 106°F, and a normal

CSF analysis. The following day, she had

intermittent seizures on anticonvulsant therapy,

coma, and left hemiparesis. An EEG showed totally

disorganized activity, epileptiform discharges,

and right hemisphere suppression. At age 10

years, she had spastic left hemiparesis and cognitive difficulties.

CSF analyses performed on 40 of the 48 children

were abnormal in 16. Pleocytosis, mainly

mononuclear cells, ranged from 7 to 246 cells in

11 patients, with an elevated protein of 49 mg to

101 mg in 4 of these 11. Four patients had only

an elevated CSF protein of 117 to 172 mg/dL and 1

had an elevated CSF pressure of 320 mm H2O

without further CSF analyses recorded.

The 48 patients (Table 2) are divided into three

time periods based on an onset day of 1 to 5, 6

to 10, and 11 to 15. The onset of ataxia,

behavior changes, seizures, and CSF pleocytosis

occurred in each time period, with approximately

one half of the cases in the 6 to 10 day time

period. The acute illness was associated with

fever in all but 5 patients; 3 of the afebrile

children were in the 1 to 5 day time period.

Clinical Findings in 48 Patients Through

Postvaccination Day 15 by Type of Neurologic Onset in 5-Day Period Groups

The distribution of encephalopathy by month of

onset (Fig 2) is random throughout the year with

a variation of 10 to 13 cases by season. By year

of onset, the number of cases ranged from 0 to 4

each year with a total of 15 in the 1970s, 1 to 5

with a total of 21 in the 1980s, and 1 to 6 with

a total of 12 in the 1990s with a peak in 1989

and 1990 and no trend in the pattern throughout

the years. The medical evaluations reflected the

standards of each time period. Prevaccination

clinical records revealed no evidence of hypersensitivity.

after the administration of the first dose of

MMR, MR, or further attenuated measles vaccine in 48 children (1970-1993).

Statistical Analysis

A statistical analysis was performed on the

distribution of the 48 cases that met the

inclusion criteria. A random distribution would

show the onset of 3.0 cases/day (48 div 16). The

denominator of 16 is used because the inclusion

criterion within 15 days includes 16 periods of

24 hours when the day of immunization is counted

as day 0. A comparison of the observed number to

the expected number per day was performed based

on the use of a standardized morbidity ratio. The

distribution was nonrandom with clustering and 2

statistically significant increases (0.01 < P <

..05) of 9 and 8 cases on postvaccination days 8

and 9, respectively.16 Our analysis found no

significant difference between the onset of

encephalopathy and age or sex. In the absence of

any obvious bias and confounding, this finding is

evidence for a causal relationship between

further attenuated measles vaccine, alone or in

combination, and acute encephalopathy of

undetermined cause followed by permanent brain impairment or death.

Abstract

Manifestations of acute encephalopathy including

loss of consciousness, ataxia, seizures, and

pleocytosis among these 48 children is similar to

the clinical features of acute encephalopathy

described after natural measles and other live

measles vaccines.1,2,4,8,10 The earlier onset of

these cases of encephalopathy after the injection

of live attenuated measles vaccine as compared

with the onset after natural respiratory exposure

to wild-type measles virus may be related to the

route of entry, as is the earlier onset of

measles-like symptoms and immune responses.17

Whether the onset of encephalopathy within 5 days

after a measles vaccination can be caused by

vaccine virus replication and immune responses is not clear.

Encephalopathy after natural measles is known to

occur in young children, and in some, there is

full recovery. Among children in England and

Wales, et al6 reported 389 cases of

encephalitis after natural measles with 11% of

these cases at age 1 to 2 years and 13% at 3 to 4

years. It is biologically plausible that

encephalopathy with variable outcomes could occur

after measles vaccine administered to children of the same age.

A comparison of these cases to claims seeking

compensation could be biased, but there is no

evidence for bias in the recording of the onset

of acute encephalopathy in the medical records or

the selection of cases analyzed. Study of this

issue is hampered by a lack of background

encephalopathic rates in unvaccinated children. A

review of similar cases reported to other systems could be helpful.

Claims with an onset of acute encephalopathy of

undetermined cause within 15 days after a

measles, MR, MMR, mumps, or rubella vaccination

between 1970 and 1993 followed by permanent brain

injury or death have an equal likelihood of being

recommended for compensation by the program

physicians regardless of whether the injury began

on day 0 or day 15. If the null hypothesis is

true and the measles, mumps, or rubella vaccine

has no causal relationship to the acute

encephalopathy, the number of cases with an onset

of neurologic findings of encephalopathy each day

during this period would be expected to have a

random distribution with essentially equal

numbers of cases on each day. Our results of a

statistically significant cluster on days 8 and 9

after measles immunization indicates this may be

an effect of measles vaccine, MR, and MMR.

From 1970 to 1993 in the United States,

approximately 75 000 000 children received

measles vaccine by age 4 years based on 83 000

000 births and an immunization rate of 90%. The

48 cases of encephalopathy probably represent

underreporting to this passive system, which does

not require individuals to file for compensation

and requires medical documentation. However,

given the generous compensation offered in this

program, it is reasonable to conclude that most

serious cases temporally related to a vaccination

have been captured. In the absence of a specific

test to determine vaccine causation, these 48

cases may include some nonvaccine cases

representing background rates. Nevertheless, with

a denominator of 75 000 000 vaccinees throughout

23 years, the incidence of acute encephalopathy

caused by measles vaccine in this cohort can

reasonably be described as very low.

The Controversy of the Latent Period Following Immunizations

Harold E Buttram, MD

September 21, 2001

Introduction:

In 1986 the U.S. Congress passed the National

Childhood Vaccine Injury Act, which set up a

system whereby the families of vaccine-injured

children could be compensated for such injuries.

Based on personal experience and observation,

there has been much criticism of this system and

question whether not it is serving its intended

purpose. (1) One of the major areas of

controversy surrounding the act involves its

limitations in the latent periods, whereby

certain defined reactions following vaccines must

be identified within a certain time period to

qualify for compensation by the childhood vaccine

injury act. For the complication of encephalitis,

the time limitation for the DTP or DTaP vaccine

is 3 days; for the measles-mumps-rubella (MMR) vaccine it is 5 to 15 days.

The limitations in latent periods following

vaccines have been generally accepted by our

medical-legal system as guidelines in other areas

as well. Prominent among these is the " shaken

baby syndrome " (SBS) in which a parent or

caretaker is accused of injuring or murdering an

infant by violent shaking and causing a triad of

findings now commonly accepted as diagnostic of

SBS: retinal hemorrhages, subdural hematomas, and diffuse axonal injury. (2-5)

However, it has been observed that many cases

attributed to the SBS have occurred in a

time-related fashion following routine childhood

vaccines, especially in compromised children that

had been born from medically complicated

pregnancies. (6) Consequently there are valid

reasons for questioning whether or not some or

many cases that have been accused of SBS were not

the result of mistaken diagnoses, the true causes

of death or injury of the child having been vaccines.

Since questions surrounding the latent period

play a prominent role in many of these cases, it

is timely and appropriate to review the background of this issue.

Are Current Guidelines in the Latent Period Artifactual?

(A) The DTP (diphtheria-tetanus-pertussis) Vaccine:

If we think in terms of a vaccine-induced

encephalitis, most of the earlier literature

deals with the pertussis vaccine. Flexner (1930)

noted a strong tendency for the nervous system

manifestations to declare themselves between the

10th and 13th days. (7) In a review of 108 cases

recorded before 1929 by Gorter (1933) , the onset

of encephalitis was " strikingly constant, "

usually observed between the 10th and 12th days

following vaccination, commonly with a febrile

period on the 7th and 8th days, followed by

recovery until onset of the encephalitis. (8) In

1929 an editorial in the Journal of the American

Medical Association reported on an increase in

severe neurological complications following

infections and inoculations occurring on about

the 11th day after vaccines. (9) Over 50 years

later Munoz, (1984) in a mice study of

experimental encephalomyelitis elicited by

injection of pertussigen, found the same latent period of 11 to 13 days. (10)

In contrast, some of the literature since the

1970s has reported an entirely different pattern,

with the onset of encephalopathy largely falling

within a 3-day period following vaccines. (11-13)

We can only speculate as to the reasons for this

changing pattern. Perhaps it can be attributed to

the fact that, in those early years, children

were given very limited numbers of vaccines in

comparison with more recent years during which

they have routinely received the hepatitis B, H

influenza, and polio vaccines in addition to the

DTP, all given at the same time. The hepatitis B

vaccine has been implicated in neurological

disorders, autoimmune disorders, various forms of

vasculitis and cutaneous reactions, as well as

hemorrhagic complications. (See below, page 6)

Both the pertussis and H influenza vaccines have

been shown to have unusually high

hyper-sensitizing properties. (14) In many

vaccines thimerosal, which contains ethyl

mercury, has been added as a preservative. (In

some vaccines its use dates back to the 1930s.)

Thimerosal has also been found to have

sensitizing properties. (15) Consequently there

are valid reasons for believing that the

pertussis and H influenza vaccines, some of which

contain mercury, may be acting in a three-way

synergy in causing hypersensitivity reactions.

In the text, Vaccinations and Behavioral

Disorders, by Greg , the author made the

following comment in regards to the latent period:

" Today the latent period is rarely mentioned in

connection with neurological complications of

immunization. Contemporary studies on the

pertussis vaccine select an arbitrary time limit

in which reactions have to occur to be considered

as vaccine related. This time limit is usually 3 to 7 days.

" Perhaps the only study which explores the

dynamics of post DPT reactions is an independent

Australian study by Karlsson and Scheibner which,

with a monitor which followed breathing volumes,

found particular times of stress-induced

breathing following DPT injections. " (16) " Of

special importance (for stress) are days 2,5,6, and 8,11,13-16 and 18-21. (17)

By way of explanation, the above study involved

the use of a Cotwatch breathing monitor

controlled by a micro-processor and designed to

provoke alarms with breathing delays (apnea of

hypopnea with 5% or less of normal breathing

patterns) following DTP immunizations. It was

found in the study that these periods of stressed

breathing occurred in clusters of 15 minutes at a

time on the post-vaccine days listed above,

varying greatly from child to child. From our

point of view, the important feature of the study

is not so much the specific post-vaccine days on

which the stressed breathing occurred but the

fact that the clusters continued for 21 days

following the vaccines, (18) which would tend to

discredit the current medical-legal limitation for DPT reactions to 3 days.

Dr. Scheibner's findings do have some support in

a study which showed a fairly high incidence of

cardio-respiratory complications in premature

infants following vaccinations. (19)

Unfortunately, this study was of limited

duration. Another study throwing light on the

latent period is one coming from Japan, from

which it was found that increased histamine

sensitivity in mice, brought about by the

pertussis vaccine, showed two peaks, one on the

4th day following vaccination, and a second on

the 12th day. (20) In the same vein, in a letter

to the British Medical Journal, Rosemary Fox,

secretary of Parents of Vaccine Damaged Children, made the following comments:

" Two years ago we started to collect details from

parents of serious reactions suffered by their

children to immunizations of all kinds. In 65% of

the cases referred to us, reactions followed the

triple vaccine (diphtheria-pertussis-tetanus).

The children in this group total 182 to date; all

are severely brain damaged, some are also

paralyzed, and 5 have died. Approximately 60% of

reactions…occurred within 24 hours of

vaccination, 80% within 3 days, and all within 12 days. " (21)

It is important to point out in the above-survey

that 20% of reactions occurred beyond the current

3 day medical-legal limitation for the DPT vaccine.

Another important study throwing light on the

latent period involves an unpublished series of

25 cases with accusations or convictions of

parents or caretakers for the shaken baby

syndrome, a series collected by attorney Toni

Blake of San Diego, California (personal

communication, 2000) which have the following

features: 1) All occurred in fragile infants born

from complicated pregnancies. Problems included

prematurity, low birth weights, drug/alcohol

problems, diabetic mothers, or other maternal

complications. 2) All infants were 6 months age

or less. 3) Onset of signs and symptoms occurred

at about 2,4, or 6 months of age,WITHIN 12 DAYS

OF VACCINES, 4) All infants had subdural

hematomas. 5) Some had multiple fractures.

In addition to the work of Dr Viera Scheibner and

attorney Toni Blake, another enlightening area of

study for the latent period is the federal

Vaccine Adverse Events Reporting System (VAERS).

In her book, What Your Doctor May Not Tell You

About Children's Vaccinations, (22) Dr.

Cave makes the following observations about

VAERS: " It is common knowledge that less than 10%

of all adverse events following vaccinations are

reported to VAERS, which means that instead of

the 12,000 to 14,000 reports of hospitalizations,

injuries, and deaths made every year, there may

be as many as 120,000 to 140,000. "

Even a cursory examination of the VAERS database

for DTP/DTaP vaccines will reveal that the latent

periods for many vaccine reactions extend into

the 7 to 13 day periods, some extending beyond 14 days. (23)

No review of the latent period would be complete

without pointing out an almost insuperable

difficulty in getting dependable data on these

reactions due to the extreme reluctance of

doctors to report on vaccine reactions, a pattern

which has existed since the earliest days of

childhood vaccines. There are a number of reasons

for this. From their earliest years of training,

medical doctors have been taught to look upon

vaccines as one of the greatest achievements in

medical science, and any question about the

vaccines is often looked upon as disloyalty to

the profession. In addressing this issue in the

classic text, Shot in the Dark, by Coulter and

Fisher, the authors quoted an attorney

specializing in vaccine-damaged children. In

commenting on the deficiency in doctors'

reporting of vaccine reactions, the attorney

commented, " As is the case with many

pertussis-vaccine-injured children, none of the

treating physicians would commit themselves to a

final etiological diagnosis. It is strange that

parents of pertussis-vaccine-damaged children

often can only get an etiological diagnosis by

hiring an attorney and seeing one of the few

recognized experts in the U.S. on post-pertussis vaccine encephalopathy. " (25)

As a result of this physician-reluctance to

report vaccine reactions, large numbers of

reactions may be taking place beyond the

currently established time limits of the latent

period, unrecognized as to their true nature.

(B) The Hemophilus influenza (HiB) vaccine:

In one of the largest, if not the largest

randomized epidemiological trial ever conducted,

the effect of the Hemophilus vaccine on the

development of insulin dependent diabetes

mellitus (IDDM) was studied in Finland. (26) All

children born in Finland between October 1st,

1985 and August 31st, 1987, approximately

116,000, were randomized to receive 4 doses of

the HiB vaccine (PPR-D, Connaught) starting at 3

months of life or one dose starting at 24 months

of life. An intent to treat method was used to

calculate the incidence of IDDM in both treatment

groups until age 10. The incidence of IDDM was

also calculated in a control group of 128,500

children which did not receive the HiB vaccine.

(27) The results demonstrated a rise in IDDM

which was specific for the vaccinated cohort.

(28) However, the important point for our

purposes was that there was a consistent delay of

3.5 years between vaccination and onset of IDDM.

(It should be pointed out that IDDM is considered an autoimmune disease.)

At a presentation this past spring in Nashville,

Tennessee sponsored by the American College for

the Advancement of Medicine, (29) Dr.

Classen reviewed 32 publications in the medical

literature showing a similar increases in

diabetes mellitus in a number of countries with

the MMR and hepatitis B as well as the HiB

vaccine, again with latent periods up to three

years or more, according to graphs that were

provided. (Copies of references will be provided

on request). Rather than being specific to any

one vaccine, Dr. Classen offered his opinion that

the general immune stimulation from the vaccines

was the cause of a rise in autoimmunity. As an

interesting sidelight, Dr. Classen mentioned that

personnel in the U.S. navy are more heavily

immunized than their European counterparts, and

that the U.S. navy personnel have five times more

diabetes than their European counterparts.

© The MMR (measles-mumps-rubella) vaccine:

Whereas DTP and Hib vaccine-related

encephalopathy may be the result of interactions

between endotoxin and mercury, (the latter in the

form of the additive, thimerosal), the primary

mechanism of viral vaccines in causing

encephalopathy may be related to the propensity

of viruses (and viral vaccines) in bringing about autoimmune reactions. (30)

In order to provide an overview of the latent

period, there are two basic classes of immune

systems, the humoral or antibody producing

system, which tends to produce immediate-type

reactions, and cellular immunity, in which

reactions are delayed. Either class is capable of

producing autoimmunity. (31) Obviously, the usual

15 day limitation for the MMR vaccine excludes a

recognition of the delayed-type autoimmune

reactions and, by inference, even denies their

existence. In an article by Cohen and Shoenfeld

dealing with questions of vaccine-induced

autoimmunity, the authors pointed out that it is

a subject about which relatively little is known,

due to the paucity of clinical and laboratory

studies. (32) In point of fact a more recent

review on this subject cites a temporal

relationship of 2 to 3 months between vaccines and autoimmune reactions. (33)

Recently the subject of the latent periods for

the MMR vaccine came sharply into focus in an

article published in Adverse Drug Reaction &

Toxicology Review, (34) in which researchers

Wakefield and Montgomery, who have

been investigating a possible causal relationship

between the MMR vaccine and the

autism-enterocolitis syndrome, carefully reviewed

deficiencies in the early pre-licensing trials of

the MMR vaccine. In the article they pointed out

that follow up periods following the vaccine were

a maximum of 28 days and in some studies even

shorter periods. They stressed that such short

periods of observations following the vaccine

were totally inadequate to detect delayed

reactions, including pervasive developmental

delay (autism), immune deficiencies, and

inflammatory bowel disease, which are known from

earlier published reports to occur following both

the natural measles infection and the measles vaccine.

The most interesting feature of the

Wakefield/Montgomery article was that it was

reviewed by four leading British authorities, all

of whom had previously held positions in the

regulation and licensing of medicines in the

United Kingdom. (35) Taken as a whole, the

reviewers were supportive of the article, three

highly so. Fletcher, formerly a senior

professional medical officer for the Department

of Health wrote, " being extremely generous,

evidence of safety (of the MMR vaccine) was very

thin. " Noting that single vaccines for measles,

mumps, and rubella already existed, he argued,

" caution should have ruled the day " granting of a

product license was definitely premature. "

Professor Duncan Vere, former member of the

Committee on the Safety of Medicines, agreed that

the periods for tests were too short. " In almost

every case, " he wrote, " observation periods were

too short to include the onset of delayed

neurological or other adverse events. "

(D) The Hepatitis B vaccine:

Other than the references provided by

Classen, M.D. on the findings of increased

diabetes from the hepatitis B vaccine with a

latent period of 3 years, I am not aware of

additional information bearing on the latent

periods between hepatitis B vaccine and other

forms of reactions, which reflects the sheer lack of data on the subject.

However, many reactions to hepatitis B vaccine

may be taking place unrecognized, for two

reasons: Reason one, I have in my possession a

list of 109 references of published articles

reporting on complications from the hepatitis B

vaccine including autoimmune disorders,

neurological disorders, vasculitis and cutaneous

reactions. This list will be provided on request.

For reason two, in 1994 a special committee of

the national Academy of Sciences (Institute of

Medicine) published a comprehensive review of the

safety of the hepatitis B vaccine. When the

committee, which carries the responsibility for

determining the safety of vaccines by

Congressional mandate, investigated five possible

and plausible adverse effects, they were unable

to come to conclusion for four of them because

they found that relevant safety research had not

been done. Furthermore, they found that serious

" gaps and limitations " exist in both the

knowledge and infrastructure needed to study

vaccine adverse events. Among the 76 types of

vaccine adverse events reviewed by the IOM, the

basic scientific evidence was inadequate to

assess definitive vaccine causality for 50 (66%).

The IOM also noted that " if research(is) not

improved, future reviews of vaccine safety will

be similarly handicapped " . (36) For this reason,

the published reports of hepatitis B vaccine

reactions may only be a small portion of those

actually taking place, with large numbers of

delayed reactions taking place unrecognized.

Conclusion:

Based on published evidence that many vaccine

reactions take place beyond current medical-legal

time limits that have been established for

vaccines, and on overwhelming evidence that large

numbers of delayed vaccine reactions may be

taking place unrecognized, there are grounds for

believing that these time limitations may be unrealistic and artifactual.
