Attenuvax is a sterile lyophilized preparation of a more attenuated line of measles virus derived from Enders' attenuated Edmonston strain. The further modification of the virus in Attenuvax was achieved in the Merck Institute for Therapeutic Research by multiple passage of Edmonston strain virus in cell cultures of chick embryo at low temperature. The reconstituted vaccine is for subcutaneous administration. When reconstituted as directed, the dose for injection is 0.5 ml and contains not less than the equivalent of 1,000 TCID50 (tissue culture infectious doses) of the U.S. Reference Measles Virus. Each dose also contains approximately 25 mcg of neomycin. The product contains no preservative. Sorbitol and hydrolized gelatin are added as stabilizers. CLINICAL PHARMACOLOGY: Measles virus vaccine produces a modified measles infection in susceptible persons. Fever and rash may appear. Extensive clinical trials have demonstrated that measles virus vaccine is highly immunogenic and generally well tolerated.1-5 A single injection of the vaccine has been shown to induce measles hemagglutination-inhibiting (HI) antibodies in 97 percent or more of susceptible persons. Vaccine-induced antibody levels have been shown to persist for at least 13 years without substantial decline.6 Continued surveillance will be necessary to determine further duration of antibody persistence. INDICATIONS AND USAGE: Measles virus vaccine is indicated for immunization against measles (rubeola) in persons 15 months of age or older. A second dose of measles virus vaccine is recommended (see Revaccination ).7,8,9 Infants who are less than 15 months of age may fail to respond to 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. In geographically isolated or other relatively inaccessible populations for whom immunization programs are logistically difficult, and in population groups in which natural measles infection may occur in a significant proportion of infants before 15 months of age, it may be desirable to give the vaccine to infants at an earlier age. Infants vaccinated under these conditions at less than 12 months of age should be revaccinated after reaching 15 months of age. There is some evidence to suggest that infants immunized at less than one year of age may not develop sustained antibody levels when later reimmunized. The advantage of early protection must be weighed against the chance for failure to respond adequately on reimmunization.10,11 According to ACIP recommendations, most persons born in 1956 or earlier are likely to have been infected naturally and generally need not be considered susceptible. All children, adolescents, and adults born after 1956 are considered susceptible and should be vaccinated, if there are no contraindications. This includes persons who may be immune to measles but who lack adequate documentation of immunity as evidenced by: (1) physician-diagnosed measles, (2) laboratory evidence of measles immunity, or (3) adequate immunization with live measles vaccine on or after the first birthday.12 Measles virus vaccine given immediately after exposure to natural measles may provide some protection. If, however, the vaccine is given a few days before exposure, substantial protection may be provided. Individuals planning travel outside the United States, if not immune, can acquire measles, mumps or rubella and import these diseases to the United States. Therefore, prior to International travel, individuals known to be susceptible to one or more of these diseases can receive either a single antigen vaccine (measles, mumps or rubella), or a combined antigen vaccine as appropriate. However, M-M-R* II (Measles, Mumps, and Rubella Virus Vaccine Live) is preferred for persons likely to be susceptible to mumps and rubella; and if single-antigen measles vaccine is not readily available, travelers should receive M-M-R II (Measles, Mumps, and Rubella Virus Vaccine Live) regardless of their immune status to mumps or rubella.13,14,15 Revaccination: Children first vaccinated when younger than 12 months of age should be revaccinated at 15 months of age, particularly if vaccine was administered with immune serum globulin or measles immune globulin, a standardized globulin preparation. The American Academy of Pediatrics (AAP), the Immunization Practices Advisory Committee (ACIP), and some state and local health agencies have recommended guidelines for routine measles revaccination and to help control measles outbreaks.16,17* Vaccines available for revaccination include monovalent measles vaccine and polyvalent vaccines containing measles (e.g., M-M-R II (Measles, Mumps, and Rubella Virus Vaccine Live), M-R-VAX II (Measles and Rubella Virus Vaccine Live)). If the prevention of sporadic measles outbreaks is the sole objective, revaccination with a monovalent measles vaccine should be considered. If concern also exists about immune status regarding mumps or rubella, revaccination with appropriate monovalent or polyvalent vaccines should be considered after consulting the appropriate product circulars. Unnecessary doses of a vaccine are best avoided by ensuring that written documentation of vaccination is preserved and a copy given to each vaccinee's parent or guardian. Despite the risk of reactions (see ADVERSE REACTIONS), persons born since 1956 who have previously been given inactivated vaccine alone or followed by live vaccine within 3 months should be revaccinated with live vaccine to reduce the risk of the severe atypical form of natural measles that may occur.10,12 Use with other Vaccines: Routine administration of DTP (diphtheria, tetanus, pertussis) and/or OPV (oral poliovirus vaccine) concomitantly with measles, mumps and rubella vaccines is not recommended because there are insufficient data relating to the simultaneous administration of these antigens. However, the American Academy of Pediatrics has noted that in some circumstances, particularly when the patient may not return, some practitioners prefer to administer all these antigens on a single day. If done, separate sites and syringes should be used for DTP and measles virus vaccine.18 Measles virus vaccine should not be given less than one month before or after administration of other virus vaccines. CONTRAINDICATIONS: Do not give measles virus vaccine to pregnant females; the possible effects of the vaccine on fetal development are unknown at this time. If vaccination of postpubertal females is undertaken, pregnancy should be avoided for three months following vaccination (see PRECAUTIONS, Pregnancy ). Anaphylactic or anaphylactoid reactions to neomycin (each dose of reconstituted vaccine contains approximately 25 mcg of neomycin). History of anaphylactic or anaphylactoid reactions to eggs (see Hypersensitivity To Eggs). Any febrile respiratory illness or other active febrile infection. Active untreated tuberculosis. Patients receiving immunosuppressive therapy. This contraindication does not apply to patients who are receiving corticosteroids as replacement therapy, (e.g., for 's disease). Individuals with blood dyscrasias, leukemia, lymphomas of any type, or other malignant neoplasms affecting the bone marrow or lymphatic systems. Primary and acquired immunodeficiency states, including patients who are immunosuppressed in association with AIDS or other clinical manifestations of infection with human immunodeficiency viruses;19,20 cellular immune deficiencies; and hypogammaglobulinemic and dysgammaglobulinemic states. Individuals with a family history of congenital or hereditary immunodeficiency, until the immune competence of the potential vaccine recipient is demonstrated.21 *NOTE: A primary difference among these recommendations is the timing of revaccination: the ACIP recommends routine revaccination at entry into kindergarten or first grade, whereas the AAP recommends routine revaccination at entrance to middle school or junior high school. In addition, some public health jurisdictions mandate the age for revaccination. The complete text of applicable guidelines should be consulted.16,17 Hypersensitivity To Eggs Live measles vaccine is produced in chick embryo cell culture. Persons with a history of anaphylactic, anaphylactoid or other immediate reactions (e.g., hives, swelling of the mouth and throat, difficulty breathing, hypotension and shock) subsequent to egg ingestion should not be vaccinated. Evidence indicates that persons are not at increased risk if they have egg allergies that are not anaphylactic or anaphylactoid in nature. Such persons should be vaccinated in the usual manner. There is no evidence to indicate that persons with allergies to chickens or feathers are at increased risk of reaction to the vaccine.12 PRECAUTIONS: General Adequate treatment provisions including epinephrine, should be available for immediate use should an anaphylactic or anaphylactoid reaction occur. Due caution should be employed in administration of measles vaccine to persons with a history of cerebral injury, individual or family histories of convulsions, or of any other condition in which stress due to fever should be avoided. The physician should be alert to the temperature elevation which may occur following vaccination. (See ADVERSE REACTIONS.) Children and young adults who are known to be infected with human immunodeficiency viruses but without overt clinical manifestations of immunosuppression may be vaccinated; however, the vaccinees should be monitored closely for vaccine-preventable diseases because immunization may be less effective than for uninfected persons.19,20 Vaccination should be deferred for at least 3 months following blood or plasma transfusions, or administration of human immune serum globulin. There are no reports of transmission of live attenuated measles virus from vaccinees to susceptible contacts. It has been reported that attenuated measles virus vaccine live, may result in a temporary depression of tuberculin skin sensitivity.10 Therefore, if a tuberculin test is to be done, it should be administered either before or simultaneously with measles virus vaccine. Children under treatment for tuberculosis have not experienced exacerbation of the disease when immunized with live measles virus vaccine;22 no studies have been reported to date of the effect of measles virus vaccines on untreated tuberculous children. As for any vaccine, vaccination with measles virus vaccine may not result in seroconversion in 100% of susceptible persons given the vaccine. Pregnancy Category C Animal reproduction studies have not been conducted with measles virus vaccine. It is also not known whether measles virus vaccine can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Therefore, the vaccine should not be administered to pregnant females; furthermore, pregnancy should be avoided for three months following vaccination (see CONTRAINDICATIONS). Reports have indicated that contracting of natural measles during pregnancy enhances fetal risk. Increased rates of spontaneous abortion, stillbirth, congenital defects and prematurity have been observed subsequent to natural measles during pregnancy. There are no adequate studies of the attenuated (vaccine) strain of measles virus in pregnancy. However, it would be prudent to assume that the vaccine strain of virus is also, capable of inducing adverse fetal effects for up to three months following vaccination. Vaccine administration to postpubertal females entails a potential for inadvertent immunization during pregnancy. Theoretical risks involved should be weighed against the risks that measles poses to the unimmunized adolescent or adult. Advisory committees reviewing this matter have recommended vaccination of postpubertal females who are presumed to be susceptible to measles and not known to be pregnant. If a measles exposure occurs during pregnancy, one should consider the possibility of providing temporary passive immunity through the administration of immune globulin (human). Nursing Mothers It is not known whether measles vaccine virus is secreted in human milk. Therefore, because many drugs are excreted in human milk, caution should be exercised when measles virus vaccine is administered to a nursing woman. ADVERSE REACTIONS: Burning and/or stinging of short duration at the injection site have been reported. Anaphylaxis and anaphylactoid reactions have been reported. Occasional Moderate fever (101° - 102.9°F (38.3° - 39.4°C)) may occur during the month after vaccination. Generally, fever, rash, or both appear between the 5th and the 12th days. Cough and rhinitis have also been reported. Rash, when it occurs, is usually minimal, but rarely may be generalized. Erythema multiforme has also been reported rarely. Less Common High fever (over 103°F (39.4°C)). Mild lymphadenopathy has been reported. Rare Reactions at injection site. Allergic reactions such as wheal and flare at the injection site or urticaria have been reported. Diarrhea has been reported after vaccination with measles-containing vaccines. Children developing fever may, on rare occasions, exhibit febrile convulsions. Afebrile convulsions or seizures have occurred rarely following vaccination with live attenuated measles vaccine. Syncope, particularly at the time of mass vaccination, has been reported. Thrombocytopenia and purpura have occurred rarely. Vasculitis has been reported rarely. Forms of optic neuritis, including retrobulbar neuritis, papillitis, and retinitis may infrequently follow viral infections, and have been reported to occur 1 to 3 weeks following inoculation with some live virus vaccines. Experience from more than 80 million doses of all live measles vaccines given in the U.S. through 1975 indicates that significant central nervous system reactions such as encephalitis and encephalopathy occurring within 30 days after vaccination, have been temporally associated with measles vaccine very rarely.23 In no case has it been shown that reactions were actually caused by vaccine.24 The Center for Disease Control has pointed out that " a certain number of cases of encephalitis may be expected to occur in a large childhood population in a defined period of time even when no vaccines are administered " .25 However the data suggest the possibility that some of these cases may have been caused by measles vaccines. The risk of such serious neurological disorders following live measles virus vaccine administration remains far less than that for encephalitis and encephalopathy with natural measles (one per two thousand reported cases).26 There have been rare reports of ocular palsies, Guillain-Barre syndrome, or ataxia occurring after immunization with vaccines containing live attenuated measles virus. The ocular palsies have occurred approximately 3-24 days following vaccination. No definite causal relationship has been established between these events and vaccination. There have been reports of subacute sclerosing panencephalitis (SSPE) in children who did not have a history of natural measles but did receive measles vaccine. Some of these cases may have resulted from unrecognized measles in the first year of life or possibly from the measles vaccination. Based on estimated nationwide measles vaccine distribution, the association of SSPE cases to measles vaccination is about one case per million vaccine doses distributed. This is far less than the association with natural measles, 6-22 cases of SSPE per million cases of measles. The results of a retrospective case-controlled study conducted by the Center for Disease Control suggest that the overall effect of measles vaccine has been to protect against SSPE by preventing measles with its inherent higher risk of SSPE.27 Local reactions characterized by marked swelling, redness and vesiculation at the injection site of attenuated live virus measles vaccines, and systemic reactions including atypical measles, have occurred in persons who have previously received killed measles vaccine. Rarely, more severe reactions that require hospitalization, including prolonged high fevers, panniculitis, and extensive local reactions, have been reported.12,28 DOSAGE AND ADMINISTRATION: For Subcutaneous Administration Do not inject intravenously The dosage of vaccine is the same for all persons. Inject the total volume of the single dose vial (about 0.5 ml) or 0.5 ml of the multiple dose vial of reconstituted vaccine subcutaneously, preferably into the outer aspect of upper arm. Do not give immune globulin (IG) concurrently with measles virus vaccine. During shipment, to insure that there is no loss of potency, the vaccine must be maintained at a temperature of 10°C (50°F) or less. Before reconstitution, store measles virus vaccine at 2° - 8°C (36° - 46°F). Protect from light. Caution: A sterile syringe free of preservatives, antiseptics, and detergents should be used for each injection and/or reconstitution of the vaccine because these substances may inactivate the live virus vaccine. A 25 gauge, 5/8 " needle is recommended. To reconstitute, use only the diluent supplied, since it is free of preservatives or other antiviral substances which might inactivate the vaccine. Single Dose Vial: First withdraw the entire volume of diluent into the syringe to be used for reconstitution. Inject all the diluent in the syringe into the vial of lyophilized vaccine, and agitate to mix thoroughly. Withdraw the entire contents into a syringe and inject the total volume of restored vaccine subcutaneously. It is important to use a separate sterile syringe and needle for each individual patient to prevent transmission of hepatitis B and other infectious agents from one person to another. 10 Dose Vial (available Only To Government Agencies/Institutions) Withdraw the entire contents (7 ml) of the diluent vial into the sterile syringe to be used for reconstitution, and introduce into the 10 dose vial of lyophilized vaccine. Agitate to ensure thorough mixing. The outer labeling suggests " For Jet Injector or Syringe Use " . Use with separate sterile syringes is permitted for containers of 10 doses or less. The vaccine and diluent do not contain preservatives; therefore, the user must recognize the potential contamination hazards and exercise special precautions to protect the sterility and potency of the product. The use of aseptic techniques and proper storage prior to and after restoration of the vaccine and subsequent withdrawal of the individual doses is essential. Use 0.5 ml of the reconstituted vaccine for subcutaneous injection. It is important to use a separate sterile syringe and needle for each individual patient to prevent transmission of hepatitis B and other infectious agents from one person to another. 50 Dose Vial (Available Only To Government Agencies/Institutions) Withdraw the entire contents (30 ml) of diluent vial into the sterile syringe to be used for reconstitution and introduce into the 50 dose vial of lyophilized vaccine. Agitate to ensure thorough mixing. With full aseptic precautions, attach the vial to the sterilized multidose jet injector apparatus. Use 0.5 ml of the reconstituted vaccine for subcutaneous injection. Each dose of measles virus vaccine contains not less than 1,000 TCID50 (tissue culture infectious doses) of measles virus vaccine expressed in terms of the assigned titer of the U.S. Reference Measles Virus. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Measles virus vaccine, when reconstituted, is clear yellow. Storage It is recommended that the vaccine be used as soon as possible after reconstitution. Protect vaccine from light at all times, since such exposure may inactivate the virus. Store reconstituted vaccine in the vaccine vial in a dark place at 2° - 8°C (36° - 46°F) and discard if not used within 8 hours. REFERENCES: 1) Hilleman, M. R.; Buynak, E. B.; Weibel, R.
