H1N1 vaccine ~ 2 shots better than one

[Guest guest]

This is a new study looking at B-cell malignancies and antibody protection by

H1N1 vaccines.

It was found that by day 21 post-vaccination, protective antibody titres of

were seen in 100% of controls compared to 39% of patients with B-cell

malignancies and 46% of allogeneic stem cell transplant recipients.

After a second dose, seroprotection rates increased to 68% in B-cell

malignancies and 73%, in patients with alloSCT .

These data demonstrate the efficacy of H1N1 vaccine in most patients with

haematological malignancies and support the recommendation for the

administration of 2 vaccine doses in immunocompromised patients. These results

may contribute towards the development of evidence-based guidelines for

influenza vaccination in such patients in the future.

PLEASE check with your doctor first before having a second shot...
