Safety and efficacy of influenza vaccine in pregnancy

A recent randomised controlled trial of Trivalent Influenza vaccination of pregnant women have shown that the Flu Vax has 86% efficacy against protecting infants less than 8 weeks of age from Influenza; and 25-30 efficacy for protecting infants from Influenza between 8-24 weeks of age when this vaccine was compared with Placebo vaccination. This study is very encouraging and shows that the maternal Influenza vaccination provides passive protection from Influenza to the baby. The study also shows that the vaccine is of great benefit if the mothers’ have had Influenza vaccination during pregnancy especially the third trimester of pregnancy.
