Seasonal flu vaccine safe and effective in young babies
The seasonal flu vaccine is safe and effective in infants as young as 6 to 12 weeks, according to a double-blind, randomized, placebo-controlled study in the February issue of the Pediatric Infectious Disease Journal. The study involved 1,375 infants. Half received two doses of trivalent inactivated influenza vaccine made by Sanofi Pasteur or placebo 1 month apart along with other childhood vaccines. Researchers found no safety outcome differences between the flu and placebo vaccines. Antibody responses to other childhood vaccines were similar in both groups. Increased antibody response to the three flu strains were seen in flu vaccine recipients, with the highest responses to influenza A strains. The investigators concluded that administering flu vaccine to young infants is safe and effective. Seasonal flu vaccines aren't currently licensed for babies younger than 6 months, and protecting them from flu has depended on immunizing their caregivers.
