A member asked:

My toddler recieved influenza vaccine in february this year booster in march. does she need this years new influenza vaccine now?

A doctor has provided 1 answer

Yes: The vaccine she received in February was formulated to cover the strains that were predicted/seen for the Winter 2013-2014 season. This Winter 2014-2015 may have different strains present thus a completely different vaccine is formulated so receiving the new influenza vaccine is recommended.
