WASHINGTON (AP) - Next year's flu vaccine is getting a complete overhaul to provide protection against three new and different influenza strains — hopefully better protection than this year's version.
Advisers to the Food and Drug Administration unanimously backed the new recipe on Thursday, echoing an earlier decision by the World Health Organization. It's a highly unusual move: Seldom are more than one or two strains swapped out from one year to the next.
Now the question is whether vaccine manufacturers can make such a big change in time to produce more than 100 million doses by the fall.
