He besides expressed concerns astir the connection the proposal would nonstop to different countries wherever the usage of multi-dose flu vaccines is much common.

"That mightiness bounds the availability of the influenza vaccine for immoderate people," helium said during the gathering aft helium voted against restricting thimerosal flu vaccines.
