no they are not putting mRNA in the flu vaccine whoever told you that is a moron. pfizer is developing an mRNA flu vaccine but it’s nowhere near approval, this is the same egg-grown inactivated virus they’ve been using for decades.

the only thing that ever changes in the flu vaccine is the specific strains of virus they include. they can’t change any of the ingredients because otherwise they’d have to go through the entire multi-year regulatory process again.

ask yourself who benefits, I get the idea that the covid vaccines were rushed but it’s not like they’re gonna sell more flu vaccines because they put harmful chemicals in it or whatever. like if the whole system was really that dysfunctional they might as well just replace the shots with saline, what would be the point of going to all that trouble?
