Each year flu shots are created to protect from what we think will be the most likely prevalent strains during the season. Some times they are right and some times they are way off. Either way there is some decision to try and target certain strains. They have also been tested for years and are not mRNA based.

Now, if Delta is the dominant strain of Batflu (which these vaccines are not designed for) how is pumping more of the same ineffective juice going to really help you?
