Impossible!
We only need one vaccine ever, right?
Not a fresh vaccine for mutant strains, right?
Don’t be an idiot. There are well over twenty strains of flu, and each year the medical establishment picks 4 of them to make the quad valiant flu vaccine and 3 to make the standard vaccines this is normal practice for lipid virus that mutate in a regular basis. I’m so sick of people who don’t have at least a master’s of science running there mouths about stuff they are not even remotely qualified to speak on. Full disclosure I have two master’s and a PhD in sciences the lack of scientific prowess here sickens me.
Apologies for the English it’s not my native language.
