I guess I could understand why some people would be against the flu shot.
Even though it does not prevent the flu, due to mutating strains, the vaccine can inhibit, aka reduce your severity.
Honestly, that does not even compare to actual antivaxxers, who are against all vaccines, whether it be for measles, polio, whatever. They would rather not eradicate these infections, but plague them onto other people. Unacceptable!
Urgh, probably because they do not believe in eradication of diseases like smallpox, despite it being eliminated in the late 70's.
And sadly, some nut named Larry Cook is trying to put a stop to mandatory vaccination, which has been put into law in some states in the US
PROBABLY BECAUSE OF MEASLES OUTBREAKS THAT HAVE BEEN CAUSED DUE TO UNVACCINATED CHILDREN! Just saying.
Now more states, maybe even more countries are getting into this, which I understand why some people may not like it, well, blame the antivaxxers. Also, there is literally no reason not to vaccinate your kids! PLEASE GET THEM VACCINATED!
