Vaccines are not, or at least should not, be political.
A lot of misinformation about vaccines are most likely politically motivated and amplified and shared mostly by scared, uneducated people and a few who know better but think it's to their advantage.
While I agree with what Linus said, and I don't think I could have said it better, including the biology lesson, I highly doubt it will change anybody's opinion about vaccines.
The problem isn't a lack of information. It is a lack of understanding. It baffles me what ridicules easily disprovable, inconsistent drivel people believe. It's a failure in education, mostly people are taught what to think instead of how to think and how to evaluate information.
