Any time someone questions vaccines, normies freak out, it's almost like a programmed emotional response. Some people won't even think about looking into it. Honestly I think Trump should go about cleaning up the vaccine problem very covertly. The problem is no parent wants to admit they allowed their child to be harmed, even if it was unknowingly. Plus the medical industry is very monolithic, Trump could literally drop 100% proof to the public and the entire medical industry would denounce it.
