And given the fact that the vaccine schedule for these kids today has SO many more shots on it than even 20 years ago, those kids’ immune systems are hammered.
And don’t forget the doctors who are out there talking about how this is not the way to go about ramping up antibodies, by bypassing the skins’ defenses and such, but injecting this directly into the body. Plus combining three vaccines in one shot (MMR) that a lot of kids have real problems with. There’s nothing natural about the exposure when it’s injected. It bypasses normal defense mechanisms.
The only vaccines I’d take nowadays are for tetanus and rabies. Any of them used on an emergency basis.
