I have no problem knowing existing vaccines for things like mumps, rubella, rheumatic fever, polio, tetanus, flu, shingl
shingles, etc.
These are proven vaccines and yes there are possible side effects but I'll take the odds of having a side effect vs getting polio or dying of lockjaw (tetanus)
And even the COVID vaccine was effective for certain people but the continual booster shot is ridiculous and I believe the hysteria the govt caused was close to criminal.
