What I do know is that, in reality, there is no such thing as “herd immunity”. It is only a lack of exposure. The diseases that are listed as “eradicated” still exist, and still pose a threat.
An uncountable bureaucrat DID mandate that I receive the childhood vaccine of smallpox. Thank God that my mother was in training to be a nurse and saw that my skin condition plus the vaccine would have likely resulted im my contracting small pox. It took notes from two doctors stating their approval to forgo the vaccine AND the threat of a lawsuit in order for the school to back off their position.
Herd immunity is a scientific medical fact. Research it. It’s not a theory.
