100% true but if your're vaxed your immune system is mega compromised making something as trivial as a "variant" that would other wise pass for a head cold in un vaxed people could kill a vaxed person. Realize in animal trials when they re- infected the animals with the virus after being vaccinated (SARS in 2011) the animals could not handle it. They went into septic shock and died and that's why it's never been used in humans. We're seeing the last stage of the animal testing play out right now and it's only going to get much worse come fall and winter.
