The sars virus is about 80% the same as C19 and anyone with natural immunity to that virus is also immune to C19.
These variants of C19 are less than 1% changed yet these so called vaccines are useless already. Even initially they couldn't stop infection, only reduce the symptoms.
Now that so many have been given some protection from the effects of that initial virus form, instead of naturally becoming less virulent there's a real risk that it could increase it's virulence because it needs to increase the response to maintain conventional infection rates to survive.
We should have treated this with ivermectin so that people still got natural immunity and just got with life but that was never the plan and why ivermectin was effectively outlawed by the WHO.
