#Effective

I've gone to a site where medical studies can be posted and reviewed, etc. A researcher asked on June 8, 2020, if anyone had isolated, purified and demonstrated the SARS-CoV2 to be the cause of COVID-19. A couple of months later, the researcher said that none meet the scientific standard for proof. Then another researcher, who was doing the same thing, posted on Dec. 17, 2021, the SARS-CoV2 still was not isolated and purified. You can't tell me, that in over two years there's no SARS-CoV2 virus. To me, the things they are posting as the virus are nothing but the mutations from the shots and is what the dems counted on as their proof the virus exists. So how can a vaccine be effective against something that does not exist?
