Or the vaccine experimental treatment caused it to mutate.
People exposed to SARS in 2003 have immunity to COVID-19 but people who took the experimental treatments don't?
Did the experimental treatment strip away the immunity they would have built since being exposed to COVID-19 in 2019?
It's possible, though not a given. It's similar to how cancer becomes resistant to chemo or bacteria become resistant to antibiotics. When you seal off one avenue they find another. A lot of people are complaining about the vaccine because it's not perfect.. but you realize it was an *emergency measure*. A new kind of plague had hit the world and was exploding everywhere and something needed to be done quickly to stem the tide. And the vaccine did great in practically ending the pandemic in the US.. until this new variant came along. Since you are opposed to the vaccine what do you think should have been done to stop the spread ?
