Because it is free, and it has been a big nothing burger in causing adverse side effects, after 4 jabs for both me and my wife. I am at age 82, and wife is fighting stage-4 cancer for over 4 years now. If this vaccine could not hurt us even slightly, only conclusion I can draw is it is a big nothing burger for adverse effects.
I can also say that I have no proof this vaccine is really effective or not. But we have done 4 cruises since September 2021, and I have done 100+ visits to stores and medical offices, and both of us never got infected with the China virus. Wa sit the vaccine or just being cautious with social distancing or just luck of the Irish (my wife is mostly Irish) I do not know.
I haven’t taken one fake vax and no covid. You down don’t know what those shots can do to you down the road. If you had taken 3 shots and no covid, why keep taking them? People are dying from them so there are many adverse effects all over the world.
