Dude, I was in the cab of a truck for 8 hours with a guy who it turns out had it. First strain. Then I took care of my elderly parents who both had it. I never got it. I also had not taking any vaccine. Claiming the vaccine worked because you didn't get covid is exactly like saying smoking wards off lung cancer because you smoke two packs a day and never got cancer.
One more thing about the vaccine. Much later, I believe the end of 2021, while idiots everywhere were masking up indoors and alone in cars and the hysteria was rampant, businesses were being ruined and the CDC was riding high on a tidal wave of power, I was forced to get vaccinated as a condition of my employment. I had no immediate side effects, but ever since then I have had a low grade headache and felt generally much shittier than before the "Vaccine" ( also it isn't a vaccine). It was a mistake to take the vaccine. And both of my parents who were sick as hell after the first strain, have never been vaccinated and never got covid again.
