Wrong.
I was at a family gathering over Labor Day weekend. I did get covid as did another relative, but very mild symptoms. First time I have gotten it when everyone around me has had it from the start if the scamdemic. The others that got it all were vaxxed. And guess what? All on meds and all way sicker.
Also those I work with that are getting it are vaccinated. Some have had it twice since vaccinated.

I feel the only reason I caught it this time around was that I was already getting over a sinus infection from allergies and my immune system was down.
