I can only speak from my experience.
My immediate family recieved the complete vaccine regime. We isolated and wore masks when out and about. We had no ill affects from the vax nor did we contract the virus.
We have neighbors and coworkers who scoffed at the guidelines. A coworker (unvaxd) contracted Covid leading to his death. He was in his 30s. A neighbor contracted Covid, also not vaxd, she was not hospitalized, but endured a long, long recovery. To this date, she still suffers from diminished lung capacity, low endurance, foot & lower leg problems and taste/smell is altered. These are just 2 people we personally know, we have others within our circle who also scoffed and end up ill.
In the beginning of the pandemic, there was a large amount of misinformation. Some of the mythinformation has transformed into conspiracy and now is construed as fact.
So, believe what you want. Speak based on YOUR experience, not your perceptions.
