If you remember the chronology of the vaccine release, I believe it was ready around Jan of 2021? But only emergency personal/medical staff could get it first, then people with comorbidities, and the elderly after maybe 6-8 weeks.
As time went on and everybody was allowed to get the vaccine, the majority of the reports were coming out with serious issues around the shot itself. For folks like us, it was mostly too late. I will say there was early debate even in February of 2021 here on Free Republic, and many people were warned about it. My decision to get the shot was based on my own medical issues despite knowing there were risks. I never argued for others to get it, just that for me it made sense.
If I had to do it all over again I would not. I took it to avoid Covid but still got Covid 3 times. One of those was really bad. I came close to asking to be put in the hospital, but stuck it out at home and got better eventually. The second and third time was just like a cold. I think what killed the most people with Covid, especially older folks, was going on the ventilator. I told my son I am NEVER to be put on a ventilator. Anyway, the fact that I got Covid 3 times in my mind meant the vax failed. Just using logic.
