I don't know if you guys got any side effects. After the first dose nothing happend (Pfizer), after the second dose I lost my breath after a couple of weeks, got dizzy during a walk, then lost consciousness, and was rushed to the hospital. They couldn't find anything wrong, but I had a seisure. I still took the 3rd dose but at an ER, but my co-workers thought I was an idiot for taking that risk after what happend after the 2nd dose.
What I learned was to not rush into physical activities quickly if you had a fever etc. My oxigene level was at 75% when I came to the hospital. I took moderna as the 3rd doze, but was very careful with physical activities, and nothing happend.
