One of the studies also
compared the frequency of adverse reactions after the first dose of either the Pfizer or Moderna vaccine in 231 people who had either previously tested positive for SARS-CoV-2, or never been exposed to it. It found that symptoms such as pain or swelling at the injection site were similar in both groups of patients, but whole-body reactions, such as fatigue, headache, chills, fever, and muscle or joint pains, were more frequently reported by those who had recovered from COVID-19. What I'm reading and also noted in some research in Israel, is that a lot of these people getting some strong side effects after the 2nd dose, could have had covid and not even known it. Interesting ; This kinda follows true on some friends that never took this seriousness and "partied and hung out in a large group at the beach and 4 had some big side effects with their 2nd dose, and from lab test when they went to their doctor, 3 of these people had covid antibodies in their system. So they were carriers.,
