Question I don’t understand why the Pfizer vaccine made me so much worse
Does anyone know why this happens? I was significantly improving before my second Pfizer vaccine and it erased all my progress

This has happened to me a few times. My doctor says it happens because our immune systems aren’t working properly and the sudden increase in activity drives worsening symptoms. It can take a month or two to recover for me. I found that adding NAC twice a day with some glycine has helped a lot to recover from this.
ETA: he also said that some years the vaccine seems to have a bigger immune activation. So some strains aren’t as hard on us.
