Among patients receiving mRNA vaccines, clinically significant symptoms were more frequent following dose 2, following dose 1 in patients with previous SARS-CoV-2 infection, and in those who received the Moderna vaccine.

New @JAMA_current paper says @moderna_Tx caused 2.3x the number of "significant" symptoms compared to @pfizer in a sample of 950 people.
Moderna also produced more antibodies. Raising the question of what a third dose, which produces still MORE, will do.https://t.co/drvhhsnpHo

Did you hear vaccinated people with Delta “have just as much virus in their nose so are just as infectious as unvaccinated”?
Turns out vaccinated people have significantly less culturable virus present at the same Ct count
They are LESS INFECTIOUS 💥 https://t.co/OX0Ul0ntWc pic.twitter.com/3vDQSJ6j84

This is not real evidence supporting real policy choices as they are really carried out in the real world.
Instead, this is theoretical bioplausibility spun into a full paper.
