Are you willing to get the Covid vaccine when offered?

The best place to get any kind of info on possible side effects should be Pfizer's own vaccine information fact sheet. They are pretty up front about everything because they want to make sure they are covered legally.

Also note that it was updated to include myocarditis and pericarditis due to outside studies and their own studies showing links to them both from the vaccine. This was not previously on the factsheet. So it does show they will update the vaccine information fact sheet over time as other potential side effects become known.
