I seen somewhere that the covid 19 vaccine pfizer can cause cancer and encephalitis and i got that vaccine and now im worry about that was wording if its true and was wording what is encephalitis and can that be cured?

While some side effects from COVID-19 vaccines have been reported, there is no evidence of Pfizer (or other COVID-19 vaccines) vaccines "causing cancer" or encephalitis.

So far, no reports of encephalitis (brain infection or diffuse inflammation), or specific cancers from either m-RNA vaccines. You can go to "somewhere" if you wish, and read whatever. If you wish current medical facts, you have come to the right source.
