The present data about vaccine generated antibody has given Pfizer a 90+% success rate whether you have symptoms/side effects with the shots or not. Newer data on variants document risk of ICU level hospitalization when fully vaccinated is about 1/28,000.

Some people have a strong reaction to the Covid-19 vaccine and some do not. This has no bearing on whether your immune response was effective or not. The vaccines we have available have been shown to be over 90% effective and even more against severe disease, death, or hospitalization. The new variants may lessen the overall efficacy, but it is still well over 90% against severe disease.
