If youre fully vaccinated with the pfizer vaccine, are you likely safe from infection? and if caught, definitely okay from death?

The best thing you can do is to become vaccinated. While no vaccine is 100% effective, reports are that well over 90# of people currently hospitalized for Covid-19 are unvaccinated. Death rate among vaccinated individuals is well under 1%, and much lower than the chance not being struck by lightning. Getting vaccinated is the smartest thing you can do.

So far a person fully vaccinated with the currently available vaccines is less likely to become symptomatic or hospitalized or die, but its not 100%.
