Am I Protected after COVID-19 infection or Vaccination?

Overview

Pandemic policy interventions, such as the timing of vaccine boosters, take into account the length and efficiency of protection from infection with and immunization against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The threshold for preventing a symptomatic SARS-CoV-2 infection may be lower than the threshold for preventing all infections. Vaccination has been demonstrated to provide longer-lasting protection against hospitalization and mortality than it does against symptomatic and asymptomatic illness, according to recent studies.
