Yes, you’re fully vaccinated even if you haven’t had a booster shot

“To date, to be considered fully vaccinated requires two doses of the Pfizer-BioNTech or Moderna vaccines or alternatively one dose of the Johnson & Johnson COVID vaccine. At this time, the booster shots are not required for individuals to be classified fully vaccinated,” says Phil Felgner, PhD, the director of the Vaccine Research and Development Center at the University of California in Irvine.
