Individuals are considered fully vaccinated: 2 weeks after their second dose in a 2-dose series, like the Pfizer or Moderna vaccines, or 2 weeks after a single-dose vaccine, like Johnson & Johnson’s Janssen vaccine If it has been less than 2 weeks since your shot, or if you still need to get your second dose, you are NOT fully protected. Once you're fully vaccinated, it's important that you continue to take precautions and follow public health guidance. Visit the CDC for guidance for fully vaccinated people.
