The Johnson & Johnson (Janssen) vaccine only requires one dose. If you got the Pfizer or Moderna one, you should have made the appointment for the second dose at the time you got the first shot. If not, you can schedule your second dose online at ourshot.in.gov or call 211.It’s important to make sure you receive the same type of vaccine for the second dose (Pfizer or Moderna). Vaccination site addresses can be found at ourshot.in.gov.
