The vaccination site should have scheduled you for the second dose at the time you got the first dose, even if you didn’t have an appointment. If you did not schedule the second at the clinic, you can do so at ourshot.in.gov. You’ll need to make the appointment at the same site you got the first to assure you receive the same type of vaccine. If this is not possible, ask your local health department. Please remember that the Johnson & Johnson (Janssen) primary vaccine is only one dose.
