You should schedule your second dose appointment when you get your first dose and at the same location. You can call 211 to reschedule at any time or by using the link sent via text or email 48 hours before your appointment. If under extreme circumstances you cannot return to the clinic where you received your first dose to get your second one, please contact your local health department to find a site where you can receive the same type of vaccine you got for your first shot (Moderna or Pfizer). Please remember if you received the Johnson & Johnson (Janssen) vaccine, it is only one dose and does not require a second appointment.
