You will be asked to sign up for your second vaccination when you get the first one. An appointment confirmation will be sent to you by text or email after the appointment is made. The confirmation will include the date and time of the appointment and the name of the vaccination site. If you do not sign up for a second vaccination when you get the first one, a reminder will be sent by text or email. Please remember that the Johnson & Johnson (Janssen) primary vaccine is only one dose.
