The timing between your first and second dose will depend on which vaccine you received:

  • If you received the Pfizer/BioNTech vaccine, the CDC recommends you get your second dose 3 weeks (or 21 days) after your first.
  • If you received the Moderna vaccine, the CDC recommends you get your second dose 4 weeks (or 28 days) after your first.
  • If you received the Johnson & Johnson/Janssen vaccine, the vaccine is single-dose and you do not need a second dose.

 

You should get your second dose as close to the recommended 3-week or 4-week interval as possible. You should not get your second dose early. Most providers will ask you to schedule your first and second vaccination at the same time and will help you set up reminders via text, email, or phone call about your second dose.
