The timing between your first and second shot depends on which vaccine you received. You should not get the second dose earlier than the recommended interval.
- If you received the Moderna vaccine, you will need to wait at least 24 days after your first dose.
- If you received the Pfizer vaccine, you will need to wait at least 21 days after your first dose.
You will need to complete the series of the 2 shots in order for them to work. Get the second shot even if you have side effects after receiving the first shot, unless a vaccination provider or your doctor tells you not to get a second shot.
