What happens if you get COVID-19 between first and second shots?
It’s possible to become infected with COVID-19 between the first and second shots of the Pfizer and Moderna vaccines — and immediately following the second shot of these vaccines. If you do catch COVID-19 between the two vaccine doses, you should make sure to get the second shot once you’re feeling better.
When can you get a Moderna or Pfizer COVID-19 booster?
When should I get my booster shot? Eligible people who have received either the Pfizer or Moderna vaccine are allowed to get a booster shot at least six months after completing their initial two-shot vaccination series.

How many doses of COVID-19 vaccine will I need to get?
The number of doses needed depends on which vaccine you receive. To get the most protection:
- Two Pfizer-BioNTech vaccine doses should be given 3 weeks (21 days) apart.
- Two Moderna vaccine doses should be given 1 month (28 days) apart.
- Johnson & Johnsons Jansen (J&J/Janssen) COVID-19 vaccine requires only one dose.
If you receive a vaccine that requires two doses, you should get your second shot as close to the recommended interval as possible. However, your second dose may be given up to 6 weeks (42 days) after the first dose, if necessary.. You should not get the second dose earlier than the recommended interval.
