Booster information

The CDC recommends a third dose for certain groups of people with weakened immune systems who received either the Pfizer-BioNTech or Moderna COVID-19 vaccine.

In addition, the Pfizer, Moderna, or Johnson & Johnson COVID-19 booster is available to anyone ages 18 and older. You’re eligible for a booster if:

  • Pfizer & Moderna: It’s been at least 6 months since your second dose
  • Johnson & Johnson: It’s been at least 2 months since your first dose  

You can mix and match vaccines. You do not need to get the same vaccine brand for your booster as your original COVID-19 vaccination. 

Use VaxFinder to find a pharmacy or other location to get your booster.

Steps to get your vaccination

You will not need copies of medical records or a note from your doctor or health care provider.

Individuals age 12-17 should only receive the Pfizer vaccine. Read more about vaccine safety.
