We've summarized the latest CDC guidance on vaccines and boosters below. Check our vaccination resources page for the latest guidance and resources.

Booster Shots

Who? CDC now recommends booster shots for everyone 12 years old and older.

When? Depends on which vaccine you received initially:

• Pfizer-BioNTech or Moderna: You should get a booster FIVE months after your last primary dose.
• Johnson & Johnson/Janssen: You should get a booster TWO months after your primary dose. 

Which vaccine should you get?

• CDC recommends the Pfizer-BioNTech vaccine for children and either the Pfizer-BioNTech or Moderna boosters for adults, regardless of which shot(s) you got initially.
• Johnson & Johnson’s Janssen vaccine is NOT recommended except in limited circumstances.
• You do NOT need to boost with the same vaccine you received initially.

Additional Primary Doses for People who are Immunocompromised:

Who? Moderately or severely immunocompromised people five and older who received initial doses of the Pfizer-BioNTech or Moderna vaccines.

When? 28 days after your second shot.

Which vaccine? Get the same vaccine you received for your first two doses. (CDC does NOT recommend mixing and matching for your additional dose).

Keep in mind: This is NOT the same as a booster shot, if you are 12 or older you should still get a booster shot after you complete your primary doses. In other words, you should get a booster five months after your third Pfizer or Moderna shot or two months after your single Johnson & Johnson shot.
