Are boosters available?

Yes, boosters of the Moderna, Pfizer and Johnson & Johnson vaccines are authorized and recommended by the FDA and CDC for all adults and for children ages 12+ who are immunocompromised. Here’s what to know.

  • Ages 18+ who were vaccinated with Pfizer or Moderna at least 6 months ago can receive a booster shot.
  • Ages 18+ who were vaccinated with Johnson & Johnson at least 2 months ago can receive a booster shot.
  • Ages 12+ who are immunocompromised and were fully vaccinated at least 28 days ago with Pfizer can receive a booster shot.
  • Ages 18+ who are immunocompromised and were fully vaccinated at least 28 days ago with Moderna can receive a booster shot.
  • Regardless of the vaccine you already received, if you are 18+ you can receive Pfizer, Moderna or Johnson & Johnson for your booster shot. (If you are under 18, you can only receive Pfizer.)

Can I get a booster of Moderna or Johnson & Johnson at Henry Ford?

We support and encourage you to receive a Moderna or Johnson & Johnson booster when you are eligible. Boosters of Moderna and Johnson & Johnson are not available at our Primary Care sites. We offer only the Pfizer vaccine. If you prefer Moderna or Johnson & Johnson for your booster, please visit www.Michigan.gov/covidvaccine for Moderna and Johnson & Johnson vaccine sources near you.

Can we “mix and match” vaccines?

Yes, the FDA and CDC have advised that boosters of Pfizer, Moderna and Johnson & Johnson are interchangeable. This means:

  • If you had Pfizer or Moderna for your first two shots at least six months ago, you can receive any vaccine for a booster.
  • If you had Johnson & Johnson at least two months ago, you can receive any vaccine for a booster.

Henry Ford only offers boosters of Pfizer. If you make an appointment for a booster at one of our Primary Care sites, you will be able to receive the Pfizer vaccine.

Will the third shot improve my protection against the Delta variant?

Yes, it will improve your protection against all strains of the COVID-19 virus, including the Delta variant. It will also reduce the chances of getting very sick, if you do contract COVID-19.

If appointments at Henry Ford are full, should I wait until an appointment is available to get a booster dose from Henry Ford?

No, you should not wait. We encourage you to get a booster when you are eligible. Please use one of the many other sources for boosters. Visit www.Michigan.gov/covidvaccine for options near you

Will I have to bring my COVID-19 vaccination card to my appointment?

No, but if you do bring your COVID-19 vaccination card, we will add the booster to your card.

Is the booster different from the original two shots?

Pfizer and Johnson & Johnson are the same as the original shots. Moderna is half the dose of the first two shots.

Will side effects be worse after the booster?

Side effects after a booster of Moderna or Pfizer are similar to what people experienced after receiving the first two shots. Most symptoms are mild to moderate, and the most common side effects are fatigue and injection-site pain.

People who received a booster of Johnson & Johnson reported milder side effects than the original shot.

What are the risks of getting the booster?

The safety profile is the same as for the first and second vaccine doses.

How effective is the booster shot?

Booster shots of mRNA coronavirus vaccines (Pfizer and Moderna) increase antibodies by about 10 times.

Johnson & Johnson given two months after the first dose increases protection against moderate to severe disease from 85% to 94% and the amount of neutralizing antibodies increased four-fold. If the booster was given six months after the first shot, antibody levels increased 12-fold four weeks after the booster was given.

Will booster vaccines be developed that are different from the original vaccines?

Vaccine manufacturers are partnering with the U.S. government and other organizations to develop booster vaccines that may be designed to provide added protection against COVID-19 variants. Much like the current COVID-19 vaccines, researchers will evaluate booster vaccines to ensure they’re safe and to see how well they help people develop antibodies against the variants.
