Booster Doses if You Received 2 Doses of Pfizer-BioNTech or Moderna

You’re eligible to get a booster shot if you’ve completed your primary series of vaccinations and it has been more than 5 months since your last dose.

Second Booster

Patients ages 50 years and older are recommended to get a second booster (for a total of 4 shots). It must be more than 4 months since your first booster.

Booster Doses if You Received 1 Dose of Johnson & Johnson

You’re eligible to get a booster shot if you’re 18+ and it’s been at least 2 months since you got a dose of Johnson & Johnson’s Janssen vaccine.

  • Age-appropriate mRNA vaccines are preferred over Johnson & Johnson for booster doses.
Second Booster

Patients ages 50 years and older are recommended to get a second booster (for a total of 3 shots). This second booster must be an mRNA vaccine (either Pfizer or Moderna), and it must be more than 4 months since your first booster.

What if you’re immunocompromised?

Immunocompromised patients receive 3 doses in their primary series of mRNA vaccine instead of 2. The third shot in an immunocompromised patient’s primary series is administered 4 weeks after the second shot. After booster shots, an immunocompromised patient will receive 5 total shots.

Examples of “moderate to severe immunosuppression” include: Asplenia, Cancer (Solid Tumor and Hematologic Malignancies), Chronic Renal Disease, HIV, and Organ/Bone Marrow Transplant, along with patients who are taking immune-suppressive medications for autoimmune conditions such as Colitis, Lupus, Multiple Sclerosis, Psoriasis, and Rheumatoid Arthritis. It’s estimated that 2.7% of US adults are immunocompromised patients.

First Booster

Immunocompromised patients must be at least 3 months from administration of their third vaccine (completion of their primary series) to receive a first booster dose. It’s recommended to receive the same manufacturer as the initial vaccine series.

Second Booster

Immunocompromised patients must be at least 4 months from administration of their third vaccine to receive their second booster dose. It’s recommended to receive the same manufacturer as the initial vaccine series.

What Else Should I Know?

  • Patients with compromised immune systems may still be at risk for COVID-19, even with the additional vaccine dose. They should continue to take precautions, including wearing masks, avoiding crowded, indoor, poorly ventilated places that are higher risk for spreading COVID-19, and practicing good hand hygiene.
  • Vaccine supply at JCMG remains strong and we are well prepared to administer booster doses to our patients.
