COVID-19 Vaccine Boosters for Those With Underlying Medical Conditions
COVID-19 vaccines continue to be highly effective at preventing severe illness, hospitalization, and death due to COVID-19, including from the Delta variant. But protection appears to decrease over time, and people with underlying medical conditions are at increased risk of severe illness from COVID-19. As a result, some people are now eligible for a booster shot.
Who Is Eligible for a Booster
You’re eligible to get a booster shot if:
- It's been at least 6 months since you got the second dose of a Pfizer-BioTech or Moderna vaccine;
You're at least 18 years old; and
- You're at increased risk for severe COVID-19 because of an underlying medical condition.
Such conditions include:
- Chronic kidney disease
- Chronic lung diseases, including COPD (chronic obstructive pulmonary disease), asthma, interstitial lung disease, cystic fibrosis, and pulmonary hypertension
- Dementia or other neurological conditions
- Type 1 or 2 diabetes
- Down syndrome
- Heart conditions, such as heart failure, coronary artery disease, cardiomyopathies or hypertension
- HIV infection
- Liver disease
- Overweight and obesity
- Sickle cell disease or thalassemia
- Smoking, current or former
- Solid organ or blood stem cell transplant
- Stroke or cerebrovascular disease, which affects blood flow to the brain
- Substance use disorders
If you have a condition that is not listed above, your health care provider can help you decide if a booster is right for you.
CDC recommends that all individuals who are at least 18 years old and who got Johnson & Johnson’s Janssen vaccine—regardless of whether you have an underlying medical condition—get a booster at least 2 months after your first dose.
If you're eligible for a booster, you may choose which vaccine to receive as a booster dose. Your booster shot doesn't have to be the same vaccine you received before.
For more information about boosters, or if you have questions about your eligibility, visit cdc.gov/coronavirus or talk to a health care provider.
