COVID-19 Vaccines for People at Increased Risk for Severe Illness from COVID-19
Adults of any age with certain underlying medical conditions are at increased risk for severe illness from the virus that causes COVID-19. COVID-19 vaccines are recommended for and can be administered to most people with underlying medical conditions.

If you have questions about getting COVID-19 vaccine, you should talk to your healthcare providers for advice. Inform your vaccination provider about all your allergies and health conditions.
People with underlying medical conditions at increased risk from COVID-19
People aged 16 years and older who have underlying medical conditions that increase the risk of serious, life-threatening complications from COVID-19, should be among those offered COVID-19 vaccine first. CDC’s recommendations are based on those of the Advisory Committee on Immunization Practices (ACIP), an independent panel of medical and public health experts.
The list of high-risk medical conditions that put people at increased risk for severe COVID-19-associated illness is updated routinely as new data become available.
Medical Conditions in Adults
This list is presented in alphabetical order and not in order of risk.
CDC completed an evidence review process for each medical condition on this list to ensure they met criteria for inclusion on this webpage.
We are learning more about COVID-19 every day, and this list may be updated as the science evolves.
Cancer
Having cancer can make you more likely to get severely ill from COVID-19. Treatments for many types of cancer can weaken your body’s ability to fight off disease. At this time, based on available studies, having a history of cancer may increase your risk.

Immunocompromised state (weakened immune system)
Having a weakened immune system can make you more likely to get severely ill from COVID-19. Many conditions and treatments can cause a person to be immunocompromised or have a weakened immune system. Primary immunodeficiency is caused by genetic defects that can be inherited. Prolonged use of corticosteroids or other immune weakening medicines can lead to secondary or acquired immunodeficiency.

Overweight and obesity
Overweight (defined as a body mass index (BMI) > 25 kg/m2 but < 30 kg/m2), obesity (BMI ≥30 kg/m2 but < 40 kg/m2), or severe obesity (BMI of ≥40 kg/m2), can make you more likely to get severely ill from COVID-19. The risk of severe COVID-19 illness increases sharply with elevated BMI.
