CDC recommends the 2023-2024 Formula updated COVID-19 vaccines for eligible individuals 6 months of age and older. These vaccines more closely target the XBB lineage of the Omicron variant and could help restore protection against COVID-19, including against serious illness, that may have decreased over time.

As with other vaccine-preventable diseases, you are best protected from COVID-19 when you stay up-to-date with the recommended vaccinations.

The CDC has identified certain factors that can increase one's risk of getting very sick from COVID-19. They include:

• Age 50 years or older
• Cancer
• Chronic kidney disease
• Chronic liver disease
• Chronic lung diseases
• Cystic fibrosis
• Dementia or other neurological conditions
• Diabetes (type 1 or type 2)
• Disabilities
• Heart conditions
• HIV infection
• Immunocompromised condition or weakened immune system
• Mental health conditions
• Obesity or being overweight
• Physical inactivity
• Pregnancy or recent pregnancy
• Sickle cell disease or thalassemia
• Smoking, current or former
• Solid organ or blood stem cell transplant
• Stroke or cerebrovascular disease
• Substance use disorders
• Tuberculosis

The list above does not include all possible conditions that put you at higher risk of severe illness from COVID-19. The conditions on this list are in alphabetical order. They are not in order of risk. People with certain risk factors have an increased chance of getting very sick from COVID-19. Understanding your COVID-19 risk can assist you in making decisions about how to help protect yourself and those you take care of. Take this list with you to review with your doctor at your next appointment.
