Why should I stay up-to-date with my COVID-19 vaccinations?

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.

What factors can increase the risk for severe illness from COVID-19?

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

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.
