Getting your annual flu vaccine, and staying up-to-date with your COVID vaccines, helps prevent severe illness or hospitalization. Locate a flu vaccine or COVID vaccine near you.

If you have questions about any of the vaccine clinics in Colorado, call the state’s vaccine hotline at 877-CO VAX CO (877-268-2926). The hotline is available Monday through Friday, 8 a.m. to 8 p.m. and Saturday and Sunday, 9 a.m. to 6 p.m. in multiple languages. Vaccine information is also available from CDPHE’s COVID-19 Vaccine FAQ.

On May 11, the federal government will end its public health emergency declaration. Coloradans can continue to keep up to date on their vaccinations by visiting their primary care providers, retail pharmacies, or one of hundreds of vaccine providers.

Learn how to stay up-to-date with your COVID vaccines from the CDC.





Vaccine Information

COVID-19 Boosters

A bivalent booster that protects against the Omicron variants of COVID-19 is now available to individuals who have completed their primary vaccine series. Effective April 19, monovalent (original) mRNA COVID-19 vaccines (Pfizer and Moderna) are no longer recommended for use in the United States. The Centers for Disease Control and Prevention (CDC) currently recommend the following:

  • Adults 65 years and older may receive a second bivalent vaccine booster dose in consultation with their healthcare provider.
  • Individuals 12 years and older who have received the primary series should receive one bivalent Pfizer or Moderna booster at least two months after their last vaccine. You may receive either Pfizer or Moderna, regardless of the type of primary series you received.
    • You may receive a bivalent booster even if you have previously received one or more monovalent (original) boosters.
  • Individuals 5 to 11 years of age are recommended to receive one updated bivalent booster at least two months after their last vaccine.
    • Children aged 5 years who received the Pfizer primary series may only get a Pfizer booster; children aged 6 to 11 may get either the Pfizer or Moderna bivalent booster.
    • Children aged 5 years who received the Moderna primary series may get either the Pfizer or Moderna booster.
  • Infants and children 6 months to 4 years who completed the Moderna primary series are recommended to receive one updated Moderna booster at least two months after their last vaccine.
  • Infants and children 6 months to 4 years who received the Pfizer-BioNTech COVID-19 vaccine primary series are recommended to get one updated Pfizer booster at last two months after their last vaccine.
  • Individuals who are moderately or severely immunocompromised have different booster recommendations, including the option of receiving an additional bivalent booster, which are described by the CDC.

COVID-19 Vaccines During Pregnancy

It is safe and effective for women to receive a COVID-19 vaccine during pregnancy and while breastfeeding. Vaccination can also protect the newborn or infant who isn’t yet able to receive the vaccine.
