Important Update Regarding COVID-19 Pfizer-BioNTech Boosters


Jefferson County, Colo. — The Centers for Disease Control and Prevention (CDC) has now approved COVID-19 vaccine booster doses for children aged 12-15. This announcement, made Jan. 5, 2022, comes following the Dec. 9 recommendation that adolescents ages 16 and 17 receive a booster dose. Now, COVID-19 booster doses are available for all people in our community ages 12 and up. COVID-19 vaccination — including boosters — remains the best way to protect yourself and your loved ones from COVID-19. 

In addition to extending the age range eligible for booster doses, CDC also has shortened the time frame in which individuals must wait after finishing their initial vaccine series from 6 to 5 months. This means the booster is now available to individuals 5 months after completing their primary Pfizer vaccine series. In addition, CDC has updated the recommended time frame for the Moderna vaccine from 6 to 5 months. The time recommendations for the Johnson & Johnson vaccine (2 months) has not changed. 

“The bottom line is this — vaccination works, and vaccines + boosters work even better,” said Dr. Dawn Comstock, Executive Director at Jefferson County Public Health (JCPH). “This announcement from the CDC could not have come at a better time. As our community is nearing the peak of infections from the omicron variant, we all needed a little hope — and a lot of science — to help us get through. That hope has come in the form of expanded booster eligibility.” 

In its announcement, CDC also updated its recommendation to approve third doses of the COVID-19 vaccine for moderately or severely immunocompromised 5 to 11-year-olds. Children who fall into this category are eligible to receive this third dose 28 days after receiving their second. 

Guide to who should get an additional dose of the COVID-19 vaccine:

You (or your child) should get another dose if you:

·       Are 12 or older and received your second dose of Pfizer at least five months ago.

·       Are 18 or older and received your second dose of Moderna at least six months ago.

If you got the Johnson & Johnson vaccine, you should get a dose of either Pfizer or Moderna two months or more after you first got vaccinated.

If you are immunocompromised and got three doses of Pfizer, you should get a fourth dose five months after your third. If you are immunocompromised and got three doses of Moderna, you should get a fourth dose six months after your third dose.

Anyone age 12 or older who is due for a third dose should make a plan to get one. JCPH encourages you to speak with your health care provider if you have questions.

There are many COVID-19 vaccination sites in Jeffco where residents can go to receive their vaccine — including both their initial series and their booster. All sites offer COVID-19 vaccines for free and no ID or insurance is required. For a complete list of COVID-19 vaccine locations across the county, including what ages they serve, visit
