On September 24, 2021, the Center for Disease Control and Prevention (CDC), aligned with the Food and Drug Administration (FDA) in recommending Pfizer Covid-19 booster shots for U.S. adults 65 and older as well as individuals age 50-64 with underlying conditions placing them at higher risk for severe COVID-19. The CDC is also allowing individuals 18 or older at higher risk for exposure to SARS-CoV2, including healthcare workers, frontline workers and first responders, to get a booster dose if they choose. Similarly, individuals 18-49 with the same underlying conditions may elect to get a booster vaccine dose.
Denver Health plans to offer Pfizer booster shots starting Friday, September 24, 2021 to all staff and eligible patients who have completed the primary Pfizer vaccine series at least 6 months ago.
REMINDER: this only applies to those receiving their initial vaccination with the Pfizer COVID-19 vaccine.
You can schedule an appointment for your booster dose in the following ways:
Access your MyChart account to find an appointment.
Call the appointment center at 303-436-7000
While vaccination remains the most important measure we can take to prevent COVID-19 and its complications, adherence to additional prevention measures such as universal indoor masking remains essential to protect ourselves, families, patients, and staff from COVID-19.
Frequently Asked Questions
Where can I get a COVID-19 booster shot?
You can schedule your vaccine in any of our ACS clinics. You can also schedule an appointment for our main campus vaccine clinic in Pavilion G, M-F 9-12, 1-4pm. Alternatively, you can receive the vaccine at any outside pharmacy offering Pfizer vaccine or other vaccination site if it is more convenient to you.
Will I be required to get a COVID-19 booster shot?
Currently persons who completed the primary two does series with Pfizer vaccine are considered fully vaccinated by the CDC. We are awaiting any further state guidance, but at this time it is not expected that boosters will be required.
Can I receive a booster shot if I received the Moderna vaccine?
No, the FDA has not approved Moderna booster shots for healthcare workers yet. We will update you when this changes.
Can I receive a booster shot if I received the Johnson and Johnson vaccine?
No, the FDA has not approved Johnson and Johnson booster shots for healthcare workers yet. We will update you when this changes.
Can I receive the influenza vaccine on the same day as the Pfizer booster vaccine?
Yes! The CDC has updated their guidance on the timing of the COVID-19 vaccine. You no longer need to space out the COVID-19 vaccine from other vaccines. You can get more than one vaccination at the same time.
Will additional booster shots be needed every year?
We don’t know the frequency with which booster shots will be necessary. We will update you as we obtain more information.
Do I need to wear a mask after receiving a Pfizer booster shot?
Yes, we require all employees to wear a mask when indoors at Denver Health due to the continued high levels of COVID-19 in the community.
How much additional benefit does the Pfizer booster shot provide to me?
In a large nationwide study, a third dose of the Pfizer vaccine given at least 5 months after completion of the initial two dose series resulted in an 11-fold decreased risk in developing confirmed COVID-19 infection 12 days or more after the booster compared to vaccinated persons who did not get the booster in person age 60 or older. In this same study the rate of developing severe COVID-19 was reduced 20-fold with boosters.1 A smaller study showed a 5-fold increase in effective antibody levels after a booster dose in persons age 18-55. 2 The increase in effective antibody levels was even higher for those over age 65.
When will vaccine be available for my family members who are under 12 years old?
We anticipate that the FDA will review the data on childhood vaccinations in the coming weeks.
How long do I need to be monitored after my booster vaccine?
A period of monitoring is recommended after all vaccines, however, persons who have had their initial COVID-19 vaccination series without a serious reaction (rash, hives, swelling or trouble breathing) are not required to stay in the vaccination area after the booster.
Should I expect even worse side effects after the booster shot?
While everyone is different and it is impossible to predict for the individual, in a small study2 of a third Pfizer COVID-19 vaccine given about 8 months after the initial series, rates of adverse events were similar, but not worse, than those seen after the second shot.
