Do I need a third dose or booster shot?

The Advisory Committee on Immunization Practices (ACIP) has recommended 3rd doses of Pfizer and Moderna for certain immunocompromised individuals. It is recommended to receive the same type of mRNA vaccine as the previous doses, spaced at least 28 days from the completion of the primary series. If you think that you may need a 3rd dose of COVID-19 vaccine, please call your doctor or medical provider for advice about your personal medical situation. Read who qualifies and more information from the CDC.

A “booster dose” refers to another dose of a vaccine that is given to someone who built enough protection after vaccination, but then that protection decreased over time (this is called waning immunity). The FDA and CDC formally authorized a booster dose of Pfizer vaccine, at least six months after the second dose, for certain populations. Read more about the recommendation here.

The CDC recommends that the following groups should receive a booster shot:

CDC also recommends that the following groups may receive a booster shot, based on their individual benefits and risk:

  • People ages 18-49 with underlying medical conditions
  • People ages 18-64 at increased risk for COVID-19 exposure because of the setting they work or live in

These recommendations only apply to people who previously received two Pfizer doses. This does not apply to individuals who received Moderna or Johnson & Johnson. Read Frequently Asked Questions around third doses and booster doses. Your healthcare provider, local pharmacy, and community vaccine sites can administer a booster. You can find local vaccine clinics at

How safe and effective is the vaccine?

Vaccines undergo a rigorous scientific process, which requires three phases of clinical trials before they can be submitted to the FDA for approval. In some instances, the FDA may issue an Emergency Use Authorization to allow an investigational vaccine to be available to the general public. Each vaccine currently available in the United States have been found to be safe and effective in preventing COVID-19. View safety and efficacy information on the CDC's website.  

If you have received the vaccine, you can report any adverse side effects through the CDC's V-safe After Vaccination Health Checker.

How much will it cost?

For the public: Vaccine providers will not be allowed to charge individuals for the vaccine. Providers will also not be allowed to turn someone away because of their inability to pay or medical coverage status. 

For providers: Most public and private insurance companies will cover any administration fees so there is no cost to get vaccinated. If this is not the case, or if someone does not have health insurance, providers may seek reimbursement through the CARES Act Provider Relief Fund.

What will I be asked to provide?

You may be asked for insurance information. This is solely for the vaccine provider to coordinate with insurance to receive reimbursement - you will not be charged. If you do not have insurance, you do not have to provide this information. You may be asked for your name, date of birth, phone number and address, and sometimes race and ethnicity. This information is only for data collection purposes. 

You do not need to be a U.S. citizen, and you will not need to prove lawful presence to get a COVID-19 vaccine in Colorado. The Department of Homeland Security announced that vaccination sites will be considered sensitive locations. This means that ICE will not carry out enforcement activities at or near vaccination sites. 

I already had COVID-19. Do I still need to be vaccinated?

Yes, you should be vaccinated regardless of whether you already had COVID-19. That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible—although rare—that you could be infected with the virus that causes COVID-19 again. Learn more about why getting vaccinated is a safer way to build protection than getting infected.

If you were treated for COVID-19 with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting a COVID-19 vaccine. Talk to your doctor if you are unsure what treatments you received or if you have more questions about getting a COVID-19 vaccine.

When will I be protected from COVID-19 after vaccination?

You will be protected against COVID-19 two weeks after your second dose of Pfizer or Moderna, or two weeks after your single dose of Johnson & Johnson (Janssen). Continue to follow public health guidance:

  • If you are partially vaccinated, it is recommended to wear a mask in public.
  • Maintain at least 6 feet of physical distance from others not in your household. Avoid large crowds and gatherings. 
  • Wash your hands.
  • Stay home when you are sick. Even if it's just the sniffles!

How is Broomfield ensuring equitable distribution of the COVID-19 vaccines?

Broomfield Public Health and Environment has developed a plan to drive localized efforts regarding equitable approaches to vaccine distribution in the Broomfield community. The plan is rooted in community engagement principles that harness the strengths of local partners, and builds trust with the community. The plan will be routinely reviewed and adapted to be responsive to the needs and input of the community. 

The primary strategies are:

  • Use data to inform targeted approaches
  • Activate new and existing partnerships to promote equity and address barriers to access
  • Ongoing efforts to provide information and build trust through responsive approaches

These strategies will be evaluated on an ongoing basis to ensure that all of Broomfield's residents are able to access the COVID-19 vaccine.
