COVID-19 Vaccine

Right now, Colorado is in phase 1A, 1B.1,1B.2, and 1B.3 of its phased COVID-19 vaccine distribution.
As we move through phases, people in previous phases remain eligible.
In many cases, Coloradans who are not yet eligible to receive the vaccine can still sign up to receive alerts with some vaccine providers-- and should use the vaccine provider map or the list of providers once eligible.
It’s important to know that vaccine providers may have varying amounts of vaccine during any given week. Vaccine providers are working as fast as they can to set up appointments for when they have the vaccine. Note that these locations are not open for walk-in appointments. They should be contacted directly for more information.
Learn more about who is currently eligible to receive a vaccination by visiting our Vaccines for Coloradans webpage.

2. If I have recovered from COVID-19 and completed my isolation period, do I still need to get vaccinated with a COVID-19 vaccine?: It is currently unknown how long natural immunity lasts after recovering from COVID-19. Early evidence suggests natural immunity from COVID-19 may not last very long in some people, and cases of reinfection have been reported. So even if you have had COVID-19 and recovered, you should plan to get a vaccine when it is your turn.

Yes. We’re still learning about the level of immunity that the vaccine provides, but so far the vaccines have only been proven to protect the recipient from symptomatic COVID-19 disease. You might still be able to have an asymptomatic infection (showing no symptoms) and be able to spread the virus to others after you have been vaccinated.
Until we know for certain, it is important to continue taking COVID-19 precautions. Continue wearing masks and practicing physical distancing. That is the best way to help protect your loved ones who have not yet had the opportunity to get the vaccine.

4. Can I get COVID-19 from a vaccine?: No. It is not possible to get COVID-19 from a vaccine, but you may feel some side effects like fever, chills, and fatigue. The current mRNA vaccines use temporary pieces of genetic code from the virus to stimulate your body’s immune response. This cannot cause COVID-19. The goal of the vaccine is to provide your body with the tools it needs to fight the COVID-19 virus if you were to get infected.

You may experience mild to moderate side effects after receiving the vaccine. Side effects typically go away on their own after a few days. The most commonly reported side effects are:
- Pain, swelling, and redness at the injection site.
- Pain, tenderness and swelling of the lymph nodes in the same arm of the injection.
- Fatigue.
- Headache.
- Muscle pain.
- Chills.
- Joint pain.
- Nausea/vomiting.
- Fever.
Different people may experience different side effects, even if they receive the same vaccine.
The process of building immunity can cause symptoms. These symptoms are normal and show that your body’s immune system is responding to a vaccine. Other routine vaccines, like the flu vaccine, have similar side effects.
If you experience discomfort after the first dose of the vaccine, it is very important that you still receive the second dose a few weeks later for full protection.
For in-depth information about the side effects of the vaccines, see the CDC’s report on the Pfizer vaccine and the Moderna vaccine.

6. How are the vaccines being allocated?: Vaccine allocations are being distributed proportionately based on county population. At this time, the Colorado Department of Public Health and Environment is making all vaccine allocation decisions due to a limited number of available doses and a short turnaround time between when doses are available in the vaccine ordering system and when orders are required to be placed. We anticipate that vaccine allocation may shift to the local level. Enrolled providers are able to communicate directly with the state on anticipated needs; however, there are a limited number of doses available each week.

7. Do I need to be a U.S. citizen to get the vaccine?: 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. Further, public health will never share your information for any immigration or law enforcement purposes.

In developing a vaccine for COVID-19, researchers had to work quickly, but not at the risk of anyone’s safety. Medical researchers did not cut any corners or skip any steps. Safety and effectiveness were the top priorities.
The timeline for developing COVID-19 vaccines was possible for several reasons:
- Researchers relied on years of previous research in other viruses and vaccines to help inform a vaccine development process for COVID-19.
- Everyone involved dedicated all their resources and time to developing a COVID-19 vaccine. This includes research institutions, pharmaceutical companies, government agencies, and philanthropic organizations.
- Many governments around the world, including the U.S. government, and private funders invested in the vaccine, which allowed pharmaceutical companies to focus on research right away.
- Finally, because of the financial support, researchers were able to conduct different parts of the development process on parallel tracks instead of one after another. Usually, each phase in a clinical trial ends before the next phase begins, with several months to a year or more in between each phase. Because of the emergency presented by the pandemic, researchers developed the vaccines on parallel tracks, meaning that they completed the necessary steps at the same time or with some overlap. No steps were skipped in the process of developing the COVID-19 vaccines.

9. How do I become a vaccine provider?: The state is enrolling all vaccine providers. For more information visit the state’s website.
