COVID-19 Vaccine FAQs

The Maricopa County Department of Public Health website is a great resource and has the most up-to-date information about the vaccine and distribution in the county.

General questions

Q. Who is eligible?

A: The FDA has granted full approval of the Pfizer-BioNTech vaccine (now also being marketed as Comirnaty) for individuals 16 years of age and older. Additionally, the FDA has authorized emergency use of the Pfizer vaccine for individuals 12 years of age and older, the Moderna vaccine for individuals 18 years of age and older, and the Johnson & Johnson/Janssen vaccine for individuals 18 years of age and older.

For more information, visit the Maricopa County COVID-19 Vaccine page.

Q. Where is the vaccine available?

A: The COVID-19 vaccines are available at many locations throughout the state, including traditional settings like retail pharmacies, larger doctor’s offices and neighborhood health centers that help bring the vaccine close to individuals’ homes or workplaces. Walk-ins are accepted at many locations, while others require an appointment, so we encourage you to check before you go. Find vaccine locations and appointments from:

Q. Is there a cost for the vaccine?

A: No, there is not a cost for the vaccine. However, you will enter your insurance or Medicare information during the scheduling process, as insurance or Medicare will be billed an administration fee. If you do not have insurance, the Health Resources and Services Administration, a government organization, will be billed for your administration fee.

Q. Is the vaccine safe?

A: Like all vaccines, COVID-19 vaccines must go through a rigorous and multi-step testing and approval process before they can be used. Developers of a vaccine must provide a large amount of data on its safety and effectiveness to meet the rigorous standards set by the FDA. There are also ongoing safety monitoring systems in place by the CDC and FDA to allow for continued monitoring of the vaccine.

Q. What are the side effects?

A: Side effects that have been reported for the COVID-19 vaccines are like those of other vaccines including joint pain, muscle pain, fatigue, fever greater than 100.4, chills and headache. But remember, side effects appear to be a good indication of a healthy immune response to fight the virus. Learn more about potential side effects.

Q. Are there any health-related issues that may impact my ability to get a vaccine?

A: Prior to scheduling your appointment, please discuss with your personal healthcare provider if you:

  • Are pregnant
  • Are breastfeeding
  • Have an immunocompromising condition
  • Had a COVID-19 infection in the last 90 days
  • Are currently sick with COVID-19 (COVID-19 vaccination should not be given if currently symptomatic or you are in your isolation period).

Q. Can I get the COVID-19 vaccine if I’ve received another vaccine (such as the flu vaccine) recently?

A: Yes, you no longer need to wait 14 days between vaccinations. Experience with other vaccines has shown that the way our bodies develop protection, known as an immune response, after getting vaccinated and possible side effects of vaccines are generally the same when given alone or with other vaccines. Learn more about the timing of other vaccines.

Q. Can I get COVID-19 or spread it to others from the vaccine?

A: It’s not possible to get COVID-19 or to spread COVID-19 to someone else from the vaccines. The Pfizer and Moderna vaccines are mRNA vaccines, which use only a gene from the virus to generate an immune response. The Johnson & Johnson vaccine is a viral vector vaccine, which uses a different, harmless virus to generate an immune response. None of these can cause COVID-19.

Q. Who should not get the vaccine? What if I have severe allergies?

A: For guidance on allergic reactions and who should not get the vaccine, please visit the Maricopa County Department of Public Health site, under Vaccine Safety.

Q. Can I get the COVID-19 vaccine if I’ve had the virus and recovered?

A: Yes, but there may be limitations if you have received specific treatments for COVID-19. For more information on this topic, visit this CDC information page.

Q. Will the COVID-19 vaccine cause me to test positive on COVID-19 viral tests?

A: No, these vaccines will not cause you to test positive on viral tests, which are used to see if you have a current infection. For more information on this topic, visit this CDC information page.

Q: Will this vaccine alter my DNA?

A: No, the vaccines will not alter your DNA. The Pfizer and Moderna COVID-19 vaccines are mRNA vaccines, but do not change a person’s DNA. The mRNA from a COVID-19 vaccine never enters the nucleus of your cells, where your DNA is kept. This means the vaccine does not interact with your DNA in any way. The Johnson & Johnson vaccine, which is a viral vector vaccine, uses genetic material that also does not integrate into your DNA.

Q: Are the vaccines effective against the many variants now circulating in the U.S.?

A: Viruses mutate all the time, which is another reason to get people fully immunized as quickly as possible. Viruses can't mutate as easily if they are not spreading and replicating. By receiving your vaccine, you’ll not only protect yourself and those around you from getting a severe COVID-19 infection, but you may also help prevent the further emergence of variants. Although the vaccines we have today potentially could be somewhat less effective against new variants in terms of preventing all symptoms, we believe they do prevent many mild to moderate cases, and remain highly effective (compared to no vaccination) against preventing severe cases, hospitalizations and deaths. Learn more about herd immunity through vaccination and how it will prevent further variants.

Q: If I received my vaccination at HonorHealth but lost my vaccination card, how can I access my proof of vaccination?

A: If you received your COVID-19 vaccination at an HonorHealth facility or at our drive-thru POD vaccination clinic, use MyChart to access proof of your vaccination.

  • Use your After Visit Summary: Log into MyChart and click Menu at the top left of your screen. You can either type “Immunization” in the Search the Menu field at the top of the dropdown, or you can click on Health Summary under the My Record section further down. Within the Health Summary section, click on the Immunizations tab. Each immunization given by an HonorHealth facility will display, along with the date you received your vaccines. To view the lot number or more details of your vaccination, use the View After Visit Summary button in the Visits tab.
  • Use the COVID-19 section: Log into MyChart and click Menu at the top left of your screen. You can either type “COVID” in the Search the Menu field at the top of the dropdown, or you can click on COVID-19 under the My Record section further down. Expand the Vaccines received section for more details, including the lot number and manufacturer. You can also use the Download/Export button to download a PDF of your vaccination record.
