COVID-19 Vaccine FAQs
How does an mRNA vaccine work?
Is the COVID-19 vaccine safe?
Will the vaccine give me COVID-19?
No. According to the CDC, none of the authorized and recommended COVID-19 vaccines or COVID-19 vaccines currently in development in the U.D. contain the live virus that causes COVID-19.

Who should not get the vaccine?
You should not get the COVID-19 vaccine if you:
- had a severe allergic reaction after a previous dose of the vaccine or have had a severe allergic reaction to any ingredients of the vaccine.
- had an immediate allergic reaction, even if it was not severe, to any ingredient in an mRNA COVID-19 vaccine.
- have had an allergic reaction to PEG (polyethylene glycol) or polysorbate. Polysorbate is not in the vaccines but closely related to PEG which is included.

If you are pregnant, plan to be pregnant or breastfeeding, please talk to your doctor before getting vaccinated.
If you have already recovered from COVID-19, there are no recommendations by CDC on whether or not to get vaccinated. There is not enough information available to say if or for how long after COVID-19 infection someone is protected from getting it again (natural immunity). If you are currently infected with COVID-19, please wait until you have completed your quarantine period and are not experiencing symptoms before getting vaccinated.
If you have questions or concerns on whether to be vaccinated, please talk to your doctor.
What are the side effects of the COVID-19 vaccine?
The most commonly reported side effects of the vaccines include:
- Injection site pain and swelling
If you experience any of these side effects, these are normal signs that your body is building protection and should go away in a few days. The CDC still recommends getting the second shot even if you experienced side effects after the first shot, unless a vaccination provider or your doctor tells you otherwise.
Each individual that is vaccinated should report their side effects in the v-safe health checker platform right away.
