Frequently Asked Questions About Covid-19 Vaccines

We understand you may have many questions about COVID-19 vaccines.

Please see the frequently asked questions below as a resource to keep you informed and help answer questions.


Is the COVID-19 vaccine safe?
Yes. The vaccines underwent clinical trials with thousands of participants representing a range of diverse groups and has been deemed safe by the Centers for Disease Control and Prevention (CDC) and the U.S. Federal Drug Administration (FDA). Those with a history of reactions to immunizations are encouraged to talk to their healthcare provider prior to receiving the vaccine.

How was the COVID-19 vaccine made so quickly?
COVID-19 is not the first coronavirus. Scientists were able to apply 50 years of research to make a safe and effective vaccine, which received support for accelerated production.

How do COVID-19 vaccines work?
The Moderna and Pfizer-BioNTech COVID-19 vaccines are messenger RNA vaccines (mRNA). mRNA provides the instructions your body needs to build a small protein that triggers an immune response to COVID-19 if you become infected.

If I have already had COVID-19 and recovered, do I still need a vaccine?
Yes, you do. There is not evidence that recovering from a COVID-19 infection builds lasting immunity in the body. Some people have been infected with COVID-19 more than once/multiple times. It is recommended you wait 90 days from recovery to receive the vaccine.

Do I still have to wear a mask after I receive the vaccine?
Yes. It will take time to vaccinate enough people for immunity in the community. In the meantime, continue to be COVIDSAFE by wearing a mask, maintaining social distance, washing your hands, and avoiding large gatherings.

Are there side effects?
Common side effects include soreness in your arm, fatigue, body aches and fever. These are signs the vaccine is working.
