1) How does the vaccine work? Does it contain a live virus or is it inactivated?

  • mRNA take advantage of the process that cells use to make proteins in order to trigger an immune response and build immunity to SARS-CoV-2, the virus that causes COVID-19.

  • mRNA vaccines do not contain a live virus. Most vaccines use weakened or inactivated versions or components of the disease-causing pathogens to stimulate the body's immune response to create antibodies.


2) Is the vaccine that helpful? I heard COVID-19 gives you better and longer immunity than the vaccine. Can it actually make my illness worse if I do get COVID?

  • Scientists are still learning more about the virus that causes COVID-19. It is not known if the disease will protect everyone against it or how long that protection actually lasts. Long-term health issues after recovery from COVID-19 have been found. 

3) How many shots will I need?

  • Two given several weeks apart to provide the best protection against the virus. The first shot primes the immune system and the second strengthens the immune response. The same vaccine must be used for both shots.

4) How much will the shot hurt? Can it cause me to get sick?

  • The most common side effect is arm soreness and stiffness comparable to shingrix (shingles vaccine). A fever is a potential side effect and can last a few days. Most symptoms resolve within a week after administration if not seek medical care. The vaccine does not give you COVID-19 and the side effects are sign that the immune system is working.
