How do vaccines work in general?
You encounter thousands of germs every day. While your immune system can fight most of them on its own, vaccines help it fight the disease-causing ones (pathogens) it can’t handle.
Vaccines familiarize your immune system — which makes antibodies to defend your body against harmful invaders — with a certain pathogen so that it will know what to do if you become infected with that pathogen in the future.
How does the mRNA COVID-19 vaccine work?
How does the Moderna COVID-19 vaccine work?
Provides instructions the body uses to build a harmless piece of a protein from the virus that causes COVID-19. This protein causes an immune response that helps to protect the body from getting sick with COVID-19 in the future.
What does the Pfizer-BioNTech COVID-19 vaccine contain?
What does the COVID-19 vaccine do in your body?
Is there a live virus in the mRNA COVID-19 vaccines?

Nearly all of the ingredients in COVID-19 vaccines are ingredients found in many foods – fats, sugars, and salts.

Are egg products used in COVID-19 vaccines?
Does Johnson and Johnson COVID-19 vaccine have egg by product in it?
No food proteins like eggs or egg products, gluten, peanuts, tree nuts, nut products, or any nut byproducts (COVID-19 vaccines are not manufactured in facilities that produce food products).
Can the Moderna COVID-19 vaccine cause allergic reactions?
There is a remote chance that the Moderna COVID-19 Vaccine could cause a severe allergic
reaction. A severe allergic reaction would usually occur within a few minutes to one hour after
getting a dose of the Moderna COVID-19 Vaccine. For this reason, your vaccination provider
may ask you to stay at the place where you received your vaccine for monitoring after
vaccination. Signs of a severe allergic reaction can include:
• Difficulty breathing
• Swelling of your face and throat
• A fast heartbeat
• A bad rash all over your body
• Dizziness and weakness
