COVID-19 (coronavirus 2019) vaccine, Moderna

What is the most important information I should know about this vaccine?

What is the COVID-19 vaccine?

COVID-19 is a serious disease caused by a coronavirus called SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). COVID-19 is spread from person to person through the air.

COVID-19 can affect your lungs or other organs. Symptoms may be mild or serious and include fever, chills, cough, sore throat, shortness of breath, tiredness, body aches, headache, loss of taste or smell, runny or stuffy nose, nausea, vomiting, or diarrhea.

The COVID-19 vaccine is used to help prevent severe disease and death from COVID-19 caused by SARS-CoV-2.

The US Food and Drug Administration (FDA) has fully approved the Moderna vaccine for active immunization to prevent COVID-19 in people 18 years of age and older.

COVID-19 vaccine does not contain coronavirus and cannot give you COVID-19. This vaccine will not treat an active COVID-19 infection.

Like any vaccine, COVID-19 vaccine may not provide protection in every person.

What should I discuss with my healthcare provider before receiving this vaccine?

If you are infected with COVID-19, are waiting for testing results, or are exposed to someone infected with COVID-19: You may not be able to receive this vaccine until you have no symptoms and/or your required quarantine period has ended. Receiving this vaccine will not make you less contagious to other people if you are infected with COVID-19 but you have no symptoms.

If you had COVID-19 and were treated with monoclonal antibodies or convalescent plasma: You should wait 90 days before getting a COVID-19 vaccine. Ask your doctor if you are unsure about any COVID-19 treatments you received.

Tell your vaccination provider if:

• you have a fever;
• you have any allergies;
• you have had inflammation in or around your heart (myocarditis or pericarditis);
• you have bleeding problems, or if you use a blood thinner (warfarin, Coumadin, Jantoven);
• you have a weak immune system caused by disease or by using certain medicine;
• you are pregnant or breastfeeding;
• you've received any other COVID-19 vaccine; or
• you have fainted after receiving an injection.

COVID-19 is more likely to cause serious illness or death in a pregnant woman. Not all risks are known yet, but this vaccine is likely to be less harmful than becoming infected with COVID-19 during pregnancy.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of COVID-19 vaccine on the baby.

How is this vaccine given?

Read all vaccine information sheets provided to you.

The Moderna COVID-19 vaccine is given as an injection (shot) into a muscle, in a series of 2 shots given 1 month apart.

The Moderna vaccine may be given in a series of 3 shots to adults who have received an organ transplant or have certain types of immunosuppression. The first 2 shots are given 1 month apart and the third shot is given at least 28 days after the second shot.

The first booster dose is given to people 18 years and older at least 5 months after you received all required doses of the Moderna COVID-19 vaccine. You should receive Moderna or Pfizer COVID-19 vaccine for your booster doses.

The second booster dose of Moderna COVID-19 vaccine is given to people 50 years and older at least 4 months after the first booster dose was given. A second booster dose of Moderna COVID-19 vaccine can also be given at least 4 months after the first booster dose to people 18 years and older who have received an organ transplant or have certain types of immunosuppression.

Your doctor or vaccination provider will determine whether you need a booster dose.

You will receive a reminder card showing the date and type of each injection. Take this card with you each time you receive a COVID-19 vaccine.

You will be "fully vaccinated" if it has been at least 2 weeks since you received your last dose of this vaccine. You may become infected with COVID-19 if the vaccine has not had enough time to provide protection.

Receiving a COVID-19 vaccine will not cause you to test positive on a coronavirus test. However, once your body develops immunity to COVID-19, you could test positive on an antibody test (a test to detect immunity in your body from previous exposure to coronavirus).

It is not known how long this vaccine will protect you from infection with COVID-19. It also is not known how long immunity will last in a person who's been infected with and recovered from COVID-19. COVID-19 vaccine is still being studied and all of its risks are not yet known. Updated federal public health recommendations may be found at https://www.cdc.gov/coronavirus/2019-ncov/vaccines/fully-vaccinated-guidance.html

What happens if I miss a dose?

What happens if I overdose?

An overdose of this vaccine is unlikely to occur.

What should I avoid after receiving this vaccine?

Avoid receiving other vaccines without first seeking medical advice.

What are the possible side effects of this vaccine?

Your vaccination provider may want to watch you for a short time after your shot, to make sure you don't have an allergic reaction. You will be treated quickly if you have a reaction right after you receive the vaccine.

You should not receive this vaccine again if the first shot caused an allergic reaction. Your doctor or vaccination provider will determine if you can safely receive another COVID-19 vaccine.

Not all possible side effects are known. Becoming infected with COVID-19 is much more dangerous to your health than receiving this vaccine.
