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 bivalent vaccine is used to help prevent severe disease and death from COVID-19 caused by SARS-CoV-2.
The FDA has authorized emergency use of the Pfizer bivalent vaccine in people who are 6 months to 4 years who:
- have not begun the three-dose primary series of Pfizer; or
- have not received the third dose of the primary series of Pfizer.
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 is the most important information I should know about Pfizer-Biontech Covid-19 (6M-4Y) Bivalent Vaccine Pf (Intramuscular)?
You should not receive this vaccine if you've ever had a severe allergic reaction to a Pfizer COVID-19 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.
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);

Read all vaccine information sheets provided to you.
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.
Keep using infection control methods when you are in public or around others who may not have been vaccinated. This includes social distancing, hand-washing, using protective face covering, disinfecting surfaces you touch a lot, and not sharing personal items with others.
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.
