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 COVID-19 caused by SARS-CoV-2.

The FDA has authorized emergency use of the Pfizer vaccine in people who are 6 months to 4 years old.

COVID-19 vaccine does not contain coronavirus and cannot give your child 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.

Your child should not receive this vaccine if your child has ever had a severe allergic reaction to a Pfizer COVID-19 vaccine.

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

Ask your child's doctor if you are unsure about any COVID-19 treatments your child received.

Tell the vaccination provider if your child:

• has a fever;
• has any allergies;
• has had inflammation in or around the heart (myocarditis or pericarditis);
• has bleeding problems, or if your child uses a blood thinner (warfarin, Coumadin, Jantoven);
• has a weak immune system caused by disease or by using certain medicine;
• has received any other COVID-19 vaccine; or
• has fainted after receiving an injection.

Use Covid-19 (6M-4Y) Vaccine, Pfizer (2023-2024) (Intramuscular) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Get emergency medical help if your child has signs of an allergic reaction: hives, rash, dizziness, weakness, fast heartbeats, difficult breathing, swelling of the face, lips, tongue, or throat.

The vaccination provider may want to watch your child for a short time after the shot, to make sure your child does not have an allergic reaction. Your child will be treated quickly if there is a reaction right after receiving the vaccine.

Your child should not receive this vaccine if the first shot of COVID-19 vaccine caused an allergic reaction. The doctor or vaccination provider will determine if your child can safely receive this vaccine.

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

Some people receiving this vaccine had inflammation of the heart muscle or the lining around the heart within two weeks after receiving this vaccine, but the risk of this side effect is very low. Seek medical attention right away if your child has:

• chest pain;
• shortness of breath or breathing problems; or
• fast or pounding heartbeats or fluttering in your chest.

Common side effects may include:

• fever, chills;
• redness or a hardness and swelling where the shot was given;
• swelling or tenderness under the arm;
• nausea, vomiting;
• feeling tired; or
• headache, muscle pain, joint pain.

This is not a complete list of side effects and others may occur. Call the doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.

You may also use a smartphone-based program called V-safe to communicate with the Centers for Disease Control and Prevention (CDC) about any health problems your child has after receiving a COVID-19 vaccine: www.cdc.gov/vsafe.

Avoid receiving other vaccines without first seeking medical advice.
