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 Pfizer COVID-19 vaccine is used to help prevent COVID-19 caused by SARS-CoV-2 in people who are 12 years 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.

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);
• you have a weak immune system caused by disease or by using certain medicine;
• you are pregnant, plan to become pregnant, or breastfeeding;
• you've received any other COVID-19 vaccine; or
• you have fainted after receiving an injection.

Use Covid-19 (12Y+) 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 you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

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 if the first shot of COVID-19 vaccine caused an allergic reaction. Your doctor or vaccination provider will determine if you can safely receive this vaccine.

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

Some people receiving this vaccine had inflammation of the heart muscle or the lining around the heart within the first week after receiving this vaccine, but the risk of this side effect is very low. Seek medical attention right away if you have:

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

Common side effects may include:

• fever, chills;
• pain, bruising, swelling, or irritation where the shot was given;
• feeling tired; or
• headache, muscle pain, joint pain.

This is not a complete list of side effects and others may occur. Call your 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 you have after receiving a COVID-19 vaccine: www.cdc.gov/vsafe.

Avoid receiving other vaccines without first seeking medical advice.
