Be sure to notify your doctor of any side effects that occur after you receive this vaccine.

This vaccine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you have a rash, itching, a fast heartbeat, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after receiving the vaccine.

This vaccine may increase your risk of serious heart problems (eg, myocarditis, pericarditis), especially after you receive the second dose. Check with your doctor right away if you have anxiety, blue or pale skin, chest pain, possibly moving to the left arm, neck, or shoulder, fever, chills, a fast heartbeat, trouble breathing, or unusual tiredness or weakness.

Fainting may occur after you receive this vaccine. You may also have vision changes, numbness or tingling in your arms, hands, or feet, or jerky movements of the arms and legs. Your doctor may want you to be observed after you get the injection to prevent and manage fainting.

This vaccine may not protect everyone who receives it. This vaccine will not treat symptoms of COVID-19 infection if you already have the disease. It is very important that you take precautions to reduce the risk of COVID-19.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
