IMPORTANT SAFETY INFORMATION
You or your child should not get SPIKEVAX® if you had a severe allergic reaction after a previous dose of SPIKEVAX or any Moderna COVID-19 vaccine or to any ingredient in these vaccines.
What are the risks of SPIKEVAX?
There is a very small chance that SPIKEVAX could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose of SPIKEVAX. For this reason, the healthcare provider may ask you or your child to stay for a short time at the place where you or your child received your vaccine. Signs of a severe allergic reaction can include:
- Trouble breathing
- Swelling of your face and throat
- A fast heartbeat
- A rash all over your body
- Dizziness and weakness
- Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received mRNA COVID-19 vaccines. Myocarditis and pericarditis following mRNA COVID-19 vaccines have occurred most commonly in males 12 years through 24 years of age. You should seek medical attention right away if you or your child has any of the following symptoms after receiving Spikevax, particularly during the 2 weeks after receiving a dose of the vaccine: chest pain, shortness of breath, feelings of having a fast-beating, fluttering, or pounding heart. Additional symptoms in children may include fainting, irritability, poor feeding, lack of energy, vomiting, pain in the abdomen, or cool, pale skin.
Other side effects that have been reported include:
- Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm of the injection or in the groin, swelling (hardness), and redness
- General side effects: fatigue, headache, muscle pain, joint pain, chills, nausea and vomiting, fever, rash, irritability/crying, sleepiness, and loss of appetite.
- Fainting and febrile seizures (convulsions during a fever) were also reported
Tell the healthcare provider about all of your or your child’s medical conditions, including if you or your child:
- have any allergies
- had a severe allergic reaction after receiving a previous dose of any COVID-19 vaccine
- have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
- have a fever
- have a bleeding disorder or are on a blood thinner
