Side effects of the COVID-19 vaccines, similar to other routine vaccinations, are typically mild and subside in a few days. Common experiences include soreness and swelling in the injected arm or leg, chills, joint pain, swollen lymph nodes, irritability, loss of appetite, fatigue, headaches, and a mild fever.

The risk of a child having a serious adverse reaction to the COVID-19 vaccine is very low. One rare complication that has been linked to the COVID-19 vaccine is myocarditis (inflammation of the heart). Data demonstrates a higher risk for such inflammation amongst male children and adolescents. However, reports of these complications are rare. The risk of developing myocarditis after a COVID-19 infection is much higher than the risk of developing myocarditis after the vaccine.

If you have questions about COVID-19 vaccines, myocarditis, or how to protect your children from COVID-19, speak to your healthcare provider or pediatrician.
