Most people do not experience serious side effects from COVID-19 vaccines.

The most common side effect is that after receiving the vaccine, your arm may be sore, red or warm to the touch. These symptoms usually go away on their own within a week. Other side effects may include a headache, fever, chills or muscle aches – especially after receiving the second shot. These side effects are considered normal, and a sign that the COVID-19 vaccine is working to protect you. Like adults, the most common side effects for adolescents are muscle soreness and fever.

“Those mild symptoms of feeling achy, (and) maybe some low-grade fever are really your immune system telling you that the vaccine is doing exactly what we want it do,” Dr. Gay says. “We want your immune system to respond to the vaccine (and) produce antibodies such that if and when someone is exposed to the coronavirus, those antibodies are present and can recognize, (and) bind to the coronavirus, and either prevent infection or make the infection less severe.”

So, the vaccine can make a person feel like they are sick, but symptoms almost always last just one to two days.
