What to Expect After Getting A COVID-19 Vaccine
By now, approved vaccines have been tested in tens of thousands of people and over 15 million Americans have received one or two doses. Many people who get the vaccines have no side effects. Some people who get the vaccines do get minor side effects that may affect their ability to do daily activities, but these symptoms usually go away on their own within a week. Common side effects are:
Soreness or pain at the injection site;
Fatigue
Fever or chill
Headache
These side effects are a sign that the immune system is working to build protection to disease. In most cases, discomfort from fever or pain is normal.
CDC recommends that if you have pain or discomfort, talk to your doctor about taking over-the-counter medicine, such as ibuprofen, aspirin, antihistamines, or acetaminophen, for any pain and discomfort you may experience after getting vaccinated. If your side effects are worrying you or do not seem to be going away after a few days, contact your doctor.
If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911. Learn more about COVID-19 vaccines and rare severe allergic reactions.
We do not know what the long term side effects from the vaccine is, but we do know that many people who get infected with COVID-19 are having ongoing health problems.. That is why safety monitoring will continue. CDC has an independent group of experts that continue to review safety data as it comes in and provides regular safety updates.
