Everyone 6 months and older should receive a COVID-19 Vaccine
COVID-19 vaccines are safe and effective. The safety of COVID-19 vaccines has been rigorously monitored and evaluated since their emergency use authorization (EUA) in December 2020. The updated mRNA COVID-19 vaccines for 2023-2024 are manufactured using a similar process to the previous vaccines.
As with all vaccines authorized or approved for use in the U.S., CDC, FDA and other federal agencies will continue to closely monitor the safety of the updated 2023-2024 COVID-19 vaccines using multiple vaccine safety monitoring systems and will share information with the public as it becomes available.
Common Side Effects
Some people have side effects after COVID-19 vaccination, while others might have no side effects. Side effects tend to be mild, such as soreness at the injection site and fever, and should go away within a few days. Learn more about common side effects after COVID-19 vaccination.
Adverse Events (Health Problems) Are Rare
In rare cases, people have experienced more significant adverse events after COVID-19 vaccination. Any health problem that happens after vaccination is considered an adverse event. An adverse event can be caused by the vaccine or can be caused by a coincidental event not related to the vaccine, such as an unrelated fever, that happened following vaccination.
Benefits of COVID-19 Vaccination Outweigh the Risks
COVID-19 vaccination continues to be the best way to protect against serious illness. The benefits of COVID-19 vaccination outweigh the known and potential risks. CDC, the U.S. Food and Drug Administration (FDA), and other federal agencies continue to monitor the safety of the updated COVID-19 vaccines and will share information with the public as it becomes available.
