The most common reactions following COVID-19 vaccines are pain, redness, and swelling where the shot was given, and headache, fever, muscle aches, chills, or fatigue. Almost 700 million doses of COVID-19 vaccines have been administered in the United States to date, and monitoring in multiple safety systems has established their favorable safety profile. CDC closely monitors the safety of COVID-19 vaccines. In preclinical studies, Pfizer’s updated COVID-19 vaccine also produced strong immune responses to XBB.1.5. These data signal that the updated 2023-2024 COVID-19 vaccine likely can provide strong protection against COVID-19 during this fall and winter virus season. Their antibody responses after vaccination were about 17-times higher against XBB 1.5 and about 10-times higher against BA.2.86 ( a rare new variant that CDC is closely monitoring) compared to before vaccination. They also had an overall boost in COVID-19 immunity that may have waned since their last vaccination or infection.

People vaccinated with Moderna’s updated COVID-19 vaccine, which includes a component that corresponds to the XBB lineage of the Omicron variant, showed a strong immune response against some of the variants that are common now (XBB.1.5, EG.5.1, and FL.1.5.1). Immune responses to the updated COVID-19 vaccine. Scientific Understanding of the updated COVID-19 vaccines: Uninsured children and uninsured adults also have access through the Vaccine for Children Program and Bridge Access Program, respectively. The vaccines are covered by insurance, including private insurance, Medicare plans, and Medicaid plans.In one study, the risk of cardiac complications, including myocarditis, in males 12-17 years old was 1.8 – 5.6 times higher after COVID-19 infection than after COVID-19 vaccination.Serious reactions after COVID-19 vaccination are rare. The benefits of COVID-19 vaccination continue to outweigh any potential risks.The updated vaccines should work well against currently circulating variants of COVID-19, including BA.2.86, and continue to be the best way to protect yourself against severe disease.

In addition, healthy children and adults can still experience severe disease.

Older adults and persons with weakened immune systems are at greatest risk for hospitalization and death.

Updated COVID-19 vaccines are recommended for everyone 6 months and older and will be available by the end of this week at most places you would normally go to get your vaccines.
