"Last season, those who received a 2022-2023 COVID-19 vaccine saw greater protection against illness and hospitalization than those who did not receive a 2022-2023 vaccine. To date, hundreds of millions of people have safely received a COVID-19 vaccine under the most intense safety monitoring in U.S. history."

"All viruses mutate, so while none of the variants circulating right now are exact matches to the vaccine, they’re all closely related to the XBB.1.5 strain it’s based on. Studies have shown that antibodies generated to the XBB.1.5 variant cross-react well with the EG.5 variant. The same is true for the FL.1.5.1 variant, which has been increasing in prevalence since mid-summer."
