Sparky gives you only part of the story. Here is the rest of the story.
"According to the U.S. Food and Drug Administration (FDA), the bivalent Moderna and Pfizer-BioNTech COVID-19 vaccines are no longer authorized for use in the United States 123. However, the FDA has approved and authorized for emergency use updated COVID-19 vaccines formulated to more closely target currently circulating variants and to provide better protection against serious consequences of COVID-19, including hospitalization and death 1. The updated mRNA vaccines for 2023-2024 manufactured by ModernaTX Inc. and Pfizer Inc. have been updated to include a monovalent (single) component that corresponds to the Omicron variant XBB.1.5 1. The FDA is confident in the safety and effectiveness of these updated vaccines and the agency’s benefit-risk assessment demonstrates that the benefits of these vaccines for individuals 6 months of age and older outweigh their risks 1. Individuals who receive an updated mRNA COVID-19 vaccine may experience similar side effects as those reported by individuals who previously received mRNA COVID-19 vaccines as described in the respective prescribing information or fact sheets 1. The updated vaccines are expected to provide good protection against COVID-19 from the currently circulating variants 1."
