when will the new covid vaccine be available in 2023

The new COVID-19 vaccines for 2023 were made available primarily during the year with updated formulas targeting specific Omicron variants. By late 2023, vaccines targeting the XBB lineage of Omicron were introduced, and the Moderna and Pfizer-BioNTech vaccines have been updated repeatedly to keep pace with emerging variants. These vaccines have been available to different age groups since 2023, with continuing updates into 2024 and 2025. For example, in 2023, monovalent shots for XBB were introduced, followed by further updated shots in 2024-2025 targeting KP.2 strain. Specifically for 2023, updated COVID vaccines were available and recommended for use by various age groups, including children from 6 months old and older adults, with doses tailored by age and health condition. The vaccines from Pfizer-BioNTech and Moderna continued to be accessible for emergency use and full approval with modifications to better match circulating variants. The Novavax vaccine also had an update in late 2024, but the 2023 version is no longer available as doses expired. In summary, new COVID vaccines in 2023 were available throughout the year, with ongoing updates that extend into 2024 and beyond to adapt to the evolving virus variants, and the vaccines are recommended for wide use across age groups to provide better protection against current strains of the virus.
