New COVID-19 boosters, based on updated formulas like the monovalent JN.1-lineage vaccine for the 2025-2026 formula, are expected to be available beginning in fall 2025. Seasonal COVID-19 booster vaccines are offered in spring and autumn each year, with the next boosters planned for autumn 2025, targeting those most at risk of severe illness. In the UK and the US, these updated vaccines are recommended especially for older adults, immunocompromised individuals, and other high-risk groups. Vaccines for the 2024-2025 season are currently available, with the updated 2025-2026 vaccines expected in the fall 2025 respiratory illness season. People eligible for these boosters can typically receive them about six months after their last dose, with some flexibility based on individual conditions.

In summary:

• Updated boosters for 2025-2026 available starting fall 2025.
• Seasonal boosters typically in spring and autumn.
• Targeted to high-risk groups such as elderly and immunocompromised.
• Availability and recommendations may vary by region but generally align for vulnerable populations.
