A UK Health Security Agency annual report published on 13 August 2026 found about 50% fewer infants under 6 months admitted to intensive care or higher dependency units with confirmed RSV chest infection in England in 2025-26 than in 2024-25. The figures cover the same 20 NHS trusts taking part in surveillance: 63 admissions in 2025-26, against 131 the previous season.

The report covers the first full year of the NHS RSV maternal vaccination programme, which began in September 2024. It states that 61.7% of women giving birth received an RSV vaccine in the 12 months from March 2025 to February 2026. UKHSA said many thousands of babies remain at risk, since around 60% of women giving birth each month are vaccinated.

Peak weekly infant bronchiolitis A&E attendances in England were lower than in previous seasons, and the peak season was shorter. The report also cites a sustained reduction of over 40% in RSV-related hospitalisation rates among eligible adults aged 75 to 80, with 65% of eligible older adults vaccinated by the end of May 2026.
