The Spring 2025 booster campaign is progressing well, with just over 2.7 million doses administered in the first four weeks in England.

Number of doses per week by vaccination campaign in England: Week ending Mar 7, 2022 - Apr 27, 2025

Eligibility for the Spring Booster campaigns is the same for each year so are comparable, whereas the Autumn 2022 campaign was offered to a larger cohort than the following Autumn campaigns so should not be compared to these years.
