The Spring 2025 booster campaign is progressing well, with just under 3.3 million doses administered in the first six weeks in England. 

Number of doses per week by vaccination campaign in England: Week ending Mar 7, 2022 - May 11, 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.
