Агентство публикует еженедельные отчёты по ситуации с вакцинацией в стране. Вот последний на данный момент отчёт (43 неделя) - https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1029606/Vaccine-surveillance-report-week-43.pdf
В отчёте по сравнению с предыдущими выпусками появилась новая оговорка:
The vaccination status of cases, inpatients and deaths is not an appropriate method to assess vaccine effectiveness because of differences in risk, behaviour and testing in the vaccinated and unvaccinated populations.
