Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment he has made of the potential merits of collecting data on the (a) number of people who have contracted covid-19 after receiving two doses of a vaccine and (b) average length of stay for those double-vaccinated people who have been admitted to hospital.

Public Health England monitors the number of people who have tested positive for COVID-19 and whether they have received one or two doses of the vaccination. This data is used to calculate vaccine effectiveness estimates which are available at the following link:

NHS Digital collects data on the number of people who have contracted COVID-19, patients who have received one or two doses of a vaccine and hospital data that can be used to calculate average length of stay. These three datasets can be linked where possible to track patient outcomes for vaccinated people.
