Question to the Department of Health and Social Care:

To ask Her Majesty's Government why they are introducing a requirement for proof of vaccination in some indoor spaces from September and not immediately; and what assessment they have made about (1) infection levels, and (2) transmissibility, to inform this decision.

Starting this requirement in September allows for all adults in the United Kingdom to be offered vaccination. Infection rates for fully vaccinated in those under 65 years old are three times lower than in the unvaccinated. There is now significant evidence that vaccines are effective at preventing infection and therefore will prevent transmission. There is also further evidence that even if vaccinated individuals become infected there is a reduced risk of transmission to others of approximately 40-45% after one dose.
