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 level of risk of covid-19 transmission and infection in the context of a reduction of efficacy of the booster vaccine to between 40 and 50 per cent 10 weeks post-vaccination.
The UK Health Security Agency (UKHSA) has not made a specific assessment. The UKHSA publishes current estimates of the effectiveness of vaccines against circulating variants and supplies this evidence to modelling groups as it becomes available.
