Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what comparative assessment he has made of the implications for safety of NHS trusts waiting (a) 12 and (b) three weeks to give the second dose of the Pfizer vaccine to frontline staff who are caring for covid-19 patients.

There is insufficient data to undertake a formal comparative assessment of the implications for safety of different dose intervals with the Pfizer-BioNTech vaccine.
