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 efficacy of the (a) Pfizer and (b) Moderna vaccine after 12 weeks; and if he will publish those assessments.

There is no data on the efficacy of the Moderna or Pfizer/BioNTech vaccine 12 weeks after the first dose. Given the high effectiveness and durability of responses to the first dose seen in United Kingdom data, it is not expected that protection will reduce rapidly after 12 weeks.
