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 to the potential merits of T-Cell Immunity tests in informing a person's individual immunity to covid-19.

T-cell tests are utilised in specific groups for clinical or research purposes including the Protective Immunity from T-Cells in Healthcare workers, the Vivaldi study in Adult Social Care home residents and staff, and in clinically assessing those who may be immunocompromised. Work is ongoing to compare, contrast and standardise cellular assays for larger scale screening.
