Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, how many cases of covid-19 vaccine-induced thrombosis and thrombocytopenia were reported to Public Health England using the reporting link contained within the 7 April 2021 Guidance from the Expert Haematology Panel; and how many of these reports related to events that took place before April 2021.

This data collection was established to support the work of the Medicines and Healthcare products Regulatory Agency. Whilst information on reported cases of COVID-19 vaccine induced thrombosis and thrombocytopaenia was collected by Public Health England, reporting was not mandatory or part of an official surveillance system and the data are not centrally validated.
