Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, on what date NHS England informed patients receiving the Oxford-AstraZeneca Covid-19 vaccine that there were safety risks of vaccine-induced thrombosis with thrombocytopenia associated with the vaccine.

To ensure informed consent was given by patients who received the AstraZeneca COVID-19 vaccine, all vaccination sites were instructed to follow consent guidance in line with the recommendations set out in chapter two of the UK Health Security Agency Green Book on vaccinations and immunisations.

Healthcare organisations administering any COVID-19 vaccinations are responsible for drawing up their own policies for obtaining informed consent, and health professionals overseeing or administering COVID-19 vaccines are responsible for ensuring that valid consent has been obtained. This would normally involve a discussion with the clinician prior to the administration of the vaccine, and individuals will also have had access to guides and patient information leaflets which provided details about the vaccine, how it is administered, possible side effects, and other warnings and precautions to take.

Regarding the very rare adverse events of concurrent thrombosis and thrombocytopenia associated with the AstraZeneca COVID-19 vaccine, NHS England notified healthcare organisations administering the COVID-19 vaccinations immediately following the updated advice from the independent Joint Committee on Vaccination and Immunisation published on 7 April 2021, and then again following updated advice on 7 May 2021. In these updates, sent via system letters, NHS England set out the next steps for healthcare organisations and clinicians, including on the consent process.
