1.  Who are we?

The Medicines and Healthcare products Regulatory Agency (the MHRA) is an Executive Agency of the Department of Health and Social Care (DHSC). The DHSC, together with its Executive Agencies is a single legal entity (or ‘controller’) for the purposes of data protection law. The Agency has three centres, MHRA, NIBSC and CPRD; and carries out controller functions for the personal data for which it isresponsible. These responsibilities include determining the purposes and means of processing the personal data.

You will find further information about the MHRA and DHSC on

2.  Why do we need your information?

The MHRA acts on behalf of the Ministers to protect and promote public health and patient safety by ensuring that medicines and medical devices meet appropriate standards of safety, quality, performance and effectiveness.

One of the ways in which we monitor products is through the Yellow Card scheme which is vital in helping the MHRA monitor the safety of all healthcare products in the UK to ensure they are acceptably safe for patients and those that use them. The Yellow Card Vaccine Monitor is an extension to our normal data collection under the Yellow Card scheme and is a platform designed to strengthen regulatory monitoring of the safety of COVID-19 vaccine/s, once approved for supply to the public. The Yellow Card Vaccine Monitor is required to supplement current passive monitoring methods to gain insights into the public’s experiences with COVID-19 vaccines compared to data from clinical trials. 

Background on the Yellow Card scheme

The Yellow Card scheme is the UK system for collecting and monitoring information on suspected safety concerns or incidents involving: medicines, medical devices and e-cigarette devices and liquids. The scheme is run by the MHRA and currently relies on voluntary reporting of suspected safety concerns or incidents by healthcare professionals and members of the public (patients, users, or carers). The purpose of the scheme is to provide an early warning that the safety of a product may require further investigation.

The Yellow Card website and Yellow Card app allow reports to be made for all medicines, including vaccines, blood factors and immunoglobulins, herbal medicines and homeopathic remedies, as well as all medical devices available on the UK market.

Our purpose is to investigate these reports and take any necessary regulatory action in line with our statutory duties.

We may occasionally conduct surveys of users of the Yellow Card Vaccine Monitor to help improve the user experience.

Yellow Card Vaccine Monitor data will hold information of value to public health and patient care; as a result, we may receive requests for the information contained in Yellow Card Vaccine Monitor submissions for academic research purposes that have potential scientific and / or significant public health value. However, the MHRA is conscious of the duty of confidentiality to patients and reporters. Therefore, all applications for research using Yellow Card Vaccine Monitor data will be reviewed and approved by an independent advisory Committee to ensure patient and reporter confidentiality is respected, and that information from Yellow Card Vaccine Monitor submissions which may indirectly identify individuals are used appropriately.

Whenever we process personal data, we will ensure that we comply with the data protection principles, so that your personal data is:

  • processed fairly, lawfully and transparently

  • processed for specific and legitimate purposes 

  • adequate, relevant and limited to what is necessary

  • accurate and kept up to date where necessary

  • kept in an identifiable form no longer than necessary for the purpose

  • processed securely – we will put in place appropriate technical and organisational measures to safeguard your information

3.  Our lawful basis

Our lawful basis for processing your personal data is UK GDPR Article 6(1)(e), which allows us to process personal data when this is necessary to perform our public tasks as a regulator.

Yellow Card Vaccine Monitor submissions require some information about the individual receiving a vaccination, the vaccinee. If you are registering yourself, the information will relate to you and include some special category personal data, such as information about your health or ethnicity. The lawful basis we rely on to process special category personal data are Article 9(2)(i) of the UK GDPR and Schedule 1 part 1(3) of the DPA, both of which enable us to process such information when it is necessary for reasons of the public interest in the area of public health.

Where we share Yellow Card Vaccine Monitor data for scientific or public health research purposes, we rely on UK GDPR Article 9(2)(j) as our lawful basis for processing special category personal data and Schedule 1 part 1(4) of the DPA. These bases permit us to process personal data for these purposes where it is in the public interest, subject to appropriate safeguards to protect your rights and freedoms.

4.  Who do we collect data from?

We collect data from anyone who accesses or registers with the Yellow Card Vaccine Monitor. We also collect data when a Yellow Card Vaccine Monitor submission is sent to us.

Reports related to side effects to medicines

UK reports (excluding Northern Ireland)

UK reports (excluding those from Northern Ireland) are subject to Human Medicines Regulations 2012, Part 11, and Schedule 12A, which requires MHRA to share all Yellow Card reports about potential side effects to medicines with the World Health Organisation’s Uppsala Monitoring Centre and pharmaceutical companies, however we remove all the person identifiers before sharing the reports. Post 31st December 2020 this legislation should be viewed in association with the Exceptions and modifications to the EU guidance on good pharmacovigilance practices that apply to UK marketing authorisation holders and the licensing authority.

Northern Ireland reports

Reports are identified as being from Northern Ireland (NI) if the reporter postcode begins with ‘BT’. According to the Northern Ireland Protocol, NI remain under European Pharmacovigilance Legislation, and therefore Directive 2010/84/EU and Regulation (EU) 1235/2010 apply, which requires MHRA to share all Yellow Card reports about potential side effects to medicines with the European Medicines Agency (EMA), however we remove all the person identifiers before sharing the reports. In line with the legislation, the EMA also makes this information available to the World Health Organisation’s Uppsala Monitoring Centre and pharmaceutical companies.

We may also share anonymised reports with other government departments or public health bodies where the report is relevant to the work of the department. This is shared to support safety monitoring activities and regulatory decisions.

We will also provide a copy of your report to your healthcare provider where you have requested this. 

10. Changes in our privacy policy

We will update this privacy policy when applicable to keep it up to date. If any change would result in us processing your personal data for a new purpose, we will inform you before we start using it in the new way.
