What is the VAC4COVID Study?
VAC4COVID is a UK-wide online study, run by MEMO Research at the University of Dundee, to track COVID-19 vaccines and provide data to support vaccine monitoring. Mass COVID-19 vaccination programmes are now underway in response to the worldwide pandemic. All licensed or authorised vaccines have already been tested extensively for effectiveness and safety in large clinical trials. As with every new medicine, governments and researchers will keep watching how COVID-19 vaccines are working once they are being used in the wider population. This is the aim of this study and is an important part of how medicines and vaccines are regulated.
- Open to everyone in the UK aged 18 years of age or older.
- Ability to submit data on behalf of your children, if they are under the age of 18.
- You can sign up before or after vaccination, and also if you are not vaccinated.
- We will keep in touch with you by email to ask you about COVID-19 vaccinations and any changes in your health.
- If you suffer any health problems before or after vaccination, telling us about them will help us to learn more.
Vaccines are crucial for reducing COVID-19 and the harm it causes to health. By taking part in the VAC4COVID Study you can help us understand how people do after vaccination, and support public confidence in COVID-19 vaccines.
Health information provided by participants will be verified (where required) with health professionals and medical records; this is to ensure that all the information we collect is valid. We will report our findings to the Medicines and Healthcare Regulatory Authority (MHRA) to help them make informed decisions about vaccine programmes.

About Us
Led by Prof. Tom MacDonald and Prof. Isla Mackenzie, MEMO Research has delivered high quality research for over 20 years with two key themes: observational studies and clinical trials. Early on, MEMO developed ways to study prescribing in primary care, allowing a range of studies into the safety of commonly prescribed drugs. Since that time, we have undertaken clinical trials to further understand the safety and use of medicines.
Experience of many types of research helps us to continue innovating and delivering studies which can improve healthcare globally.
