What is the VAC4COVID Study?

VAC4COVID was 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. The aim of the study was to learn about how people receiving COVID-19 vaccinations in the UK felt before and after vaccination.

The study was open to UK adults aged 18 and older. Participating adults could also submit information on behalf of dependent children under 18 years of age.

This study closed on January 31st 2023.

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.
