University Hospital Southampton NHS Foundation Trust’s COV-Boost vaccine trial is studying the use of seven different COVID-19 vaccines when given as a third dose.

This study is being led by University Hospital Southampton NHS Foundation Trust (Chief Investigator Professor Saul Faust), and delivered by a network of trial sites across the UK. The study is funded by the Vaccine Task Force and the National Institute for Health Research (NIHR).

Our researchers are working hard to get the results available to inform UK immunisation policy as quickly as possible.  We ask that the media do not continue to contact researchers while this critical work is underway, and to use the media contact form for press enquiries.
