Southampton leads world-first COVID-19 vaccine booster study
New government-funded clinical trial looking at different COVID-19 ‘booster’ vaccines launched today in the UK
Study will determine immune responses and reactogenicity from third dose of one of seven different vaccines
Initial results expected in September to help inform potential booster programme

Volunteers from Southampton, Portsmouth and Bournemouth will soon be able to receive a third ‘booster’ COVID-19 vaccine through a new clinical trial launching this week, the Health Secretary has announced.
The Cov-Boost study, backed by £19.3 million of government funding through the Vaccines Taskforce, will be run at University Hospital Southampton, University Hospitals Dorset and the Portsmouth Research Hub (Portsmouth Hospitals), and is being led by University Hospital Southampton. It will be the first in the world to provide vital data on the impact of a third dose on patients’ immune responses.
It will give scientists from around the world and the experts behind the UK’s COVID-19 vaccination programme a better idea of how effective a booster of each vaccine is in protecting the individual from the virus.
The initial findings, expected in September, will help inform decisions by the Joint Committee on Vaccination and Immunisation (JCVI) on any potential booster programme from autumn this year, ensuring the country’s most vulnerable are given the strongest possible protection over the winter period.
The trial will look at seven different COVID-19 vaccines as potential boosters, given at least 10 to 12 weeks after a second dose as part of the ongoing vaccination programme. One booster will be provided to each volunteer and could be a different brand to the one they were originally vaccinated with.
Vaccines being trialled include Oxford/AstraZeneca, Pfizer/BioNTech, Moderna, Novavax, Valneva, Janssen and Curevac, as well as a control group. The trial has received ethics approval by the NHS Research Ethics Committee, as well as approval from the Medicines and Healthcare products Regulatory Agency.
Participants will be adults aged 30 years or older and will include those immunised early on in the vaccination programme - for example, adults aged 75 and over or health and care workers.
The study will take place at 16 NIHR-supported sites across the UK, and will include a total of 2,886 patients. All participants will be monitored throughout the study for any potential side effects and will have bloods taken to measure their immune responses at days 28, 84, 308 and 365, with a small number having additional blood tests at other times.
All sites will have an electronic diary for all participants that will send alerts to the team in real time if needed and a 24-hour emergency phone to a doctor on the study, who can provide further clinical advice.
All the trial sites are working on ways of including people in research from a wide variety of backgrounds and individuals from ethnic minorities are encouraged to apply.
The government is preparing for a potential booster programme based on clinical need and will publish further details in due course. The final policy will be informed by advice from the JCVI and take into account the results of clinical trials.
Professor Saul Faust, Chief Investigator and Director of NIHR Southampton Clinical Research Facility, said:
“This trial will give the Joint Committee on Vaccination and Immunisation the important data to inform their recommendations of how to protect the population against any future wave.
“It is fantastic that so many people across the country have taken part in vaccine trials up to now so that we can be in a position to study the effects of boosters, and we hope that as many people as possible over the age of 30 who received their first dose early in the NHS programme will be able to take part.”
Rt Hon Matt Hancock MP, Health and Social Care Secretary, said:
“We will do everything we can to future-proof this country from pandemics and other threats to our health security, and the data from this world-first clinical trial will help shape the plans for our booster programme later this year.
“I urge everyone who has had both doses of a COVID-19 vaccine, and is eligible, to sign up for this study and play a part in protecting the most vulnerable people in this country and around the world for months and years to come.”
Professor Andrew Ustianowski, National Clinical Lead for the UK NIHR COVID Vaccine Research Programme, said:
"Throughout the pandemic, the National Institute for Health Research, the NHS and all of our research partners have helped to rollout vital studies to help us learn how to treat COVID-19 and develop effective vaccines. The Cov-Boost study marks the next step forward in our efforts of understanding how to best protect the population and inform future vaccine booster programmes.
"Since the launch of the NHS COVID-19 Vaccine Research Registry, thousands of volunteers have been recruited to key vaccine studies, and we are confident we can call upon our nearly half a million strong community to help recruitment to this important trial."
Minister for COVID-19 Vaccine Deployment Nadhim Zahawi, said:
“Having taken part in a COVID-19 vaccine clinical trial myself, I would encourage everyone eligible to volunteer – whatever your religion, ethnicity or background, it’s a fantastic opportunity to get involved with such an historic initiative.”
