VIRUS:  World-first COVID-19 Vaccine Booster Study Launches in Greater Glasgow and Clyde 

Volunteers from West Dunbartonshire will be able to receive a third ‘booster’ COVID-19 vaccine.

Volunteers from NHS Greater Glasgow and Clyde will soon be able to receive a third ‘booster’ COVID-19 vaccine through a new clinical trial launching this week. NHSGGC are looking at recruiting 185 participants.

The Cov-Boost study, backed by £19.3 million of government funding through the Vaccines Taskforce, will be run at Glasgow Clinical Research Facilities – one of 16 sites across the UK. 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.

The study will be recruiting participants through the NHS COVID-19 Vaccine Research Registry, with vaccinations set to start from the beginning of June.

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 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 Julie Brittenden, Director of Research and Innovation, NHS Greater Glasgow and Clyde, said:

“Vaccines are an incredibly important tool for our fight against COVID-19. The team based at our Glasgow Clinical Research have been at the forefront of COVID research over the past year.

“Their work has been vital in developing the vaccines that are now being rolled out across the world. With this study we are supporting further research into the effectiveness of booster vaccines and hope our community will continue to support this vital research.

“Those wishing to take part should sign up to the NHS COVID-19 Vaccine Research Registry and we expect to welcome first patients onto the study in June.”

Professor Emma Thomson, Professor in Infectious Diseases at University of Glasgow Centre for Virus Research, and study lead in Glasgow, said:

“This study marks the next step forward in our efforts to understand how to best protect the population and inform future vaccine booster programmes.

“It is the first in the world to provide data on the impact of a third dose and will study seven different vaccines, providing important recommendations for the future.”

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.”
