Southampton is taking part in a "world-first" trial.
HAMPSHIRE is spearheading a world-first trial to identify the most effective booster vaccines in the battle against Covid-19.
A new government-funded initiative will determine the immune responses triggered by each of the seven vaccines developed in a bid to defeat the killer virus.
The trial will be led by University Hospital Southampton NHS Foundation Trust.
A trust spokesperson said: "Volunteers from Southampton, Portsmouth and Bournemouth will soon be able to receive a third ‘booster’ vaccine through a new clinical trial launching this week.
"The study, backed by £19.3m of government funding through the Vaccines Taskforce, will be run at University Hospital Southampton, University Hospitals Dorset and the Portsmouth Research Hub (Portsmouth Hospitals).
