The British government will be testing to see if a third dose of a coronavirus vaccine will provide additional protection against COVID-19 and its variants.
The COV-Boost, as it is called, will test the seven vaccines already in existence to see which could be used in any upcoming vaccination program later in the year. The seven vaccines include Pfizer, AstraZeneca, Moderna, Novavax, Johnson & Johnson, Valneva, and CureVac.
About 3,000 people over the age of 30 will be tested at 18 sites in the United Kingdom.
British Health Secretary Matt Hancock says the data “from this world-first clinical trial will help shape the plans for our booster program later this year.”
