A coronavirus vaccine booster study has been launched in the UK to test the effects of an extra dose.

The trial, hailed by the UK government as a world first for the COVID-19 vaccine, will evaluate the Oxford / AstraZeneca, BioNTech / Pfizer, Moderna, Novavax, Valneva, Johnson & Johnson and CureVac vaccines as potential booster vaccines that would be administered. 10 to 12 weeks after the administration of a second dose as part of the vaccination campaign underway in the country. The recall could be a different brand than the one originally used.

Drugmakers are already conducting studies on the response to booster shots, but the UK trial will specifically look at the immune response of different brands of vaccines side by side.

The study comes as governments debate how to reopen in an environment concerned about the spread of new worrisome variants. In a statement Wednesday, the UK Department of Health said the government was already preparing for a clinical needs-based recall program, with details to be released “in due course”.
