J&J may follow ImmunityBio’s South African Covid booster shot trial
(Bloomberg) – Talks are underway with Johnson & Johnson about running a booster trial in South Africa after the company's Covid-19 vaccine was used in a mass trial of almost half a million health workers in the country.
The trial would include participants from that study, known as Sisonke, and could possibly start in October, according to Glenda Gray, who is co-lead of the mass trial. It would add to a booster study in the country using ImmunityBio's shot that has already started.
South Africa, where scientists believe that about a quarter of a million people have died of Covid-19, has hosted vaccine trials for companies including Novavax, Pfizer, AstraZeneca and J&J. The country is currently exiting its third wave of infections with another resurgence expected later this year.
