Britain's GSK and South Korea's SK Bioscience said on Tuesday the drugmakers have begun a late-stage trial of their COVID-19 vaccine candidate to assess immune response when compared with AstraZeneca's approved shot.
The trial will enrol around 4,000 candidates globally and test SK's COVID-19 vaccine candidate, GBP510, in combination with GSK's vaccine booster following positive early-stage data earlier this month.
Results from the GSK-SK study are expected in the first half next year, and the vaccine will be supplied worldwide through the World Health Organization-led vaccine sharing programme COVAX if approved, the companies said.
