He said those hoping for a breakthrough to end the pandemic would be disappointed, with some vaccines likely to reduce the risk of Covid-1coronairus9 infection by only 30%.
"None of the trials currently under way are designed to detect a reduction in any serious outcome such as hospital admissions, use of intensive care, or deaths," he said.
"Nor are the vaccines being studied to determine whether they can interrupt transmission of the virus." ■
