LONDON — One of the scientists behind the experimental coronavirus vaccine developed by BioNTech and Pfizer says he's confident that it could halve the transmission of the virus, resulting in a “dramatic” curb of the virus’ spread.

The chief executive of Germany’s BioNTech said Sunday that it is “absolutely essential” to have a high vaccination rate before next autumn to ensure a return to normal life next winter. He says if everything continues to go well, deliveries of the vaccine will start late this year or early next year.
