Three doses of a Covid vaccine may not be able to curb the rapid spread of the highly transmissible Omicron variant of Covid, warned Ugur Sahin, CEO of Germany-based BioNTech.

“We must be aware that even triple-vaccinated are likely to transmit the disease. It is obvious we are far from 95 per cent effectiveness that we obtained against the initial virus,” Euronews quoted Sahin as saying to the French daily Le Monde on Monday. BioNTech partnered with US drugmaker Pfizer to develop the two-dose revolutionary Covid jab, based on mRNA technology.
