BOSTON — BioNTech CEO Uğur Şahin had been in marathon meetings since he arrived in this city three days earlier, but if his energy had flagged it didn’t show. The clock had not even struck 8 a.m., and there was Şahin, in front of a table at the Four Seasons strewn with continental breakfast, deep in discussion with HIV expert Bruce Walker of the Ragon Institute.
Before Walker left, Şahin asked a reporter, newly arrived, to snap a photo of them to commemorate the moment.
