FRANKFURT (Reuters) - BioNTech expects that the experimental COVID-19 vaccine it is developing with Pfizer can be stored at refrigerator temperatures for at least two weeks, seeking to allay concerns that the compound may have to be deep-frozen.
Speaking at an online media briefing on the purchase of an additional German production site, Chief Executive Ugur Sahin said tests have recently confirmed the genetic compound remains stable at 2 to 8 degrees Celsius for five days but he expects storability at those conditions to be two weeks or longer.
He added that a good vaccine should have an efficacy of at least 70% to 75% for it to quell the pandemic and that was also the yardstick that BioNTech had set itself.
