The risk emanating from the Biontech vaccine, whose expiry date had passed a few days, was “very low to non-existent”: Liam Klages, head of the Ebersberg vaccination center, has now received this information from the company Biontech. He had asked there because 1,800 people in the Ebersberg vaccination center and its Poinger branch office had received Biontech vaccine between January 4th and 6th, the expiry date of which had been exceeded by four to six days.
As the spokesman for Biontech reports, the Comirnaty vaccine is stable for 45 days when stored at two to eight degrees – i.e. 14 days longer than the officially printed expiry date. Studies carried out jointly with partner Pfizer have shown that.
