May.07 -- The European Federation of Pharmaceutical Industries and Associations says that President Joe Biden's support for international talks on waiving patent protections for Covid-19 vaccines could result in a fall in quality if raw materials are diverted away from approved production facilities. "If you suddenly have a diversion towards other manufacturing sites that maybe are less efficient, less productive, means that the quality is less good, maybe you suddenly have counterfeits," Nathalie Moll, EFPIA's director general, said on Bloomberg Television.
