A Canadian vaccine researcher says he believes that Chinese political machinations ended a vaccine partnership last summer. Dr. Scott Halperin, the director of the Canadian Centre for Vaccinology, made the accusation Thursday to the Special Committee on Canada-China Relations. The partnership was originally planned to be between China’s CanSino Biologics and the Canadian Centre for Vaccinology at Dalhousie University in Nova Scotia. CanSino had been given a licence by the National Research Council to use a Canadian biological product as part of a COVID-19 vaccine. China blocked shipments it was supposed to send to Dalhousie researchers by the end of May 2020 to start human trials. Halperin said he was initially told it was due to bureaucratic issues such as paperwork. By August, he said, it became clear that the Chinese government had no desire for the vaccine to leave the country.
