Mark Lowcock, the United Nations’ humanitarian chief has warned that poorer countries unlikely to gain substantial access to Covid-19 vaccines until the latter half of next year, will leave wealthier European countries vulnerable to new waves of infection for years. The Gaurdian reports that Lowcock said it was understandable that countries that had financed the research and manufacture of vaccines would seek to gain first access, but warned that vaccine nationalism would prove to be counterproductive and self-defeating, warning that the virus can get everywhere”. “It is going to be true that nowhere is safe until everyone is safe because it is a globalised world,” Lowcock warned.
