Geneva [Switzerland], March 10 (ANI/Sputnik): World Trade Organization (WTO) Director-General Ngozi Okonjo-Iweala has called on pharmaceutical companies to scale up the production of coronavirus vaccines in developing countries to overcome supply shortage.

"Director-General Ngozi Okonjo-Iweala on 9 March called on COVID-19 vaccine manufacturers to do more to ramp up production in developing countries to combat the vaccine supply shortage that is excluding many lower-income nations from access. In remarks to an event hosted by the UK think tank Chatham House, she said cooperation on trade, and action at the WTO, would help accelerate vaccine scale-up," the WTO said in a press release late on Tuesday.
