SINGAPORE - Experts are calling for an increase in local production of Covid-19 vaccines, especially in developing nations, and greater transparency between governments and pharmaceutical companies in their orders and distribution. They have also urged the World Health Organisation (WHO) to reform its governance system to involve not just states, but also other key players. Developing nations are falling behind rich nations in vaccinating their population, often due to a scarcity of doses. Richer states have taken up more than half of the world's available vaccines. Some have even hoarded the vaccines while poorer countries reel under the pandemic. Speaking at a webinar by the Australian National University on Thursday (June 3), Professor Tikki Pangestu of the Yong Loo Lin School of Medicine at the National University of Singapore said one way to solve the vaccine shortage is for developing nations that are manufacturing their own vaccines to ramp up production.
