Indonesia has ordered 125m doses from Sinovac and began its vaccination campaign with the president, Joko Widodo, receiving a jab live on television. The Philippines has signed a deal for 25m doses, while Myanmar has been promised a donation of vaccines by China. Thailand, whose biggest supplier is AstraZeneca, has ordered 2m Sinovac doses and hopes to start administering the first batch next month. Elsewhere, Turkey began administering the Sinovac vaccine to healthcare workers on Thursday after approving it for emergency use.
Health experts fear public trust has been undermined by a series of conflicting efficacy findings, and say a lack of data is hampering their understanding of how the vaccine works.
