New Delhi: The World Health Organization (WHO) plans to approve several corona vaccines in the coming weeks and months. A document published on Wednesday shows that WHO aims for rapid rollouts in poorer countries. COVAX, a global scheme co-led by the WHO, aims to deliver at least 2 billion COVID-19 doses across the world this year, with at least 1.3 billion to poorer countries. But it has so far struggled to secure enough shots due to a shortage of funds, while wealthy nations have booked large volumes of vaccines for themselves. Some poorer countries rely mostly on WHO authorisations as they have limited regulatory capacity. Therefore, WHO is plannin to approve several corona vaccines in the coming weeks and months. According to the document, The COVID-19 vaccine developed by AstraZeneca and manufactured by the Serum Institute of India (SII) could be authorised by the WHO in January or February, the document says. The same vaccine produced in South Korea by SK Bioscience could be approved by the U.N. agency in the second half of February.
