Geneva:WHO Director-General Tedros Adhanom Ghebreyesus has called for "fair allocation" of a COVID-19 vaccine after drugmakers Pfizer and BioNTech this week said that their vaccine candidate was found to be more than 90 per cent effective in preventing the disease in an interim analysis of data.
Addressing the member states at the 73rd World Health Assembly on Tuesday, the WHO chief said that the UN health agency welcomes Pfizer's "promising news" and expect additional effective vaccines in near future along with advances in testing and therapeutics.
Based on current projections, Pfizer and BioNTech expect to produce globally up to 50 million vaccine doses this year and up to 1.3 billion doses in 2021.

The issue of challenges of distributing a potential vaccine such as the one being developed by Pfizer and BioNTech was also raised by Matshidiso Moeti, WHO's Regional Director for Africa.
"The exciting news yesterday (Monday) of a possible effective vaccine becoming available presages significant cold chains challenges for African countries by the type of vaccine that that is. Which will need to be factored into the support to be provided," Moeti said.
