Wall Street Journal: Sinovac’s Covid-19 Vaccine Is 78% Effective in Brazil Late-Stage Trials

From the article:

Prashant Yadav, a global health specialist at Washington-based think tank Center for Global Development, said 78% is a high enough rate for many developing countries to consider using the vaccine and potentially good enough for the World Health Organization to consider incorporating CoronaVac into its global distribution system. 

“There are a large number of developing countries that haven’t been able to secure supplies,” he said. “This could become a very viable option for them.”
