Coronavirus: fuller picture of Chinese vaccine data but WHO group finds figures lacking for over 60s

Assessments of Chinese-developed Covid-19 vaccines posted by the World Health Organization give a fuller picture of their safety and efficacy. But they also expose limits of the data for older and at-risk groups.

The WHO released the information about Covid-19 vaccines by Sinopharm and Sinovac Biotech as it continues to evaluate the candidates for emergency-use licensing. A decision on whether they will receive the internationally recognised stamp of approval is expected this week.
