Intermediate Analysis of Chinese Vaccines against Coronavirus COVID-19 from companies SINOVAC and SINOPHARM has shown their safety and efficiency, but specialists require additional data. This view was the strategic advisory group of experts (Sage) WHO.
“Sage studied the provided data: both vaccines demonstrated safety and good efficacy against coronavirus symptoms,” the interfax quotes the expert statement.
It is noted that specialists lack data on the action of vaccines on older people and on people with chronic diseases. “Research after the introduction of vaccine on its effectiveness and security is required to clarify its impact on these subgroups of the population,” added to Sage.
