Study Shows Sinopharm COVID-19 Vaccines Appear Effective

Two vaccines developed by China’s Sinopharm appeared effective, said a study published in a leading US medical journal.

The inactivated vaccines prevented symptomatic infections by 72.8% and 78.1%, said the study published online in the Journal of the American Medical Association.

A total of 40,832 volunteers from the UAE, Bahrain, Egypt and Jordan took part in the study.

They were equally split into three groups and were given either two doses of the vaccines, three weeks apart, or a placebo.

None of the volunteers, who were given an active vaccine, contracted severe disease, compared with two of those given a placebo, the study showed.​​​​​​​
