DUBAI, United Arab Emirates – Human trials of a Chinese vaccine in the United Arab Emirates have produced positive results, the UAE national health authorities said on Wednesday, citing an effectiveness rate of 86%.
The number was released by the United Arab Emirates’ Ministry of Health through the state news agency WAM and includes an “interim analysis” conducted by Sinopharm’s China National Biotec Group (CNBG). The 10 million-inhabitant Gulf state began Phase 3 human trials of the experimental vaccine in July and approved emergency use for health workers in September.
“The registration of this vaccine is a decision in response to the application by Sinopharm CNBG. The announcement is a significant vote of confidence by the UAE health authorities in the safety and effectiveness of this vaccine,” the Ministry of Health said Wednesday. The vaccine itself was developed by the CNBG’s Beijing Institute of Biological Product.
The Phase 3 studies included 31,000 volunteers from 125 nationalities, with the ministry highlighting the UAE’s diverse and large expatriate population – which makes up approximately 90% of the country’s total population – as an advantage in conducting human testing.
However, the announcement contained few details. The parameters of the studies, how many patients received the vaccine dose compared to placebo, were not elucidated, and no side effects that occurred in patients were mentioned.
After stating 86% effectiveness, the ministry said, “The analysis also shows the vaccine has a seroconversion rate of 99 percent of the neutralizing antibody and 100 percent effectiveness in preventing moderate and severe cases of the disease.” Seroconversion is the process by which an antibody is identified in a patient’s blood.
It added that “the analysis shows no serious safety concerns.”
It is unclear how the 86% potency figure was calculated. CNBC asked Sinopharm for a comment.
