The United Arab Emirates (UAE) said Wednesday a Chinese coronavirus vaccine tested in the federation of sheikhdoms is 86% effective, AP news reported. According to AP, this was revealed in a statement that provided few details but marked the first public release of information on the efficacy of the shot. The announcement brought yet another shot into the worldwide race for a vaccine to end the pandemic, a scientific effort that has seen China and Russia compete with Western firms for an effective inoculation. While questions remain about the Sinopharm shot, already at least one country outside China plans to roll it out in a mass-vaccination campaign. The UAE, home to Dubai and Abu Dhabi, conducted a trial beginning in September of the vaccine by Chinese state-owned pharmaceutical giant Sinopharm involving 31,000 volunteers from 125 nations. Volunteers between 18 and 60 years old received two doses of the vaccine over 28 days. The UAE’s Health and Prevention Ministry announced the results via a statement on the state-run WAM news agency, saying they “have reviewed Sinopharm CNBG’s interim analysis of the Phase III trials.”
