The government may be ready to accept the coronavirus vaccine of China’s Sinovac Biotech even if it has shown 50-percent effectiveness, or lower than the 95-percent effectiveness of US vaccines from Pfizer and Moderna, and 70 percent of AstraZeneca.

“The 50-percent efficacy is acceptable because that is the minimum requirement set by the World Health Organization for a vaccine to be used by a country,” Jaime Montoya, executive director of the Philippine Council for Health Research and Development under the Department of Science and Technology.

“We have to also bear in mind that a vaccine efficacy may actually change – it may go up or it may go down as more and more people are using it when they are actually rolled out,” he added.

He explained that the 50-percent rate of Sinovac’s vaccine is its “overall efficacy” and could be higher “if we actually break them down into groups.”

Also, Brazilian researchers have reportedly said that Sinovac’s vaccine is more than 50-percent effective based on trial data. Brazil was one of the countries where the Sinovac vaccine was tested. SOVEREIGNPH
