BEIJING: Antibodies triggered by two Chinese COVID-19 vaccines are less effective against the delta variant than other strains, but the shots still provide protection, a Chinese disease control researcher told state media.
The delta variant of the new coronavirus, which was first detected in India, is becoming the dominant form of the disease globally with its increased transmission potential. World Health OrganizationThe Chief Scientist warned last week.
in an interview broadcast by China Central Television late Thursday night, fang Zijian, researcher and former deputy director, Chinese Center for Disease Control and Prevention, did not provide further details.
Without naming the two vaccines, Fang said they fall under the category of inactivated vaccines, which contain “killed” coronaviruses that cannot replicate in human cells.
Five of the seven domestically developed vaccines in China’s mass vaccination plan are inactivated vaccines. Shots of these include Sinovac Biotech and sinoform Used in countries such as Brazil, Bahrain and Chile.
Officials said the delta variant has caused infections in three cities in southern Guangdong province, where a total of 170 locally confirmed patients were reported between May 21 and June 21.

About 85% of Guangdong’s cases in the latest outbreak were found in the provincial capital, Guangzhou.
