Five out of the seven domestically developed vaccines in China’s mass inoculation scheme are inactivated vaccines. These include shots from Sinovac Biotech and Sinopharm used in countries such as Brazil, Bahrain and Chile.

Now, researchers at Washington University School of Medicine in St. Louis have found that a single mutation gives SARS-CoV-2 the ability to enter cells through another route – one that does not require ACE2. The ability to use an alternative entry pathway opens up the possibility of evading COVID-19 antibodies or vaccines, but the researchers did not find evidence of such evasion. However, the discovery does show that the virus can change in unexpected ways and find new ways to cause infection. The study is published in the journal Cell Reports.
