Countries using Chinese vaccines report COVID-19 surge: New York Times report

It added the Seychelles, Chile, Bahrain and Mongolia, which are mostly using Sinopharm and Sinovac Biotech's vaccines and whose 50-68% of the populations are fully vaccinated, were among top 10 countries with worst outbreaks last week.
