Moderna vaccines the best — and Sinovac least effective — at stopping covid deaths, Singapore data suggests

In a real-world indicator of how coronavirus vaccines are performing, Singapore has released new figures suggesting shots produced by Moderna and Pfizer-BioNTech are much more effective at preventing deaths than the Chinese-developed Sinopharm and Sinovac doses.

Eight hundred and two people died of covid-19 in the city-state in 2021, of whom 555 were not fully vaccinated, while 247 received one of several locally available vaccines, Health Minister Ong Ye Kung told lawmakers on Monday.
