People who received Sinovac shots are excluded from Singapore’s count of total vaccinations against COVID-19, officials in the city state said, citing inadequate efficacy data for the Chinese-made vaccine, especially against the contagious Delta variant.
The Delta variant has become the most prevalent strain of COVID-19 in Singapore since a cluster of infections was identified at the airport in May. The government subsequently moved back to stricter curbs on social gatherings and public activities, though it has begun relaxing some of those restrictions.
Only people who participated in the national immunization programme, which currently uses the Moderna and Pfizer shots, are counted in the tally for vaccinations.
Over 3.7 million people have received at least one dose of the Pfizer or Moderna vaccines, covering about 65% of the population, and nearly 2.2 million have completed the two-dose regimen.
