Eight per cent of unvaccinated Covid-19 patients here in the past seven weeks had their condition worsen to the point of requiring supplemental oxygen, said Health Minister Ong Ye Kung on Monday (May 31).
In contrast, during the same time period, only one out of 93 - slightly over one per cent - of those who were vaccinated faced a similar situation, said Mr Ong, who co-chairs the multi-ministry task force (MTF) tackling the coronavirus outbreak here.
Acknowledging that these statistics, which reference locally transmitted cases, did not constitute "a full-scale empirical study", Mr Ong said that as more data becomes available, the protective benefits that Covid-19 vaccination will give an individual will become clearer.
