I think there's not enough information there to make conclusions about the vaccines. There's roughly a million vaccinated people in Singapore, a small number of people that are vaccinated and still get sick is expected even with very efficacious vaccines.
Don’t get me wrong. The vaccines are great at preventing severe disease. But they won’t prevent an outbreak of 20-30% of your population is unvaccinated.
Data seem to point at keeping some level of restrictions until everyone who is vulnerable has an opportunity to get the vaccine. Otherwise you’ll be dealing with outbreaks - smaller in scale, but outbreaks none the less.
