Singapore currently has the same problem, with higher vaccination (90% adult) but even even lower natural immunity (Less than 5%).
They have to open up in the next 6 months because their economy is being destroyed (International airport that was top 5 in world in 2019, now 8% of 2019), but when they open it will be OBVIOUS to everyone that even over 90% vaccination doesn’t stop the expoDential spread.
thanks
