If you look at past graphs, the US could have been fully vaccinated by mid-June or perhaps July. The current problems faced by the hospital system in some areas of the US were probably avoidable, so what is true for Singapore’s policies is not the same in the US. But it is likely quite hard to predict hospital utilization, since it changes many weeks after we needed to change behaviors to maybe avoid it.
