@yogthos Booster plays an important role in protecting seniors from omicron. The rate of 90% is for basic vaccination without taking booster into consideration and throughout ages. Though, As of Nov. 28, 2022, days before the reopening, only 65.8% of the people over 80 years old have gotten at least basic vaccination of 2 dose and 40.38% booster. And people did notice in daily talk online and offline an increase in death around them and an impact on hospitals, but because conclusive and quantitative reports are suppressed, no one can really tell the effect.
