They needed to. This is why some people have been dying. Should have got boosters going more aggressively when calls for that started during delta. The most vulnerable got AZ which ran out of protection v quickly. Knew that ages ago for delta. Omicron even more so.
The changes to 3rd dose interval in NSW, VIC and SA mean an additional ~3.8 million people have become eligible for their booster.
This now means more than half of the total population have either had their 3rd dose or are eligible.
