How a totalitarian dictatorship like China sets Covid-19 vaccination priorities

And we still do not know what exactly happened in Wuhan or elsewhere in China where the SARS-CoV-2 virus first originated

"Mass testing and lockdowns are familiar parts of China’s Covid-19 strategy, but vaccinating the elderly isn’t. While about 88% of Chinese residents had received two vaccine doses as of mid-March, among those over 80—those most at risk of severe illness and death from an infection—it was just 51%. When vaccines rolled out, China’s priority was getting them to people of working age to rev the economy. Reluctance among family members and officials to expose the elderly to potential side effects was one factor behind the low vax rate among older people. A lack of a sense of urgency was another."

And lately, particularly the elderly in mega cities like Shanghai suffer under the new wave of strict lockdowns. 

Contrast this with Western countries, where the elderly had a choice and were provided with vaccine doses. In many Western countries the vaccination rates among the elder are way above herd immunity (about 67%, and sometimes over 80-85%).
