防感染的数据我不知道,但防hospitalization应该是真实的。看这个新闻 https://abc7ny.com/covid-in-kids-vaccine-omicron-variant-children-with/11393287/ 里面提到,Of the 5- to 11-year-old children admitted to New York City hospitals with COVID from the week of December 5 until the current week, none were fully vaccinated.
啥都不信难道你自己采集数据做统计分析?
