Full Vaccination的定義也許會被修改為成打了三針。
提前說明一下： 科學家需要時間觀察，收集數據和分析，請不要抱怨這個太晚了，或者改來改去的。
1. 加強針有助於防止傳染：
here were 149 cases per 100,000 people on average each week. For those who had only two doses, it was 255 cases per 100,000 people.‘
2.加強針有助於防止得病
A third study, published in the medical journal JAMA, showed that having a booster helped prevent people from becoming ill with Omicron. That study of just over 13,000 US Omicron cases found that the odds of developing a symptomatic infection were 66% lower for people who were boosted compared to those who had only received two shots.
3. 加強針對住院的防止又90%的有效率
Getting boosted was 90% effective at preventing hospitalizations during a period in December and January when Omicron was the dominant variant, according to a CDC study that looked at nearly 88,000 hospitalizations across 10 states.
In comparison, getting two shots was 57% effective when it had been at least six months past the second shot
