看了最近BC的数据,疫苗作用可以忽略不计了

加拿大BC省到目前为止,接种一针的人口 84.2%,两针 76.4%。 疫苗不能阻断病毒传播已经定论了,那么主要关注疫苗的重症保护率。

上面的截图是 B.C. COVID-19 cases and hospitalizations by vaccination status (Aug 10th - Aug 16th, 2021)
New Cases: Unvaccinated: 2620 Partially Vaccinated: 583 Fully Vaccinated: 498
Hospitalizations (重症): Unvaccinated: 95 Partially Vaccinated: 6 Fully Vaccinated: 12
那么,打不打疫苗的重症率如何? Unvaccinated Rate = 95/2620 x 100% = 3.63% Partially Vaccinated Rate = 6/583 x 100% = 1.03% Fully Vaccinated Rate = 12/498 x 100% = 2.41%
换句话说, 不打疫苗如果感染(目前基本都是Delta),重症率3.63%, 打了一针后感染,重症率 1.03% 打了两针后感染,重症率 2.41%

有希望就对了
需要按照打了和没打疫苗的总人口计算 按照感染人数计算会引入额外的selection bias
就感染而言,打了两针的保护率 ((2620/15.8)-(498/76.4))/(2620/15.8)=96.07%
就重症而言,打了两针的保护率 ((95/15.8)-(12/76.4))/(95/15.8)=97.39%

就感染而言,只打了一针的保护率 ((2620/15.8)-(583/7.8))/(2620/15.8)=54.93%
就重症而言,只打了一针的保护率 ((95/15.8)-(6/7.8))/(95/15.8)=87.21%

84.2%的人中才18个住院,15.8%没打疫苗的有95个住院,这怎么忽略不计

楼主变着法子推荐疫苗也算用心良苦,我来凑个热闹发个夏威夷的新闻
JUST IN: Honolulu's mayor announces vaccine segregation system effective September 13. 
If Oahu residents want to participate in society, they will be forced to take an experimental mRNA gene therapy every 5-months into perpetuity. 
This comes after the CDC Director has said that the vaccine does not stop infection or transmission and the CDC's own data shows that the mRNA experiment has killed more people than all other vaccines combined over the last 30-years.
In Hawaii, which has 600-deaths per influenza season, there have been 589-deaths in total from COVID-19 over the last 17-months with 39-deaths under the age of 50 and 0-deaths under the age of 18.
97% of those deaths have had an average of 4-comorbidities according to the CDC.
Governor David Ige announced a "successful vaccination program" on July 30, 2021 after 60% of residents were fully vaccinated.
One month later, the average daily cases are 351% higher than the previous all time high in 2020.

这也太标题党了。数据明明是显示了打疫苗有帮助吗。
