有趣的是，有一群志愿者先接种半剂疫苗后，再接受完整的一剂疫苗，防护效力就增至9

Covid-19: Oxford University vaccine shows 70% protection(2020-11-23)
https://www.bbc.com/news/health-55040635
There were 30 cases of Covid in people who had two doses of the vaccine and
101 cases in people who received a dummy injection.
The researchers said it works out at 70% protection.
When volunteers were given two "high" doses the protection was 62%, but this
rose to 90% when people were given a "low" dose followed by a high one. It's
not clear why there is a difference.
Why is the low dose better?
There is not a straightforward answer.
One idea is the immune system rejects the vaccine, which is built around a
common cold virus, if it is given in too big an initial dose.
Or a low then high shot may be a better mimic of a coronavirus infection and
lead to a better immune response.

牛津疫苗保护力7成不够强? 专家剖析先天劣势和优势(2020-11-23)

牛津疫苗疫苗整体是70%
然后有两种接种方式,先打1剂,隔一个月再打1剂,防护是62%
另一种是先打半剂,隔一个月再打1剂,防护90%
mesenchymal大有推文分享意见
推 mesenchymal: 两种剂量的人数也有明显落差 1/2> 1 67.87.235.133 11/23 20:31
→ mesenchymal: (2741人 90%) 1>1 (8895人 62%)所以 67.87.235.133 11/23 20:31
→ mesenchymal: 我觉得目前资料不足下难以直接比较， 67.87.235.133 11/23 20:31
→ mesenchymal: 保险来看还是用整体评估70% 效率。 67.87.235.133 11/23 20:31
牛津疫苗相关的数据就如上,可能 Lancet 的paper里面有你提供的数据
但我是看不懂所以我没看,相关报导牛津疫苗没有95%这个数值
