我不知道你Astrazeneca(牛津)的數據在哪看到的,我是沒看過牛津疫苗出現過95%的數字

研究人員表示,99%的受試者在施打疫苗後成功出現抗體,而老年人身上出現「強烈免疫

有趣的是,有一群志願者先接種半劑疫苗後,再接受完整的一劑疫苗,防護效力就增至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.

牛津疫苗保護力7成不夠強? 專家剖析先天劣勢和優勢(2020-11-23)

牛津疫苗疫苗整體是70%
然後有兩種接種方式,先打1劑,隔一個月再打1劑,防護是62%
另一種是先打半劑,隔一個月再打1劑,防護90%
mesenchymal大有推文分享意見
推 mesenchymal: 兩種劑量的人數也有明顯落差 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: 我覺得目前資料不足下難以直接比較, 67.87.235.133 11/23 20:31
→ mesenchymal: 保險來看還是用整體評估70% 效率。 67.87.235.133 11/23 20:31
牛津疫苗相關的數據就如上,可能 Lancet 的paper裡面有你提供的數據
但我是看不懂所以我沒看,相關報導牛津疫苗沒有95%這個數值
