SANTIAGO, Chile - A study in Chile, which has one of the furthest-advanced vaccination campaigns in South America -- mainly with China's Coronavac, has found that a first dose alone does not protect against coronavirus infection.

第一针28天内的有效性为3%，基本上可以说是无效，属于误差范围内；第二针打完后2周内有效性28%；第二针二周以后的有效性上升到了56.5%；综合有效率为54%。

It estimated Coronavac's efficacy in real-life conditions at 54 percent -- in line with trial results in Brazil.

The study estimated that for people between 75 and 79 -- targeted in the initial vaccination campaign -- there would have been 80 percent more infections without the vaccine.

这两段是矛盾的。

这个结果基本解释了为什么智利的疫情没有缓解，必须等第二针以后14天才有54%的保护率

 

[向问天]

这个情况我估计，如果打3针，有效率会超过80%。

The study estimated that for people between 75 and 79 -- targeted in the initial vaccination campaign -- there would have been 80 percent more infections without the vaccine.


For those aged 70 to 74, the percentage dropped to 60 percent.

这个不make sense，年纪越大保护力越强？是不是样本太少？

应该是因为年轻的更可能在注射后参加社会活动。

 

[向问天]

应该每两个星期接种一次，一个月内接种3次，效果会大幅提高。

解释比较牵强，实验数据对比的是同年龄打疫苗和不打疫苗的人的感染率。

现在就只有结果出来，没有数据佐证。make不make sense就只能这样了

说不定这个疫苗对老年人的保护率高呢

等等看智利有没有biotech效果公布，两个数据在一个地方同一个时间真刀实枪比较。当然有可能有一定差别，比喻有钱人或者权贵打biotech疫苗

老向，恕我直言，这特么还不如阿三的阿斯利康的！

起码一针不行，但是两针不一定，智利一半都是巴西变异病毒。
