Let me at the outset tell you that all these success rates are based on very small samples of persons tested. You will get a true picture only when you consider a much larger sample and test it more elaborately. So, these results are good but you will have to wait.

Let me now talk about the progress on the vaccine. Even as the vaccine by Pfizer and Biontech has already claimed 90% effectiveness based on interim data, Moderna of Germany has claimed that its vaccine candidate delivers 95% effectiveness.

Clearly, this gives an edge to the Moderna vaccine and makes the vaccine more preferred among the buyers. There is another advantage for Moderna. Pfizer vaccine needs to be stored at -74 degrees Celsius temperatures and that is something not normally available for commercial use.

ON the other hand, Moderna vaccine can be stored at more normal cooling temperatures making it more viable and feasible from an execution point of view. Of course, the race for the vaccine has just begun and could have more twists and turns later. There are at least 16-20 vaccine candidates at advanced stages of testing.
