So I am writing this on 16 November, the day that Moderna announced that their vaccine has a 94.5% effectiveness rate. At this point, I’m thinking that they are just trying to outdo Pfizer’s vaccine. Although it is part and parcel of competition, these are potential vaccines that will be injected into people, I hope people will not get too amazed by the small sample size. I trust that the vaccines works Although the vaccine reports such a high effectiveness rate, there are still many skeptics. For example, the data and test subjects are not peer-reviewed. They are just bold claims from the company. But I would like to give the companies the benefit of the doubt. The vaccines probably work. However, I believe that the vaccines do not actually have such a high actually effective rate because the sample size is so small. (Less than 100 for each company) Even then, an effectiveness rate of more than 50% would be good enough....
