Here is an October 15, 2020 presentation outlining the Moderna vaccine development. Obviously we know more details at this point, but an interesting comparison in this early data is the vaccine's effectiveness compared to natural immunity developed during infection.

Another point to note is how quickly a vaccine candidate was developed after the DNA sequence was available. Compare this to the historic development schedule. Now, we have much better tools at our disposal and should be careful when comparing "traditional" (old) methods with current technology.
