As a biochemistry professional, I have followed the science of COVID-19 before most people had heard about it, before it was reported outside of China. Along the way from the pandemic start, through vaccine development, the overwhelming of hospitals, and the arrival of the first COVID-19 vaccines, I have read and listened to politicians and some scientists argue that natural immunity would be good enough. The idea is that you should just let the disease spread and natural immunity will build up. Well, yes that is true, if you survive a viral infection you will most likely have some immunity for some time. The problem with their suggestion however is the survival part and the cost of herd natural immunity. That cost is permanent damage and increased personal risk of future death from MACE. Fortunately, the first Trump administration decided to go with the strategy of "Warp Speed" to get vaccines developed faster than at any time in history. Read on for some explanation.
