I will look at that link later to refresh my memory, but I don’t trust anything that the CDC has to say on the subject, and I don’t trust studies that were conducted by the makers of things, nor studies that are conducted by organizations that have ties to the makers of stuff.
I have spent a great deal of time researching and looking at data. That has made me skeptical. Truth rarely comes out with respect to such things until 50 years down the road.
The CDC has saved a lot of lives in Africa from ebola.
