This was titled as a 5 part series, but only 1 and 2 were ever posted on this linked site from what I can find. However, the articles were taken from a site called www.firstfreedoms.org, though all parts of the article on there no longer exist and were taken down at some point. I checked archive.org and found part 3 had been archived, but parts 4 and 5 were not. >Part 1 was posted November 13, 2018 >**Did a Military Experimental Vaccine in 1918 Kill 50-100 Million People Blamed as "Spanish Flu"?
