Not everyone in Europe got the black plague. Some villages didn't get it at all while others were wiped out. Oftentimes rich people got it worse than poor villagers, a probable cause is that many poor people couldn't afford the rich and unhealthy diets of the wealthy. Of course many poor villages were decimated, a major factor probably being poor hygeine, overcrowding and poor sanitation. So, have you gotten your shot? By the way, you still haven't submited your double-blind peer reviewed scientific study on the effectiveness of the HPV vaccine. How am I supposed to make a decision to inject myself with a product without this data?
