"The first wave in 1918 was relatively mild, many experts speculate, because the virus had not fully adapted to humans. And as it did adapt, it also became more lethal. However, there is very good evidence that people who were exposed during the first wave developed immunity — much as people get protection from a modern vaccine. A similar kind of immune-building process is the most likely explanation for why, in 1918, only 2 percent of those who contracted the flu died. Having been exposed to other influenza viruses, most people had built up some protection. People in isolated regions, including American Indian reservations and Alaskan Inuit villages, had much higher case mortality — presumably because they had less exposure to influenza viruses."
Where Will the Swine Flu Go Next?
So why are we so obsessive and coercive in giving children flu shots? Wouldn’t getting an actual mild flu be better immunilogical protection than the pseduo-infection of a flu shot?
