I'm pretty sure that life expectancy had a huge effect on the world population. In 1950, the world population was under 3 billion. Before 1950 the average life expectancy in the world was never over 50. In 1900, it was only 31! This is thanks to modern medicine and the development of vaccines. That is why our population has grown so quickly over the past century. You also have to keep in mind that infant mortality has gone way down.

Note when, in the decline of all of these diseases, vaccination was actually put into play. That's pretty strong proof of their actual impact and effectiveness.

I don't believe they are, but they are certainly not the miracle they are marketed to be by the medical/industrial complex.
