A whole lot of people study vaccination, and have been for 109 years. Everything is up for dispute from specifics to generalities, from medical studies to policy ones. Yours is a minority position. But, it has advocates. They just haven't convinced the majority.

The Gates Foundation is trying to influence indian policy and practice, and other places. This is based on the idea that immunization (also diet, sanitation, and deworming) significantly lowers childhood mortality, especially in areas of high prevalence.

You're implying this is all a big mistake (or conspiracy). Immunization is dangerous, and hurts more than it helps. I don't know of any convincing studies that have reached this conclusion. Certainly not the the policy level. The closest I've seen to a reliable refutation is at the individual level, in low prevelance places.

Do you want the 99.99% effective vaccine or the far lower chance of not getting a deadly desease?

In the areas where herd immunity is a thing because everyone is vaccinated you might be fine, but if that's not the case.. just look at the way Polio devastated lives before the vaccination.
