Gates' obsession with vaccines seems to be fueled by a conviction to save the world with technology.

Promising his share of $450 million of $1.2 billion to eradicate Polio, Gates took control of India's National Technical Advisory Group on Immunization (NTAGI) which mandated up to 50 doses (Table 1) of polio vaccines through overlapping immunization programs to children before the age of five. Indian doctors blame the Gates campaign for a devastating non-polio acute flaccid paralysis (NPAFP) epidemic that paralyzed 490,000 children beyond expected rates between 2000 and 2017. In 2017, the Indian government dialed back Gates' vaccine regimen and asked Gates and his vaccine policies to leave India. NPAFP rates dropped precipitously.
