(2009, 2010, 2011, 2012, 2014, 2016 and 2017), most often in reference to the Gates Foundation's outsized financial and ideological support for global vaccine programs. As Gates says, "In the same way that during my Microsoft career I talked about the magic of software, I now spend my time talking about the magic of vaccines."

Gates's words give us an immediate clue that he is engaging in his own brand of magical thinking—which social scientists define as "illogical causal reasoning." How else to explain his simplistic endorsement of vaccines as a miraculous intervention with unmitigated benefits and no down side? The Gates Foundation's global spreadsheet appears to have no room to tally the massive flood of vaccine injuries afflicting children worldwide, despite abundant evidence that this damage is standing the vaccine risk-benefit calculus on its head and turning childhood into an extended round of Russian roulette.

In a widely cited 2014 blog post on the "miracle of vaccines," Gates expressed enthusiasm about the "inspiring" data on vaccines and the "fantastic" and "phenomenal" progress being made to expand vaccine coverage. There is one major problem with Gates' professed reliance on "data," which is that the philanthropist ignores fundamental historical facts governing infectious disease and vaccine timelines.
