Also the HIV epidemic is thought to have been started by government vaccination programs: https://en.wikipedia.org/wiki/History_of_HIV/AIDS https://en.wikipedia.org/wiki/History_of_HIV/AIDS But a lot of 'pro-vaccine' folks just completely ignore the black swan problem, which is wrong. Also the flu vaccine lowers your chances of dying in any given winter, but many studies show that it increase your chances of the flu dying over the course of your life. This is because the flu vaccine only confers immunity against those strains for 6 - 18 months, whereas getting the flu confers immunity against those strains for decades: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2870374/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2870374/ http://www.cidrap.umn.edu/news-perspective/2014/11/study-adds-more-data-effects-consecutive-year-flu-shots http://www.cidrap.umn.edu/news-perspective/2014/11/study-add... Also a lot of vaccines have had very little human testing. E.g. if you look at the CDC webpage for the japanese encephalitis vaccine, it says "There are no efficacy data for Ixiaro. The vaccine was licensed in the United States on the basis of its ability to induce JE virus neutralizing antibodies as a surrogate for protection." http://wwwnc.cdc.gov/travel/yellowbook/2016/infectious-diseases-related-to-travel/japanese-encephalitis http://wwwnc.cdc.gov/travel/yellowbook/2016/infectious-disea... I think there is a major lack of critical thinking of both sides of the issue.
