CDC’s 1963 mortality and morbidity data show that prior to the introduction of the measles vaccine, improvements in nutrition and hygeine had already driven US measles mortality in U.S. to 400 per year, a population ratio of 1/500,000 and a death-case ratio of 1 in 10,000，about the same risk of dying from a lightning strike。 Most of those mortalities were among malnourished children, many of whom suffered from intellectual disabilities. The best evidence suggests that measles mortalities would have continued to drop with the introduction of food stamps, W.I.C, and otherchildhood nutritional programs passed during the War on Poverty after1964 to relieve hunger in impoverished communities.
[a study published in PNAS] found that influenza vaccination actually increased transmission of the virus, with vaccinated individuals shedding more than six times as much aerosolized virus in their breath than unvaccinated individuals.
