Vaccines are back in the news, after an outspoken anti-vaccine advocate changed her stance on the topic. Last year, Forbes published an infographic created by Leon Farrant, a graphic designer in Purchase, NY, which visualizes the dramatic affect vaccines have had on reducing the number of cases for some of the world’s most deadly diseases. The data is based on data published by the Centers for Disease Control & Prevention, but we think Farrant does a much nicer job displaying the information. In almost all cases, except pneumococcal diseaase, there has been at least a 75% reduction in the number of cases, and vaccines have effectively eliminated diphtheria, polio, and small pox.
