In this special edition of the Perpetual Notion Machine, we discuss a timely topic for this winter – vaccinations and the personal and civic responsibility of everyone to get vaccinations to prevent the spread of highly contagious diseases like measles, whooping cough, and the flu. Our guest is John Tempte from the UW-Madison Department of Family Medicine, who talked with PNM’s Bill Scanlon. John is also Chair of the CDC Advisory Committee on Immunization Practices and Chair of the Wisconsin Council for Immunization Practices. John was one of many who were surprised about the sudden rise of measles outbreaks when the medical community thought that measles was eliminated in the U.S. He also explained that there is no evidence that measles vaccinations cause autism, but did go into the possible risk of the vaccinations. And John discussed with Bill the need to get flu vaccines that helps fight a disease that not only effects kids, but also older, senior citizens.
