Yоu heаr sоmeоne tаlking on а news program. They are discussing vaccination and they claim, “If you are concerned about a disease, get vaccinated for that disease, then you don’t need to worry about those who do not vaccinate. You and your family will be protected.” You know that the equation for the critical immunization threshold for a disease is 1-1/R0 and that the R0 for measles is about 15. Explain, using what you know about the critical immunization threshold and vaccines, why the TV commentator’s stance is overly simplistic. As one part of your explanation, state what percentage unvaccinated people might make measles a larger public health problem. This question can be answered in 4-5 sentences.
