(1) Geoffrey Garnett in a research project called “Role of Herd Immunity in Determining the Effect of Vaccines against Sexually Transmitted Disease” (2005) claimed that vaccination protects the immunized as well as the population that cannot receive immunizations. (2) An algorithm was developed that modeled STI rates based on data obtained from childhood vaccinations. (3) The purpose of this study was to show that if everyone that can safely receive a vaccination actually got vaccinated, STI rates will decrease. Those who cannot receive a vaccination will be protected via “herd immunity,” the notion that if majority of the population is vaccinated, they will protect the individuals who are not. (4). Garnett uses a professional tone and terminology to communicate findings to other researchers, scientists and doctors interested in HPV vaccination and herd immunity.
