While millions of Americans receive vaccinations each year, a vocal segment of the population is opposed to all immunizations--some even refusing to get mandated vaccinations for their children. In "The Vaccine Controversy," Dr. Kurt Link--a specialist in internal medicine--explores that paradox and provides a history of vaccine development, including such possible future vaccines as those being developed in the hope of immunizing against HIV. A strong supporter of vaccination programs, Link explains the immune system and how it works, as well as outlining the various types of vaccines (including the efficacy and potential toxicity of each). Appendices spell out current medical recommendations for vaccines, describe the legal issues involved in decisions to vaccinate or not, and explain the workings of clinical trials where work is done to determine if a vaccine is effective or not, or has any remarkable side effects.
