Book excerpt: The controversy surrounding the measles, mumps and rubella (MMR) vaccine and autism has raised unprecedented questions about the communication of health and science. Health, Risk and News: The MMR Vaccine and the Media examines how this story came to be so influential and asks if the media are to blame for unduly panicking the public. Drawing on comprehensive research - on media coverage, interviews with a range of journalists and sources, and analysis of audience opinion - this book explores how medical controversies are covered, with attention to issues of balance and objectivity, expertise, news values, risk and media effects. It will be of interest to students and scholars of media studies, journalists and health professionals.
