Even in the current age of high-tech medicine, there is an ever-growing population of those vocally opposed to the modern practice of routine childhood vaccinations. Many believe that vaccines are unsafe because they are not natural, or that they cause autism, and feel that the risk of negative side effects is not worth the benefit of protection against the infectious diseases themselves. Others simply don't want to be told what they can and can't do for their children's health. While the concerns may be well-intentioned, the reality is that the advent of vaccines has significantly changed the disease landscape in the United States for the better. The growing reluctance and refusal of some parents to immunize their children has led to an increase in the incidence of measles and other serious and often fatal diseases around the world. Scientists use recombinant DNA and monoclonal antibodies, and even the targets themselves are constantly changing as some scientists study diseases. which are not infectious like allergies and even addiction (The College of Physicians of Philadelphia). With serious diseases all but eradicated, the public neither feels nor remembers the consequences of these infections, and is therefore unaware of how deadly and terrible they can be. No one really remembers the scary sound of a baby with whooping cough or the stories of birth defects due to exposure to rubella. Pictures of children with braces due to polio are simply black and white photos found in old textbooks and scrapbooks. People confined to an “iron lung” and coughing blood into a handkerchief are only seen in old TV Westerns. This means that parents are less obliged to pay attention to their children's vaccination or even their own vaccination, as recommended by the health community. The out of sight, the out of mind
