It’s a question Many parents are concerned about giving their children too many vaccines in a short period of time, Over the past decade, American parents have become increasingly anxious about following their pediatrician’s recommendations to fully vaccinate their children. As a result, about 40 percent of American parents today have chosen to delay certain vaccines or outright refuse to allow their children’s physicians to vaccinate their children with one or more of the recommended or mandated vaccines. Their anxieties arise from several sources, but the most widely discussed concern among parents is the claim that vaccines may cause autism. Despite assurances from every mainstream scientific and medical in situation that vaccines do not cause autism, millions of parents fear that they do, and it shapes their decisions about whether and when to vaccinate their children. The modern American debate over vaccines and autism is a proxy debate. It is a debate in which both sides uphold claims that are simplistic stand ins for real problems. ( …show more content…
The immune response elicited by this primary exposure to vaccine pathogen creates immunological memory, which involves the generation of a pool of immune cells that will recognize the pathogen and mount a more robust or secondary response upon subsequent exposure to the virus or bacterium. In successful immunization, the secondary immune response is sufficient to prevent disease in the infected individual, as well as prevent the transmission of the pathogen to others. For communicable diseases, immunizations protect not only the individual who receives the immunization, but also others with whom he or she has contact. High levels of vaccination in a community increase the number of people who are less susceptible or resistant to illness and propagation of the infectious agent. Unvaccinated individuals or those who have not developed immunity to this pathogen are afforded an indirect measure of protection because those with immunity reduce the spread of the pathogen throughout the entire population. The larger the proportion of people with immunity, the greater the protection of those without immunity. This effect is called “herd immunity.” Herd immunity is an important phenomenon as immunization programs rarely achieve 100 percent immunization in a population; and in some cases, previously vaccinated persons
