Whether it is a young adult, middle-aged adult, or a senior citizen, everyone needs vaccines to help keep them healthy. The viruses and bacteria that cause many diseases are still a threat today(). Many people believe that since they have received a vaccine in their childhood they don 't need a vaccine as they get older, but the fact is that The protection a person may get from childhood vaccines can decrease over time (Stern, Markel). Unvaccinated adults may not realize that not only are they at risk themselves, but they also pose a risk of passing diseases on to the young, the frail and the elderly (FDA). For example, adults are the most common source of whooping-cough infection in infants, who are at high risk of serious complications and death. Some people believe there is no risk involved when they decide to skip vaccination due to the fact that diseases such as polio, measles and tetanus are now rarely seen in the U.S, but that is not true an unvaccinated person is always at risk for any kind of disease. Others do not believe that certain vaccine-preventable diseases, such as chickenpox and measles, are particularly serious (Daley,Glanz). Some people think they are too old to receive a vaccination or contract an illness, but in an article published on a website Kaiser Health News it states “Vaccines are important at all ages” (Gorman). People virtually never see those diseases in the United States anymore, but they …show more content…
The key to this achievement is mandatory vaccination of the public. An article published on a website titled Vaccine Information states “Outbreaks of preventable diseases occur when many parents decide not to vaccinate their children”. Statistics show that the failure to vaccinate children endangers both the health of children themselves as well as others (Daley and Glanz). Vaccines can prevent outbreaks of contagious diseases only when everyone in the community is immunized. Through community immunity, This means that a sufficient portion of the population must be vaccinated to an infectious disease so that the disease is completely eliminated and less likely to spread from one person to another. “The success of an immunization depends on high rates of acceptance and coverage” ().As the number of vaccinated people increases, the protective effect vaccines increase as well. While the herd immunity threshold may start with 40% of the population vaccinated for some diseases, most diseases require vaccination rates as high as 80% – 95% to prevent outbreaks. Moreover, herd immunity protects those who cannot be vaccinated or for whom the vaccination was not successful, such as people with weak immune systems, chronic illnesses or
