Vaccination Research Paper

Herd immunity exists when the maximum amount of people are vaccinated, reducing the risk of infection for people at serious risk (i.e. immunocompromised adults, chemotherapy patients, or newborns). When fewer people are unvaccinated, a disease has fewer hosts to spread to. At this point, most states allow vaccination exemption for religious or “moral” conflicts in addition to medical reasons. People who exempt vaccines

Vaccines are one of most successful and cost effective public health preventive tool in current century for preventing communicable diseases. According to UK Health Protection Agency (HPA), vaccination is the second most effective public health intervention worldwide. Immunization protects the individual as well the community from serious diseases. Since the implementation of immunization there has been a 95% reduction in the cases 4. According to WHO immunization prevented 2million deaths worldwide.

Vaccinations play a very large part in the prevention of diseases spreading. When enough people, 95% according to the CDC, have been vaccinated, the other 5% not vaccinated are protected through herd immunity (Kluger). This term is often used in discussion with

Herd immunity is essential in a community where people are unable to be vaccinated. The greater the quantity of people that are immune to a disease, the lower the chance of someone who is vulnerable contracting said disease. Whooping cough is an excellent example of a vaccine that strongly relies on herd immunity. With whooping cough, babies are particularly at risk of infection, therefore it is essential that immediate family members such as the; mother, father and grandparents are all immunised before coming into contact with the

Those who cannot be vaccinated or for whom vaccines are not effective rely on the concept of “herd immunity” to protect themselves; it is a social responsibility to get vaccinated in order to protect the rest of the population. There are many people in Canada who are completely unable to be vaccinated– people without a fully-functioning immune system, people undergoing chemotherapy treatment, people with HIV, newborn babies, and the elderly. However, when a certain portion of a community is immunized against a contagious disease, the other members of the community are protected against that disease because of “herd immunity”– if 95% of the population is vaccinated, the disease cannot spread

Eighty to ninety percent of the population needs to be vaccinated to prevent the potential spread of a disease (percent depends on the infectiousness of the disease). Another valid reason to vaccinate oneself is to create a secure blanket of immune people to protect the unfortunate individuals without the choice of becoming vaccinated. The strategy of protecting others who have not received vaccinations is called herd immunity, which is a more essential reason to become vaccinated compared to only protecting oneself. Those who cannot receive vaccinations are people that have severe allergic reactions to the preservatives in vaccines and younger children. In a Ted Talk, Romina Libster explains the importance of herd immunity, “People who are

Vaccinations demonstrate the benefits of preventing suffering and death from infectious diseases. According to the Centers for Disease Control and Prevention (CDC), Vaccinations were approved as a number one on the list of the Ten Great Public Health Achievements for the United States from 1900 to 1999. If a critical number of people within a community are vaccinated against a particular illness, the entire group becomes less likely to get the disease. This protection is called community, or herd, immunity. On the other hand, if too many people in a community do not get vaccinations, diseases can reappear. Herd immunity has played major role in reducing continual endemic transmission of a number of disease, as a result, benefiting the

Herd immunity protects people from meeting another person who has a disease by reducing the cases of disease. Herd immunity is only possible by vaccinating a large number of people. For highly infectious diseases like the measles, 95% of the community must be vaccinated for herd immunity to be succesful.2 With today's transportation system, the likelyhood of a person who is presymptomatic getting on a plane and traveling to another country is a real possibility. Without herd immunity this person could infect dozens of people without knowing they are ill.

When children who have been vaccinated do contract a disease, despite being vaccinated against it, they usually have milder symptoms with less serious complications than an un-vaccinated child that gets the same disease. It is true that some children who receive vaccinations may still become ill when exposed to other disease-ridden children. Research shows that 70-90% of the entire population must be vaccinated to attain “herd immunity”, “the resistance of a group to attack by a disease to which a large proportion of the members are immune.” (Farlex, 2012) When herd immunity is accomplished the spread of the disease can be averted throughout. If all parents were to take proper responsibilities and keep their children’s immunizations up-to-date, herd immunity would be achieved against all 16 of the major life threatening diseases.

Vaccines not only protect those who can immunise, but they also protect those who are not old enough or can’t vaccinate due to medical reasons. “Herd immunity is a form of immunity that occurs when the vaccination of a significant portion

Herd immunity’ refers to the resistance of a group attacked by a disease because of the immunity of a large proportion of the members and the consequent lessening of the likelihood of an infected individual coming into contact with a susceptible individual 9. Herd immunity is achieved by mass immunization against communicable diseases 10. However, not all vaccines are equally effective in providing herd immunity. For instance, though mumps vaccine has been available for several decades, mumps continues to be highly prevalent in several regions of the world, likely due to waning immunity over time and inadequate immunization coverage.

Since the beginning of time, people have been fighting many different kinds of diseases and viruses. Vaccines were created in the early 1800s to prevent these diseases and viruses. As a result of vaccines, twelve deadly diseases have been averted and the world no longer has to worry about the smallpox virus. Vaccines protect us before we can even get sick. A vaccine pre-arms the immune system by sending in weakened or dead version of a germ, just enough to be recognized by the white blood cells. When detected, your immune system responds by making proteins called antibodies. The antibodies execute the vaccine germs just as they would exterminate disease germs. Then your memory cells remember the germ so they are prepared next time. This is like a drill for your immune system so when you are exposed to a real disease, your antibodies will be primed. Though vaccinations benefit you in many ways, a lot of people question its effectiveness and safety.

Vaccines are considered as something that has saved many lives. When children are injected with vaccines, they have a lower chance of getting dangerously sick and not being able to fight off the infection. Theories exist that vaccines can cause more problems, like autism and worsened sickness, however, scientists have concluded that this is a rare occurrence. Schools require vaccines to keep all kids healthy, and the ones without vaccines are often the initiators of an outbreak of sickness in a school. Vaccines work by adding a small dose of the sickness, such as chicken pox, to help the body learn how to fight off and prevent the sickness without the child getting sick from it. Bodies with vaccines then create antibodies, or a kind of antidote

In contrast, a positive aspect of many people having vaccinations is herd immunity. Herd immunity is the occurrence where a large proportion of a specific population is vaccinated to provide them immunity, and as a result, it also gives some protection to the people of the population who have and yet developed immunity. This happens as the a large group of vaccinated individuals are protected from a virus and creates difficulty for the it to spread because there is only a small percentage of the population left that could be infected by the disease. It is a very crucial aspect of immunity for the community as the people who cannot receive vaccinations (i.e. people with weak immune systems, very young children and patients who are too ill)

Immunizations are important to prevent diseases from spreading from person to person. If one person gets sick it can be spread it to others who are not immune. The more people who are vaccinated, the fewer opportunities a disease has to spread (CDC, What Would Happen If We Stopped Vaccinations?). The term “herd immunity” is defined as “When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease because there is little opportunity for an outbreak. Even
