Vaccines have been around for hundreds of years starting in 1796 when Edward Jenner created the first smallpox vaccine. Jenner, an English country doctor noticed cowpox, which were blisters forming on the female cow utters. Jenner then took fluid from the cow blister and scratched it into an eight-year-old boy. A single blister came up were the boy had been scratched but it quickly recovered. After this experiment, Jenner injected the boy with smallpox matter. No disease arose, the vaccine was a success. Doctors all around Europe soon began to proceed in Jenner’s method. Seven different vaccines came from the single experimental smallpox vaccine. Now the questions were on the horizon. Should everyone be getting vaccinations? Where’s the safety limit? How can they be improved? These questions needed answers, and with a couple hundred years later with all the technology, we would have them(ncbi.nlm.nih.gov).
Since the smallpox vaccine was invented, there have been over a hundred other vaccines created. Every vaccine created goes into one of the seven types of vaccines. One type being live or attenuated, which means the vaccine contains a live virus that has been weakened or altered so it doesn’t cause illness. Attenuated vaccines are good “teachers” for the body since they’re the closest thing to a natural infection. An example of an attenuated vaccine would be the vaccination for the measles, mumps, yellow fever or the chicken pox. Attenuated vaccines can be made in several ways. Most common method involves taking the virus and putting it through series of chick embryos. When the virus passes through the embryos it loses the ability to reproduce in human cells. The only downside to the attenuated vaccine is that it doesn’t work o...

...us or bacterium used as the carrier. Recombinant vector vaccines are still being experimented on today, just like the DNA vaccinations. The only difference between recombinant vector vaccines and DNA vaccines is the fact recombinant vector vaccines use an attenuated virus or bacterium to introduce microbial DNA to the body’s cells. Scientists created this vaccine by observing nature, and how nature passes viruses along. Scientists noticed that viruses in nature latch on to the cells they want to inject, this caused scientists to figure out how to take parts of an attenuated virus and add genetic matter from other microbes into them. I know this sounds confusing, but it’s quite simple. Just think of it as poisoning the virus. Recombinant vector vaccines are very close to mimicking a natural infection, which causes the immune system to energize and start up sooner.
The authors used a historical timeline to introduce a need. Stressing the number of lives lost allows the authors show the importance of vaccines. The repeated emphasis on those lives being the lives of children played on the emotions of readers. Once the need is established Lee and Carson-Dewitt clarify the use of “a dead or mild form of a virus” to create a vaccine (Lee, Carson-Dewitt, 2016, p.2). The distinction of the types of
Vaccine safety is one of the most controversial topics in today’s public discourse. Everyone has heard of them, but few know why they are so encouraged. A vaccine contains a weak or dead version of a microbe. This creates a small scale invasion of the immune system, which activates cells to destroy the microbe. Once these cells have been made they are always there to provide protection. This protection is immunity, for those cells are then able to recognize any live version of the same microbe and attack it immediately. This can save lives but also be dangerous, vaccines carry many other components which can cause side effects. These could be simple adverse effects such as a small cold or, in the rare case,

Vaccines have been used to prevent diseases for centuries, and have saved countless lives of children and adults. The smallpox vaccine was invented as early as 1796, and since then the use of vaccines has continued to protect us from countless life threatening diseases such as polio, measles, and pertussis. The Center for Disease Control and Prevention (2010) assures that vaccines are extensively tested by scientist to make sure they are effective and safe, and must receive the approval of the Food and Drug Administration before being used. “Perhaps the greatest success story in public health is the reduction of infectious diseases due to the use of vaccines” (CDC, 2010). Routine immunization has eliminated smallpox from the globe and led to the near removal of wild polio virus. Vaccines have reduced some preventable infectious diseases to an all-time low, and now few people experience the devastating effects of measles, pertussis, and other illnesses.
The idea behind vaccines is to provide the body with just enough of the disease-causing substance to trick the body into producing antibodies against it. By injecting weak or dead infectious agents through the skin, it’s believed that the body will create the appropriate immune defense. Infants come into the world with antibodies they have gotten from their mother through the placenta. Infants who are breastfed continue to receive many important antibodies in the colostrum (the thick, yellowish premilk that is secreted during the first few days after a woman gives birth) and breast milk. During the first year of life, the immunity an infant gets from its mother at birth wears off. To help boost the fading ability to fight certain diseases, vaccines are given. Once the antibodies are produced, they stay around, protecting the child against the disease they were designed to fight.
The history of differentiating between diseases and vaccinating them is a practice that has been used for more millennia than you can count on two fingers. In 900 BC, a Persian physician named Rhazes was the first to publish a written account attempting to distinguish between measles and smallpox (successful or not is a whole other matter). It takes about 2500 years before any more development in the field of vaccination. In 1661, Chinese Emperor Kiang wrote a letter that stated that he fully supports inoculation, which is the introduction of a pathogen or antigen into a living organism to stimulate the production of antibodies. Then in 1676, English doctor Thomas Sydenham publishes ‘Medical observations on the history and cure of acute diseases’ which successfully distinguishes measles from smallpox while in great detail. The report also stated details about Scarlet Fever which was big at the time. In 1678, a Boston newspaper published America’s first medical work, Thomas Thatcher’ pamphlet: A Brief Rule to Guide the Common People of New England how to order themselves and theirs in the Small Pocks, or Measles. Once again, Thomas Sydenham discovers a medical breakthrough in 1684 by concluding that the common health practices, not available to the poor, were more harmful than good in mild smallpox cases. Sydenham’s discovery would be the last big medical innovatio...
Vaccinations are designed to help people go through their everyday lives. A country doctor, Edward Jenner, who lived in Berkeley, England, first administered vaccines in 1796 (Health Affairs). Throughout history, vaccinations have become better where they are safer for the human body. Everyone should get vaccinated against certain diseases to stay healthy. Vaccines have been proven to make people immune to serious diseases (Childhood Immunization).
Today’s day and age it is extremely important that adults, teens, and children get vaccinated. Getting vaccinated can reduce the risk of contracting a communicable disease. This makes it very important to get vaccinated because reducing the risk of contracting a communicable disease could be the difference between actually contracting the disease or not. It is important to get vaccinated because you reduce the risk of contracting certain communicable diseases, reduce the risk of people around you contracting some communicable diseases, and encourage others to be vaccinated.
DNA vaccines have been researched, and scientists are trying to find ways to put them into use and cure diseases in humans and animals. Vaccines activate the protective immunity that is an effect natural infection, without having to become sick with an infection (Paul Offit, 2014). Vaccines reduced the probability of people today to get diseases like the measles, and other major infectious diseases (Anonymous, 2011). Vaccines are not always safe, and also lots of vaccines are not always as effective as wanted (Anonymous, 2011). Edward Jenner was a scientist and physician who first introduced the smallpox vaccine in 1796(Mary Quirk, N.d). Eric Simon, Jean Dickey, Jane Reece, and Neil Campbell (1967) state that DNA is the genetic material that organisms inherit from their parents and ancestors. The information in DNA is made up of a code containing four letters A, G, C, and T (Anonymous, 2014). The order of these four letters in DNA determines how the organisms maintain its information (Anonymous, 2014). A DNA vaccine is where genetic material is injected into an organism; this can cause some of the cells to produce the gene product (Koprowski, 1998).
The discovery of the polio vaccine was an important medical and scientific breakthrough because it saved many lives since the 1950s. In the summer of 1916 the great polio epidemic struck the United states. By the 1950s hundreds of thousands of people had been struck by the poliomyelitis. The highest number of cases occurred in 1953 with over 50,000 people infected with the virus.
To fully understand the reasoning, however fraudulent, behind the anti-vaccination movement, one must first know what a vaccine is and how it works. A typical vaccine works by introducing a small, weakened version of the target virus into the system of the vaccine receiver. The receiver then fights off the inferior version, preparing the white blood cells for future attacks. In theory, this creates an immunity to the target virus. Vaccines have been proven to be the most effective method in preventing viral diseases.
Throughout the years the world has made many medicals advancements, one including vaccines. A vaccine is a substance that produces immunity from a disease, which is usually injected by a shot. Vaccines train the immune system by injected the disease into you so that when you come around the bacteria or virus again your body is able to fight it off. When the bacteria or virus enters the body immune cells attack it by producing protein molecules also knowns as antibodies. These antibodies then attack the virus or bacteria. The first immunisation known to us today happened hundreds of years ago when the Buddhist monks drank snake venom to make their bodies immune to a snake bite. However people consider Edward Jenner to be the founder of vaccinations. In 1798 He injected a thirteen year old with cowpox to demonstrate immunity to smallpox. Vaccines are extremely important because they aren’t like many other health things. For example if you don’t go to the dentist that is your own choice and it may have a big affect on you but it most likely won’t affect other people. But with vaccines it can affect the people around you as well as your community. You can catch or spread a disease in a workplace or school.
Ever since the first vaccine for smallpox was invented over 200 years ago, there has been plenty of controversy over children receiving vaccinations (Smith & Bouck, 2009). It seems to be a delicate balance between personal liberty and public health. Every parent is concerned for their child’s health and todays parents want more information. To vaccinate or not to vaccinate should be an informed choice and not one made from fear (Glanz, Kraus, & Daley, 2014). Edward Jenner invented the first vaccine for smallpox in 1796 which, according to the World Health Organization (2015), eradicated the disease worldwide by 1980. A vaccine is “a product that stimulates a person’s immune system to produce immunity to a specific disease” (CDC, 2014, para.
November begins the flu season in the Northern Hemisphere, so people have to be vaccinated. Flu shots must be taken every year unlike other vaccines that people only need to take once. But recently researchers have discovered a vaccine that protects against many other types, or strains, of the flu virus, and this might be able to lead to life lasting protection from the flu. Flu shots teach the immune system how to identify the flu virus, and that can help the body reject an infection. The flu virus evolves rapidly, and if your body does not recognize the newest version, it could infect you, so people have to get the newest flu shot every year. But researches at the University of Nebraska-Lincoln have discovered a new vaccine that might last
For innumerable centuries, unrelenting strains of disease have ravaged society. From the polio epidemic in the twentieth century to the measles cases in the latter half of the century, such an adverse component of nature has taken the lives of many. In 1796, Edward Jenner discovered that exposure to cowpox could foster immunity against smallpox; through injecting the cowpox into another person’s arm, he founded the revolutionary concept known as a vaccination. While many attribute the eradication of various diseases to vaccines, many United States citizens are progressively beginning to oppose them. Many deludedly thought that measles had been completely terminated throughout the United States.
