Abstract
Vaccines are an example of great advancements in medicine. Vaccinations have allowed dangerous diseases, such as smallpox and polio, to become rare. An article in The Lancet in 1998 discussed a study that linked the MMR vaccine with autism. Even though the study has been proven false, people continue to believe vaccines are dangerous and cause autism. This paper explores the controversy of vaccines, arguments for and against them, and any risks associated with vaccines.

However, it wasn’t until 1955, when Salk’s vaccine was released for polio, that vaccinations really become accessible and used by the public (Mnookin, 2011). Since then, vaccines have been tested and more diseases can be prevented by getting vaccinated. Vaccinations prevent serious diseases such as measles and smallpox. Overall, the purpose of vaccines are to make the body immune to an array of diseases by introducing a weak form of an disease to the immune system, thus allowing white blood cells to fight the disease and protect the body from that disease (Centers for Disease Control and Prevention, …show more content…
In the 1990s, an article was released in The Lancet by Andrew Wakefield. He composed a study of the effects of the Measles-Mumps-Rubella vaccines on children. The study suggested that the MMR vaccine can be linked to causing autism or personality disorders. The published study sparked controversy, and stopped families from taking their children to get vaccinated out of fear. Scientists and doctors quickly disproved Wakefield’s findings, claiming his work was inaccurate and fraudulent (Mnookin, 2011). However, parents continue to distrust vaccines and spread the inaccurate information about autism around to other parents who are unsure what to think about vaccines. The debate on the safety of vaccines affects every household, whether they are for or against them. Most doctors and public health officials find the idea of a parent not getting their children vaccinated immoral and potentially catastrophic (Cronin, 2007). Not receiving immunizations puts others who cannot get vaccinated at risk. Although America’s disease rate has dropped, other countries may have higher numbers of unvaccinated vaccines, showing that polio or smallpox can be spread through traveling to foreign countries or from foreigners themselves (Cronin,
In the journal of “Vaccines and Autism” author Bernard Rimland looks at the possible role of vaccines in autism. Rimland provides crucial data in understanding autism, the possible role of vaccines in autism, and the risks of vaccines in certain children. Rimland states before his article that, “There is no consensus about biological determents of autism” (708). This being said, in his journal he points out various reasons how vaccines could lead to autism. Vaccines help immunize people against certain diseases, but are they causing others? Rimland explores this question by talking about the absence of antibodies and vitamin A, vaccines containing mercury preservatives, and MMR vaccines.
The controversy over the MMR vaccine started in the late 1990’s when Andrew Wakefield suggested that there was a connection between the MMR vaccine and autism in a scientific paper which he had published with several other co-authors. Although there has not been a proven fact that the MMR vaccine is the causation to autism it has brought concerns to parents and has caused a major drop in immunization rates. For example, Dannetun et al., 2005 states that, “Fear of side effects and beliefs
Although the negative claims behind anti-immunization stances are deceptive and discredited, some parents find it difficult to accept that vaccines are necessary and safe. Many of these reasons are due to personal or religious beliefs that have persuaded parents to bypass immunizations for their children. Consequently, health officials are seeing disquieting rises of diseases that are easily preventable. The CDC (Center for Disease Control and Prevention) has reported hundreds of measles cases in the United States in 2011, the largest number in 15 years (Ben-Joseph, Elana). Essentially, almost all of these cases were in individuals who had not received a vaccine shot. Also found in the article was that a great amount of the quarrel over the shots comes from a 1998 study that tried to connect autism to a type of vaccine that defends against measles. However, there has been no scientific evidence that a vaccine or a combination of any of the shots induces autism. Undoubtedly, the doctor that wrote the article, calling vaccines a “deliberate fraud” ,lost his license for not submitting any evidence of his claim and causing people to neglect shots for that year. Sadly, due to that article, 1 in 4 parents still believe that vaccines are
In order to investigate more about Wakefield’s study, Brian Deer, a journalist of British Medical Journal, carefully talked to the parents of all children who were participated in the study. Interestingly enough, he revealed the fraud behind Wakefield’s research. The Lancet, the journal that reported Wakefield’s study, retracted the paper soon afterwards (Deer). However, the real trouble still exists. Though it has been proved by many researchers that the MRR doesn’t cause autism, many people perceive the vaccine as a threat. Dr.Nemeroff once said “it is quite difficult to get the cognitive sewage out of the water even after the real sewage is gone” (Greene).
One subject that has been very controversial for many years is the role of vaccinations causing Autism spectrum disorder in children. Since Eric Gallup was a healthy baby until he received was his first measles-mumps-rubella (MMR) vaccination in 1986. His parent noticed his behavior and ability to communicate after took the vaccinated. Eric had a serious reaction to the vaccine, according to his parent. In the year of 1989, he was diagnosed with autism spectrum disorder. Eric Gallup’s parents developed a hypothesis that childhood vaccine was responsible for Eric's autism spectrum disorder.
Recently an anti-vaccination movement has sparked a worldwide discussion about both the safety of vaccines and the responsibility of people to vaccinate. Recent outbreaks of preventable diseases have caused both fear and anger from people on both sides of the issue. These same outbreaks have also served to cause significant political tension between those against vaccines, who do not want their right to choose compromised, and many proponents of vaccines, who are calling for mandatory vaccinations.
Although there is no scientific proof that vaccines cause autism, proponents still believe that they do. The theory that vaccines cause autism were based on unproven facts and falsified information (DeStefano 81). In an article called CNS Drugs, the author writes about how a man named AJ Wakefield stun the public with a theory that the MMR vaccine may cause autism and how enterocolitis (bowel dysfunction) and MMR vaccine may be linked to autism (DeStefano 831). Even though Wakefield falsified information and his theories were proven to be discredited many people still
The topic of childhood vaccinations and the dangers that accompany them has been a topic of controversy in contemporary times. At the near edge of the twenty-first century, a man named Doctor Andrew Wakefield released a study which created a mass uproar in both parents and health professionals alike. Parents were panicked as to whether or not they should have their young child vaccinated (in fear of their acquiring autism), and health professionals fearful that the population percentage of people acquiring measles, mumps, or rubella (for it was the M.M.R. vaccination that the parents feared in particular) would rise to a number which would lead to a mass risk of disease. Despite Wakefields’ study, the truth persists in all types of experiments related to vaccination. Whether being tested in a replication of Wakefields’ study or in any other, vaccines have been proven to work at preventing disease and display no causation of autism.
Do vaccines cause autism is a question that has been bouncing around for over twenty years. The increase in the number of diagnosed cases of Autism Spectrum Disorder has increased significantly and due to the impact this has in people’s lives several studies have been done in an effort to determine the cause. More specifically the MMR, Measles, Mumps, and Rubella, vaccination has been accused of being the cause of autism. This accusation then contributed to families not vaccinating their children. Even though science disproves the link between vaccines and autism in several studies done in the United Kingdom, California, and Canada, many people cling to the vaccination-autism connection (Gerber, 2009).
One of the most controversial stories in today’s medicine is between autism and vaccinations. Autism is a disorder that makes it difficult for people to communicate with others and form relationships with them. It has been thought that vaccinations that children receive at an early age cause autism. Autism has become more prevalent over the years and scientists are still unsure how the disorder has come about. Some parents have taken it upon themselves to not vaccinate their children because they believe it will cause their child to become autistic. The real question is do vaccines really cause autism and if so which vaccine is it?
In the article, “Vaccines Cause Autism,” Michael Snyder, an attorney and writer, attempts to convince parents of young children that autism is directly linked to childhood vaccinations. He claims that numerous toxins, including thimerosal, are present in vaccines that are forced into the bloodstream, later causing neurological and brain damage to children. He says that autism has risen by 78 percent over the past decade, and that 1/88 children in the US have an autistic disorder. Snyder believes that most autistic individuals start out completely normal, and that the vaccinations they are given are harming them. He blames the pharmaceutical companies for being too
The current issue I have selected to discuss is vaccinations. In particular, I will be addressing the anti-vaccination movement that has gained popularity in recent years and the contributing biases that influenced its emergence. One event stands out at as a major contributing factor to the growth of the anti-vaccination movement, the 1998 study by Andrew Wakefield that was published by the English medical journal, Lancet. This study claimed to show a connection between the MMR vaccine and autism. Even though it was just one small study, the media picked it up and it became hugely publicized.
This led to the support of various unproven vaccine-autism theories by parents in both the UK and America. After findings of intestinal disease in children with autism, Wakefield claimed that separating the MMR into three different vaccinations would be safer. Since then, Wakefield’s research has been discredited, he was charged with serious professional misconduct by the General Medical Council for violating several ethical practices, and he was investigated for failing to disclose conflict of interest – a pending patent on a rival measles vaccine (Gross, 2009). Although false, many still believe wholeheartedly that vaccines are harmful.
“In 2011 alone, 1.5 million children died [worldwide] from diseases preventable by currently recommended vaccines” (“Immunization” 2). The magnitude of this tragedy is in part caused by the fact that some of those children simply weren’t reached by organizations like UNICEF, which aim to vaccinate children (“Immunization” 2). However, there are other reasons for the recent deaths and epidemics—such as the whooping cough epidemic of 2012, with 48,000 cases nationally in the United States—involving vaccine preventable diseases (McClay 1).
In a world that is continuously evolving, we’ve come a long way from epidemic and rampant diseases. From the Black Plague to the swine flu scare in 2009, diseases have always existed but luckily vaccines were created to mitigate or even eradicate them. A vaccine is a product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol. The first vaccines came out around the late 18th century to early 19th century with the invention of smallpox vaccines. Unfortunately, not everyone agrees with vaccines, much less mandating all vaccine. Whether or not the whole population should be vaccinated has sparked recent debates; some people have legitimate reasons and fears of vaccines while others are
