Are Vaccines safe?

Extracts from this document...


´╗┐AM Are Vaccines safe? A critical comparison AM Contents Pages 3-4 Are Vaccines Safe? Introduction Pages 5-7 For Arguements Page 8 Against Arguements Page 9 Conclusion Page 10 Bibliography Page 11 Appendix Are Vaccines safe? In this case study I shall be assessing whether or not vaccinations are safe (and whether or not the benefits outweigh the risks or vice versa) and during the course of that I will provide numerous articles, from various viewpoints and sources to justify the points that I put forward. This varies from Broadsheets such as the Independent to popular magazines such as TIME to leaflets provided by the NHS. I will also comment on the reliability of these sources and discuss its relevance to the title. I will try to maintain a neutral viewpoint when assessing and evaluating the evidence but will also add my views. ?Why do we need immunisation? The national immunisation programme has meant that dangerous diseases such as Polio have disappeared in the UK. But these diseases could come back. They areas still exist in around the world. That?s why it?s important for you to protect yourself. In the UK, diseases are kept at bay by the high immunisation rates How do vaccines work? ...read more.


Some people also think that giving the MMR vaccine rather than 3 separate diseases increases the risk of Autism (for reasons that I will discuss later in this section) ?Giving the vaccines separately at intervals means that children are not protected a disease at the earliest possible time? [3] This means that an inconvenience will be caused for both the parents in transporting their child to the hospital to get each vaccine and it will cause more distress toward the child receiving the vaccine too. But since the child isn?t protected from the infections as early as possible, the risk of infection is slightly increased. 1. Many studies have claimed that the MMR vaccine is safe and the link to Autism is false Dr. Liam Smeeth, from the London School of Hygiene and Tropical Medicine conducted an investigation involving 5,000 children and the results were as follows ?78% of the children with Autism or a PDD had received MMR, similarly, 82% of the other children had been given MMR? [4]. According to Dr. Smeeth this 4% difference ?was not significant? [4]. This suggests that the MMR vaccine is safe and a study has been undertaken by a scientist to back its safety and upon further inspection I discovered that Dr. ...read more.


or the individual themselves and a choice should be provided rather than it being compulsory. Many of my ?against? sources are relatively weak and this was because I could not gather many reputable sources that discouraged vaccines and claimed they were dangerous, many people have also said that parents who do not immunize their children are selfish and took a rather negative viewpoint on the topic rather than evaluating each individual point. The anti-vaccine movement in general was disgraced by Dr. Andrew Wakefield so topic is still generally rather controversial. But it would be very hard to provide a solid piece of evidence linking Autism and MMR as the study would take years and a certain degree of chance come into the equation as some of the people may have acquired Autism even if they had not been vaccinated. The positive effects of vaccinations far outweigh the negatives but if a parent still has doubts it should not affect the wider society due to the idea of ?Herd Immunity? that I discussed earlier and as a result would mean that the child, though not immune to the disease in question in a biological sense should be at much lower risk of infection due to the people around him being immunised. But if this gets out of hand and many parents do not vaccinate their children for any reason then these diseases could re-emerge over time. ...read more.

    They get narrower (Vasoconstriction) when you get cold. Less blood flows to the skin surface so less heat is lost by radiation. You look paler because the blood is now deeper inside the body. When it's hot, the body loses heat by: * Vasodilatation - arterioles supplying the skin get wider.

    The immune system then begins with B lymphocytes, a white blood cell each with a specific antibody to fit different antigen (5). Once the lymphocyte with the right fitting antibody meets the antigen, the lymphocyte will reproduce extremely rapidly and lots of antibodies will be made, which bind to the microorganism.
