Professionally-written biology case study - "Are Vaccines the Solution to Disease?"

I need a complete and professionally-written biology case study discussing the ethics and scientific advantages and disadvantages of vaccination. This case study should be around 5000+ words. There must be at least 20 scientific and journalistic references, with discussion to how reliable the source is (how bias it is, where they have collected their data etc). The case study should be in this format: Introduction Background Theory History of Vaccinations How Does the Human Body Naturally Protect Against Infection? How do Vaccines Work? Arguments For Vaccination Advantages of Vaccinations Arguments Against Vaccination Side Effects of Vaccines Disadvantages of Vaccinations Conclusion Bibliography You must be able to add things upon request, but this is unprobable and will only be small additions. I am looking for a quick, friendly person to do this for me, who is online on MSN so I can check your progress. You MUST be fluent in English. When I say fluent I MEAN fluent. I must be able to proof-read the case study before payment. You will be paid upon transaction via PayPal. I will give you a specification to look at, so you know exactly what the case study needs. It needs to have full marks. I will not accept the case study until I have verified that all points have been checked. I am looking to spend about $30-40 on this. Thanks.
