So its time to say auf wiedersehen! Today I will be entering my tenth and final blog on the topics of vaccines. I hope that over this ten week period you have been able to find my blog informative and helpful. We have discussed everything on vaccines from the history of vaccines to the uses of present day vaccinations. And how vaccine have completely changed the face of modern day humanity. I hope that I have been able to inform you on the importance of complying with the vaccine schedule . I also hope that I have brought awareness to the fallacies and controversies about vaccines. If you have any questions, please do not hesitate to comment below and I will be sure to respond. Thanks all for keeping up with me and don't forget to get your flu shots this year! One great resource that I found extremely helpful while writing this blog was the CDC's website. It is filled with insurmountable information on vaccine and vaccine schedules a long with many other statistical data that could be pertinent to you and your community.

Chapter 9
Vaccines protect people from diseases. They have even been able to eradicate small pox from the earth, a disease that was once ran rampant on earth. Vaccines prevent a lot of diseases that cause death, disabilities and in the end they save money.
When we are born, we are born with the ability to develop an immune system. The immune system is composed of many cells that patrol around in our fluids, organs and other tissues looking for foreign material/antigen. When the immune system comes in contact with a foreign invader/antigen, it makes antibodies against that antigen and some of those antibodies have the ability to store memory, just in case that same invader comes around again. These are called memory cells and they serve to fight a re-infection.
Vaccines assist the immune system, because they contain certain antigens that belong to a pathogenic disease. Not to worry these antigens found in vaccine are either killed or weakened, they are not strong enough to cause disease but they certainly are enough to engage our immune system. Once we engage the immune system with our antigens from the vaccine, we make antibodies against them. And like we said before some of these antibodies form into memory cells, so if we ever get infected with that same pathogen in the future we would be able to readily fight the infection. This is a general description about the way vaccine prevent diseases. All in all, vaccines are very beneficial to humans because they allow us to fight an infection without ever actually getting the disease or feeling sick.
