Influenza is an infectious illness that can be spread from one individual to the next. It can be transmitted by means of saliva, nasal secretions, feces and blood. It can also be spread by coming in contact with the virus on contaminated surfaces. Influenza is responsible for an average of 36,000 deaths and for more than 226,000 hospitalizations each year in the United States. (Davidson, 2007-2009, Davis, 2007). It is my goal for this paper to explain how flu vaccines are made, how long it takes to create the vaccines, and when they will be ready for distribution for the upcoming flu season. I will also present some exciting new research that may provide for a newer, faster method for making flu vaccines that would enable the vaccines to be ready and available in less than the traditional eight months. Influenza viruses are divided into three classes. These are A, B, and C. It is influenza viruses A and B that are the most virulent and responsible for causing outbreaks of the flu every year. Influenza virus C, on the other hand, produces only a very mild respiratory infection or no symptoms at all and does not pose a severe public health threat. The aim of receiving an annual vaccine is to prevent spreading infections. Because flu outbreaks fluctuate, it is recommended that individuals receive a vaccination for the flu every year, especially for those at high risk for developing serious complications from influenza infections. (Davidson, 2007-2009, Davis, 2007). Vaccines are created using several different methods. However, all vaccines share a similar general goal. That is to weaken the virus or bacteria in a manner that enables the recipient to develop an immune response against the virus at the same time avoiding any s... ... middle of paper ..., 2007).
