Influenza viruses are divided scientifically into three types, designated A, B, and C. Influenza types A and B are responsible for epidemics of respiratory illness that occur almost every winter. Influenza type C usually causes either a very mild respiratory illness or no symptoms at all; it does not cause epidemics and does not have the severe public-health impact of influenza types A and B. Type A viruses are divided into subtypes and are named based on differences in two viral surface proteins called hemagglutinin (H) and neuraminidase (N). There are 16 known H subtypes and nine known N subtypes.

With the latest round of hysteria regarding the prevalence of the annual flu season and the need for the flu vaccine in full swing, one unaccustomed to reading the details of government statistics and the arguments for or against vaccination might justifiably be terrorized into running to their local vaccine dispensary and rolling up their sleeves. Indeed, the average person encountering the reports of infection, hospitalization, and death will justifiably be stirred into a frenzied state of panic.
The vaccine makers, pharmaceutical companies, and their representatives also known as medical doctors, are, of course, waiting with open arms and needles locked and loaded. With statistics such as hundreds of thousands of infections and tens of thousands of deaths by the flu virus being repeated ad nauseam, it is understandable why many hapless individuals rush to take toxic vaccines unaware of the hazardous ingredients they contain.
However, what is scarcely examined …
The effectiveness of the flu vaccine is dependent upon the extent of the match between the virus strains used to prepare the vaccine and those viruses in actual circulation. The age and health status of the individual also play a role in determining the effectiveness of the vaccine.
