Regarding this topic, here is a quote from a report in the most recent edition of American Association for Advancement of Science's journal Science, a journal of the highest scientific standard:
"Pandemic influenza a (H1N1) 2009 (pandemic H1N1) is spreading through the planet. It has become a dominant strain in the Southern Hemisphere, where the influenza season has now ended...on the basis of reported case clusters in the United States, we estimated the househeld secondary attack rate for pandemic H1N1 to be 27.3%...From a school outbreak, we estimated that a typical schoolchild infects 2.4 other children within the school...If a vaccine were available soon enough, vaccination of children, followed by adults, reaching 70% overall coverage, in addition to high-risk and essential workforce groups, could mitigate a severe epidemic."
This means that H1N1 spreads faster in schools than at home. One person infecting 2.4 people means exponential growth.
70% vacine coverage, which means 7 out of 10 people getting vaccinated, could mitigate a severe epidemic.
The point is, there is a bigger picture that needs to be considered when deciding whether or not to seek the vacination. Mitigating an epidemic seems like a pretty good reason to get vacinated.
