Oh come on, please don't try the guilt trip thing. If the flu can be spread by those who didn't get the flu shot to people who DID get the shot, then that shot was pretty darn ineffective. Isn't the whole point of the shot to prevent you from getting the flu in the first place?
Just makes the flu shot sound like even more baloney.
It makes me sad that on a tech site, there are so many scientifically illiterate individuals, especially when it's already been stated in the thread that what they appear to believe is incorrect.
It has been known for a long time that the flu shot isn't 100% effective. It's usually about 60-70% effective.
Hmmmm... I'll attempt to explain using an analogy. The mathematical models are somewhat similar. Let's turn to nuclear bombs. I think just about everyone has heard of "critical mass" - below which, you're not getting a boom. Above which, bad shit starts to happen. It's similar to that in the population. If below a certain percentage of the people are vaccinated (and really, the vaccination is only affective about 3 to 4 out of 5 times), then the flu spreads very rapidly and infects a high percentage of individuals. This results in more people (young, elderly) dying from the flu. But, if the percentage of the population that is successfully vaccinated is high enough, then the flu spreads, but not as rapidly, and not infecting as high a percentage of the population.
