With Proper Planning, Selective Rather Than Mass Vaccination Can Reduce Spread of Flu, Say Physicists

ScienceDaily (Jan. 10, 2011) — During outbreaks of the flu, hospitals often reporting overcrowding, and doctors advise people who have not yet been vaccinated against flu to get their shots. Surprisingly, however, three physicists -- one from the Hebrew University of Jerusalem and two others from Michigan State University -- have developed an unconventional, theoretical strategy for intensive but limited vaccination against infectious diseases (such as flu) that would replace the practice of mass inoculation over a prolonged period.

I believe the general methodology is called "achieving herd immunity".

Reach a certain critical mass of immunity (it varies among species), and the pathogen will burn itself out naturally without having to inoculate every single member.
