Some key quotes in there to think about:

  RotaTeq costs a little under $4 a dose to make.
  Merck has sold a total of more than 24 million doses
  in the US, most for $69.59 a pop (a 17-fold markup)

  In 19th-century England, Jenner’s smallpox vaccine was
  known to be effective. But despite the Compulsory  
  Vaccination Act of 1853, many people still refused 
  to take it, and thousands died unnecessarily.

  All you have to do to get the measles is to inhabit 
  the airspace of a contagious person within two hours 
  of them being there.

There are going to be parts of this country in several years that are going to be darn dangerous to travel to as herd-immunity will be gone for several major diseases. I personally think the anti-vaccine people are way overboard.
