Vaccines Are Good Business for Drug Makers By Andrew Pollack

For older vaccines used to prevent childhood diseases like mumps, measles and diphtheria, for example, more than half the doses are purchased by the federal Vaccines for Children program. Prices are capped so they rise no faster than inflation. At $10 to $30 a dose, such vaccines are not a growth market, which helps explain why there is only a single supplier for five of the eight recommended childhood vaccines and why periodic shortages still occur...

The most important factor for a healthy business is making money. Who 'da thunk?
