Vaccines Ruined by Poor Refrigeration

DES MOINES, Iowa (AP) -- Every year, thousands of American children go through the tearful, teeth-gritting ordeal of getting their vaccinations, only to be forced to do it all over again. The vaccines were duds, ruined by poor refrigeration. It is more than a source of distress for parent and child. It is a public health threat, because youngsters given understrength vaccines are unprotected against dangerous diseases. And it accounts for a big part of the $20 million in waste incurred by the federal Vaccines for Children program.
