Drug shortages are becoming an increasing problem across the U.S., and many are blaming pharmaceutical companies.

Due to a shortage of tetanus shots, hospitals have begun rationing, saving them for critically injured patients and burn victims.  According to CNN.com, the shortage has so far affected only the adult version of the vaccine; children's shots are still plentiful.  Tetanus shots were already on the verge of scarcity when one of the major manufacturers, Wyeth-Ayerst, announced that they would no longer make the vaccine.  The sole remaining manufacturer has been working night and day to produce the vaccine, but the shortage is not expected to ease before the end of the year
