Manufacturers of rabies post-exposure prophylaxis vaccines, used yearly to treat some 23,000 to 38,000 potentially exposed Americans, have reported low stock of the vaccines. That's concerning to health officials because this year's tally of rabies cases in animals is higher than normal and human exposures are up. "It's a little worrisome. It makes us even more cautious," said New Mexico's state public health veterinarian Paul Ettestad. "Usually we keep enough vaccine on hand for 10 people, and right now we have enough only for three or four." Production of the vaccines is under way and colder weather should slow the virus, so experts expect supplies to rebound soon.
