Annual dog vaccines may not be necessary

Once a year, Ronald Schultz checks the antibody levels in his dogs’ blood. Why? He says for proof that most annual vaccines are unnecessary. Schultz, professor and chair of pathobiological sciences at the University of Wisconsin-Madison School of Veterinary Medicine, has been studying the effectiveness of canine vaccines since the 1970s; he’s learned that immunity can last as long as a dog’s lifetime, which suggests that our “best friends” are being over-vaccinated. Based on his findings, a community of canine vaccine experts has developed new veterinary recommendations that could eliminate a dog’s need for annual shots. The guidelines appear in the March/April issue of Trends, the journal of the American Animal Hospital Association (AAHA).

Facing disfigurement in 2002

With all the discussion about possible smallpox bioterrorism attacks in the U.S., has the dermatology world begun to address the cosmetic implications that an outbreak would entail? Sure, it sounds petty when lives are at stake. But if thousands of people stand to potentially become infected, has medicine developed any better means of preventing disfigurement? Drainage? Lots and lots of aloe gel? Sedatives to keep people doped until the pustules pass?

Smallpox immunity lasts longer than thought

A new study suggests smallpox vaccine immunity may last far longer than expected. Scientists had believed that the vaccine generally only conferred protection from the deadly virus for about a decade. But a study released this week found evidence that people may be covered for 35 years or more, meaning many Americans could retain some level of immunity. The study looked at blood samples from laboratory workers who had been immunized in the last five years and those who had been vaccinated up to 35 years earlier.
