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).
Healthy adults ages 18 to 29 are needed for a research study comparing the safety and effectiveness of two different vaccines for the prevention of the smallpox disease. The study will compare three dose levels of a new vaccine with the current, approved smallpox vaccine that was provided to all U.S. residents during the period of routine smallpox vaccination. The effectiveness of these trial vaccinations will be measured by observing whether or not there is a skin reaction, such as a blister, at the sight of the vaccination. A skin reaction is a typical response to smallpox vaccination. The response also will be measured by examining the size of the skin reaction and the time it takes for the blister to heal. Participants may become immune to smallpox, which would reduce or prevent infection with smallpox.
