Pilot Results


What has the Fairfax County Oral Rabies Vaccine pilot program accomplished?

In spring and fall 2000, the pilot program distributed almost 40,000 oral rabies vaccine baits in the 70 square mile target area that lies east of Interstate 95 and south of the Beltway, including about 9,000 baits that were placed by the Army at Ft. Belvoir. A summary is shown in the following table May 5-24, 2000 (JPG file,90K) and  October 9-20, 2000  (JPG file,85K).

How effective has oral rabies vaccine distribution been so far?

Following each oral rabies vaccine distribution in 2000, raccoon trapping (JPG file, 68K)found acceptable levels of vaccination...37% after the spring vaccination and 45% after the fall vaccination. Other urban counties have achieved a significant reduction in the incidence animal rabies and human exposure to rabies with immunization percentages in this range, according to Dr. Francois Elvinger, Fairfax County Oral Rabies Vaccine Pilot Program Manager. To date there has not been sufficient distribution of oral rabies vaccine in Fairfax County to expect to detect a reduction in the number of persons exposed to rabies. A summary of trapping activities is shown in the following table:

Raccoon Trapping Results:

  Number of Raccoons Trapped Number of Blood Samples Number (Percent) Immunized (Titer greater than 5)
Late Fall 2000 68 66 30 (45%)
Late Spring/Early Summer 2000 92 89 33 (37%)
Fall 1999 (baseline) 55 52 1 (2%)*
