Assessing the Costs and Benefits of an Oral Vaccine for Raccoon Rabies: A Possible Model
|Baiting scenario||NPV without pet vaccination ($ millions)
||NPV with pet vaccinationsa
|Entire area at onceb||-21.3||-15.7||-13.3||-0.5||-1.1||-1.3|
|Entire area done at once||-30.8||-21.9||-18.2||-12.5||-8.9||-7.3|
|No baiting of boundary|
|Entire area at once||+2.9||-0.9||-2.3||+23.7||+13.7||+9.7|
a) Cost savings (benefits) of 11 pets/sq. mi during an epizootic period, and 2.75 pets/sq. mi during the post-epizootic period, both at $16/pet.
b) Expanding circles assumes start with 20-mi radius, expanding by 5 mi every 2 years for 20 years, and then baiting a 5-mi wide boundary for next 10 years. Entire area assumes baiting 65-mi radius for 2 years, followed by 28 years of baiting 5-mi wide radius.
c) Ratio of distribution costs:cost savings is 1:1.03,based on New Jersey data (1). In baseline scenario, ratio is 1:1.57.
