may no longer take surgery to prevent unwanted litters of puppies
and kittens. Herr and post-doctoral fellow Scott Coonrod are working
to develop a contraceptive vaccine for pets.
researchers are using genetically engineered proteins, which when
injected into female animals, will induce an immune response that
affects the egg and interrupts the cascade of events that occurs
during fertilization. The vaccine could reduce the number of unwanted
pets who end up abandoned or destroyed if they are not adopted
through animal shelters, Herr said. The research also could lead
to a new approach to contraception relevant to many species.
