"Vaccines developed for animals, including rabies or swine fever shots, have historically been aimed at protecting humans rather than the animals themselves.

Scientists are now increasingly looking at animal vaccines as a means of saving wild populations of threatened species.

As with vaccines for humans, development cycles can take a decade or more, and the challenge of administering doses is far more complex.

But some initiatives have shown promise in protecting wildlife from infectious diseases that could otherwise lead to entire species being decimated."
