Revolution in dog sterilization: Chile creates first reversible vaccine

Chilean academic Leonardo Sáenz, from the Faculty of Veterinary and Livestock Sciences (Favet) of the University of Chile, has developed the first vaccine to sterilize dogs without the need for surgery, offering a reversible alternative with no side effects.

The vaccine, called EGALITTE, works by blocking the hormone that controls reproduction in animals, allowing owners to opt for a temporary or permanent solution according to their needs.

This advance is presented as an innovative response to traditional castration methods, with an estimated cost of 50,000 Chilean pesos (US$55). The vaccine has already been patented in 40 countries and will be available in veterinary centers in Chile.

The objective of this vaccine is to facilitate the control of the canine population, providing a more accessible and less invasive option, backed by scientific studies that guarantee its safety and efficacy.
