SpayVac is partnering with BioVaxys Technology Corp. to field test single-injection, long-lasting immuno-contraceptive vaccines in farmed rainbow trout, the organization announced today.

“We’ve been focused on developing vaccines to help manage free-ranging populations of animals like horses and deer, so this is an exciting new venture for us,” SpayVac Vice President of Research and Development Ursula Bechert said in a statement.

According to a release, SpayVac is using BioVaxys’ patented liposome-based antigen delivery platform technology.

The company plans to commercialize humane fertility control vaccines for deer, horses and other animals.
