Konik Horse Project Announced
In the spring of 2015, Konik horses were introduced to a World Wildlife Fund floodplain reserve in Austria. Also known as the Polish primitive horse, Koniks are short in height, ranging from 12.3-13.3 hands, compared to an average of 15 hands for an average horse. These small, semi-feral horses were bred for larger shoulders to improve their value as working horses. Since their initial introduction, the herd has grown to more than 26 animals, so this year, a group of ten Konik mares were vaccinated with SpayVac.

SpayVac is known for its single dose, multi-year contraceptive efficacy; however, no long-term studies have been conducted to determine how many years mares actually remain infertile. The longest study with horses was 4 years in duration, and mares had fertility rates of 0, 17, 17, and 17% compared to 75, 75, 88, and 100% for untreated mares. This research project will determine how long mares given a single injection of SpayVac will remain infertile.
June 3, 2020 (Victoria, BC) SpayVac for Wildlife, Inc. (SFW) announces a research collaboration agreement with the National Wildlife Research Center (NWRC) of the United States Department of Agriculture (USDA). Under this collaborative agreement, SFW has worked with USDA-NWRC to formulate a novel immunocontraceptive vaccine, using VacciMax®, for a trial in captive horses. The Bureau of Land Management (BLM) is providing the horses to be tested. Testing of this new vaccine began in May with all horses entering the study having completed their injection. This new vaccine uses our patented nanoparticle formulation in combination with Bone Morphogenetic Protein 15 (BMP-15) and Growth Differentiation Factor 9 (GDF-9) antigens. Both BMP-15 and GDF-9 are known regulators of follicular growth, and a preliminary study by Davis, et al. (2018) demonstrated effects on follicular size, ovulation rate, and estrous behavior. Long-term studies are still needed, but this vaccine may cause permanent sterility in mares, which would be a welcome fertility control option for free-ranging herds that are difficult to access. Safety and efficacy will be studied over a 3-year period in a controlled trial.
“We are excited about the opportunity to develop novel treatments for overabundant wildlife in a partnership with the USDA and APHIS. They have extensive knowledge of fertility control methods and access to horses that can be used for testing the safety and efficacy of new products.” -- Dr. Ursula Bechert, Cofounder and VP of Research and Development for SFW.
"There is a high unmet need for fertility control to manage wildlife populations," said Mr. Mark Fraker-- VP of Operations and Cofounder. "Agencies responsible for managing overabundant animal populations, such as BLM, are under pressure to reduce an exploding wild horse population and do it in a humane way."
SFW's lead vaccine candidates, SpayVac-equid and SpayVac-cervid, are expected to be submitted for approval by the EPA in 3Q 2020. SFW plans to develop an entire portfolio of novel, patented fertility-control vaccines for multiple species.
June 1, 2020 (Madison, WI) The Summit on Free Roaming Equids and Ecosystem Sustainability will be held in Cody, Wyoming at the Buffalo Bill Center of the West. This meeting is a follow-up to the successful Summit held in Reno, Nevada in 2019. The purpose is “to develop stakeholder-based comprehensive communication strategies and processes to manage free-roaming equids in concert with other public lands multiple-use objectives to achieve western rangeland ecosystem sustainability”.
During the Summit, updates will be shared from the FREES network including working group progress, new research, and policy developments. Dr. Ursula Bechert,-- VP of Research and Development for SFW, and Mr. Mark Fraker, -- VP of Operations for SFW, will be serving on a panel to discuss fertility control options as well as logistical constraints for management of feral horse populations. Participants will work with this information, as well as modeling parameters, to come up with potential horse management solutions.
Mark and Ursula have been serving as members of the FREES Population Management Working Group this past year. SpayVac offers a humane alternative to managing free-ranging horse populations for multiple years with a single injection. We’re honored to have a voice at the table.
April 14, 2020 (Victoria, BC) Rocket Builders has announced its list of top "Ready to Rocket" companies operating in British Columbia. SpayVac for Wildlife Inc (SFW) is honoured to make the 2020 list in the Lifesciences sector. To be considered companies are assessed for how likely they are to experience significant growth, draw venture capital investment or be acquired by a major player in the coming year. SFW conducts R&D and manufacturing in Victoria, British Columbia and has commercial operations in Madison, Wisconsin. SFW expects to submit its lead vaccine to the EPA for registration in the United States later this year. The company anticipates vaccine approval approximately 10 months after EPA submission and will generate revenue in 2021. SFW is applying for the indication of fertility control in (equids) feral horses and feral burros, and (cervids) white-tail deer and mule deer. Studies are on-going or have been conducted in seals, macaques, red deer, and elephants. SFW intends to develop additional vaccines using other active ingredients for wild hogs, feral cats, free-roaming stray dogs, non-human primates, kangaroos, feral camels, and feral cattle. Many of these populations are growing at 20% or more per year and societal pressure is pushing wildlife control agencies to come up with humane alternatives to slaughter. SFW's mission is to develop humane methods for controlling over-abundant wildlife using single-dose immunocontraceptive vaccines.

December 2019 (Madison, WI) SpayVac has been tested in white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus) and fallow deer (Dama dama) in four trials. Now, SpayVac pZP is being tested in a group of 25 female red deer (Cervus elaphus). They are currently being treated with SpayVac and fitted with GPS collars for a monitoring period of 2-3 years. Pregnancy status of the animals will be checked by analyzing fecal samples to identify individuals genetically and then quantify their steroid hormone concentrations. SpayVac has performed very well in the past (87-100% efficacy over 3+ years). This is a collaborative project, which also will compares behavioral differences between pregnant and non-pregnant animals.
November 2019 (Victoria, BC and Madison, WI) A collaborative study was initiated to test contraceptive efficacy in a population of free-ranging macaques (Macaca mulatta). The breeding season for these macaques is in December-March, their gestation is 5½ months long, and births typically occur in May-August. Fifty female rhesus macaques have been vaccinated. This study is a follow up to replicate positive results from an earlier trial conducted in Hong Kong. Macaques are considered to be an invasive species in some parts of the world, including Florida and South Carolina. Populations are often overabundant, which is especially problematic when they live in close proximity to humans in urban and semi-urban areas. They can cause damage to property and agriculture in addition to spreading zoonotic diseases. SpayVac’s ability to provide multi-year contraceptive efficacy with a single injection makes it an excellent option for free-ranging primate population control.
The Anthropocene is proposed as the current epoch, which is “viewed as the period during which human activity has been the dominant influence on climate and the environment”. Many wildlife species, even if they are considered endangered, are overabundant in the ever-shrinking habitat ranges they occupy. SpayVac pzp vaccine is an effective tool to manage overpopulation.
Overabundant species, even native ones, can reduce biodiversity by monopolizing resources, spreading infectious diseases, and changing species composition or relative abundance.
