You may remember that some of the first reported incidents of COVID-19 infection in animals were in zoo animals. These animals are at a higher risk of contracting COVID as a result of contact with handlers, veterinary staff, and the visiting public. Fortunately, a COVID vaccine was developed specifically for zoo animals.

COVID-19 Vaccine for Zoo Animals

The vaccine, which was developed by the global animal health company Zoetis, was formulated for animals and donated for emergency use among the great ape population at the San Diego Zoo in January of 2021. This sparked a good deal of media coverage which led to numerous requests for the vaccine from zoos and other animal facilities around the U.S. According to Zoetis, they have now donated a “total of 26,000 doses, to approximately 100 zoos and 20 conservatories, sanctuaries, and other animal organizations located across 41 states and about a dozen countries.”

A COVID vaccine for zoo animals is necessary for many reasons. For one, many zoo animals are endangered in the wild and keeping them healthy is of the utmost importance. Additionally, symptoms of COVID-19 can be difficult to treat in zoo animals and thus, it makes better sense to prevent the disease rather than treat it. The vaccine does not use live or inactivated virus, nor is it an mRNA vaccine. Instead, it is a subunit recombinant vaccine and is administered in two doses several weeks apart.

VetStem’s Work with Zoo Animals

At VetStem, we have worked with several exotic animal organizations, providing stem cell therapy for an array of diseases. We recently shared about our work with elephants suffering from a viral disease known as Elephant Endotheliotropic Herpesvirus (EEHV). EEHV is a lethal viral infection that affects Asian elephants and now, increasingly, African elephants and can cause a highly fatal hemorrhagic disease.

Interestingly, it was actually our human company’s work with a COVID-19 stem cell clinical trial that led to exploring stem cells as a treatment option for EEHV. We have provided stem cell doses to several zoos in the United States who had elephants with EEHV and have gathered some promising data. Stem cells have numerous mechanisms of action, including the secretion of molecules that are anti-viral.

Maintaining the health of zoo animals, particularly those who are endangered, is crucial. Veterinarians and those in the animal health field have taken a collaborative approach, making this important endeavor a community effort. We are happy to contribute to the mission and will continue our own research to develop potentially life-saving stem cell treatments for these animals.

As you may know, VetStem has worked with several wild animal organizations over the years.  One example is Francis, a Sun Bear at the San Diego Zoo who received VetStem Cell Therapy.  Like dogs, cats, and horses, exotic animals are near and dear to us.  We previously posted a blog about caring for your dogs and cats during the COVID-19 pandemic but what about the zoo animals?

Due to the current stipulations in place regarding social distancing, zoos and aquariums across the United States have closed to the public.  While non-essential employees may be working from home, the animals still need care.  The animal care staff continues to provide routine care to the best of their ability.  Non-emergency procedures have been postponed, such as preventative care and routine vaccinations, in cases where the procedures require more than one person to work closely together.  But otherwise, the care continues.

Due to interruptions in supply chains, some food sources might become scarce or temporarily unavailable.  While this might sound scary, zoos and aquariums have safeguards in place to help prevent this from becoming a problem.  For instance, the platypuses, which are currently on display at the San Diego Zoo Safari Park, are very picky eaters and prefer live crayfish.  Zookeepers are working with the animals to introduce various options into their diets, should live crayfish become unavailable.

While we continue to live in unprecedented and uncertain times, rest assured knowing the animals we love so much are being well cared for.  Zoos have said the animal caretakers are providing extra enrichment opportunities and exercises to help make up for the lack of interaction from visitors.  In fact, several zoos and aquariums have set up live broadcasts and videos showing various animals.  In one exceptionally cute video from the Shedd Aquarium in Chicago, IL, the resident penguins take a trip to meet the beluga whales.  We encourage you to check your local zoo’s website or Facebook page for fun and interactive videos.  Or you can view some of the larger zoos’ videos such as the San Diego Zoo’s Live Cams or the Smithsonian’s National Zoo Webcams.
