The Remarkable Story of Hunter, the Golden Retriever
How a Novel Vaccine Saved a Search-and-Rescue Dog’s Life
At 11, golden retriever Hunter was diagnosed with osteosarcoma, a tough bone cancer. The usual survival rate was low, around 65%. But, Hunter’s story changed when his owner, Deana Hudgins, signed him up for a Yale University vaccine trial.
Hunter was more than just a pet; he was a search-and-rescue dog. He helped find people trapped in disasters. After his cancer diagnosis, Hudgins tried standard treatments like amputation and chemo. Yet, she wanted to try the Yale vaccine, a new immunotherapy for canine cancer.
“When Hunter was diagnosed, I knew I had to do everything in my power to help him,” said Deana Hudgins. “The Yale vaccine offered hope, and I was willing to try it, even if it meant putting Hunter through additional treatment.”
Now, two years post-diagnosis, Hunter shows no signs of osteosarcoma. He still helps Hudgins train other search-and-rescue dogs. His story highlights the success of the Yale vaccine and the hard work of researchers like Mark Mamula.
Unlocking the Potential of Comparative Oncology
The Yale vaccine for dogs comes from comparative oncology and translational medicine. These fields use findings from different species to improve human medicine. Dogs and humans have similar cancers and molecular mechanisms behind them.
For example, dogs and humans both have cancers that overexpress proteins like EGFR and HER2. By studying dog cancer, researchers can learn new things that might help humans. This teamwork between human and vet medicine could lead to new cancer treatments.
The American Kennel Club Canine Health Foundation has funded over 30 cancer studies in dogs in 15 years. Twenty universities are working together in the Comparative Oncology Trials Consortium. They share their findings and work on clinical trials.
| Statistic | Value |
|---|---|
| Preliminary studies on the drug Verdinexor | Over 30% of dogs experienced some regression of the disease when treated |
| Researchers are starting human trials on drugs like Sutent and PAC-1 | After successful results from studies conducted on dogs |
| Dogs suffering from lymphoma | Usually receive chemotherapy infusions weekly, but Verdinexor offers a less traumatic treatment option that can be given at home |
| The Veterinary Cancer Center in Norwalk, CT | Reported that 20 dogs in a cancer study are still alive, attributing their longevity to a vaccine developed at the Yale School of Medicine |
Veterinary oncology is changing to help dogs with cancer live better lives. The Oncology Models Forum met on December 5 and 6, 2023. It focused on sharing info and working together to use animals in cancer research.
“The collaborative approach between human and veterinary medicine holds great potential for unlocking new frontiers in the fight against cancer.”
Understanding the Mechanisms Behind the Yale Vaccine
The Yale vaccine for dogs targets key proteins in canine cancer. These proteins, EGFR and HER2, help cancer grow and spread. They are found in cancers like colorectal, breast, and osteosarcoma.
Traditional treatments use monoclonal antibodies to block these proteins. But the Yale team, led by Dr. Mark Mamula, wanted to try something new. They aimed to create a polyclonal immune response. This means making many different antibodies that can attack various parts of the proteins.
Targeting EGFR and HER2 Overexpression in Canine Cancers
This vaccine is made to fight against resistance that can happen with other treatments. By creating many antibodies, it hopes to stop cancer from becoming resistant. This could make it more effective in treating dogs with cancer over time.
In tests, dogs with EGFR-related tumors got the vaccine. After, their bodies made antibodies that could attach to both dog and human EGFR on cancer cells. Dogs with osteosarcoma even saw their tumors shrink and lived longer.
“The study aimed to induce a polyclonal anti-EGFR/HER2 tumor antigen response by vaccine therapy in spontaneous EGFR expressing tumors in companion dogs.”
Collaborating for a Cure: The Journey of Mamula’s Research
Mark Mamula, a professor at Yale School of Medicine, didn’t plan to make a cancer vaccine for dogs at first. He was studying autoimmune diseases like lupus and Type 1 diabetes. But, a meeting with a vet oncologist named Gerry Post made him think about cancer research for dogs.
Mamula and Post saw how similar human and dog cancers are. They started a study on a dog cancer vaccine. Mamula’s team, including Hester Doyle and Renelle Gee, tested many compounds. They found the right mix and began the first trial in 2016.
This work brought together human and vet medicine. It led to the Yale vaccine, which has helped hundreds of dogs with cancer.
| Key Statistics | Findings |
|---|---|
| Osteosarcoma in Dogs | – Osteosarcoma is the most common primary bone tumor in dogs, representing 85% to 98% of all bone tumors. – Appendicular osteosarcoma, the most common malignant primary canine bone tumor, is typically found in large to giant dog breeds. – Median survival times for dogs with appendicular osteosarcoma treated by amputation or tumor removal alone do not exceed 5 months, with the majority developing metastatic disease. |
| Vaccine Performance | – The vaccination treatment developed by Yale researcher Mark Mamula has shown effectiveness in hundreds of dogs, including Hunter the golden retriever, who now has no evidence of bone cancer after therapy. – Mamula’s vaccine has demonstrated promising results in numerous clinical trials affecting over 300 dogs, with survival rates at approximately 35% to 60% and instances of tumor shrinkage. |
| Vaccine Design | – Mamula’s innovative vaccine aims to trigger a polyclonal immune response by generating antibodies from multiple immune cells, potentially reducing the development of resistance and enhancing treatment effectiveness. |
| Clinical Trials | – Mamula’s research team reports notable improvement in 12-month survival rates for dogs with varying types of cancers. – Mamula’s invented vaccine is undergoing multiple clinical trials at 10 locations in the US and Canada, with the first trial conducted in 2016. – Once approved, Mamula plans to offer the vaccine for free to working dogs similar to Hunter. |
This work by veterinary oncologist Gerry Post and Yale researcher Mark Mamula has led to the Yale vaccine. It has helped hundreds of dogs with canine cancer.
Promising Results from Clinical Trials
The Yale vaccine for dogs has been tested for eight years, and the results are very encouraging. In an early study, dogs with osteosarcoma, a tough bone cancer, did well. 65% of dogs that got the vaccine and standard care like amputation and chemo were alive after a year. This is way better than the usual 35-40% survival rate with just standard care.
Also, many dogs in the yale vaccine clinical trials saw their tumors shrink. This is a big deal in fighting canine cancer. Now, the trials are in 10 places across the U.S. and Canada, helping over 300 dogs with the vaccine.
Improved Survival Rates and Tumor Shrinkage
The research team is still looking into how well the vaccine works. But, the early signs are good. This new immunotherapy approach could really help dogs with different cancers, like osteosarcoma and other canine cancer treatment options.
| Metric | Standard Care | Yale Vaccine + Standard Care |
|---|---|---|
| 12-Month Survival Rate | 35-40% | 60-65% |
| Tumor Shrinkage | Limited | Significant |
The results from these trials are really promising. The researchers are excited about the Yale vaccine’s potential for treating canine cancer.
The Future of the Yale Vaccine for Dogs
The yale vaccine for dogs is showing great promise in clinical trials. It nearly doubles the survival rate for dogs with cancer. This is a big step forward in fighting this tough disease.
After getting USDA approval, the vaccine will be used more widely. Dr. Joanna Mamula, the lead researcher, plans to give it free to working dogs like search-and-rescue dogs. These dogs, like Hunter, inspired the vaccine.
The team is also looking at using the vaccine for cats and maybe even humans. The success with dogs could lead to better treatments for cancer across species.
“The Yale vaccine for dogs has the potential to revolutionize the way we approach cancer in both veterinary and human medicine,” said Dr. Mamula. “As the vaccine becomes more widely available, it will offer a beacon of hope for pet owners and their furry companions facing the devastating impact of cancer.”
The vaccine is under review by the USDA and could be approved by April. This could change how we treat canine cancer. It could become a new standard of care for pets and their families.
Canine Cancer: A Growing Concern
Canine cancer is becoming a big problem, with about one in four dogs getting the disease. For older dogs, this number goes up to almost one in two. The most common cancers in dogs are melanoma, breast cancer, colon cancer, and osteosarcoma. These cancers are similar to some in humans. But, there aren’t many new treatments for these cancers.
Exploring Immunotherapy as a Treatment Option
Researchers like Mamula are looking at new ways to treat cancer, like immunotherapy. The Yale vaccine is a new approach that targets cancer proteins in dogs. It could greatly improve treatment outcomes for dogs with cancer, giving pet owners hope.
The Yale vaccine has shown great promise in tests. It helped 65% of dogs with osteosarcoma live for a year, compared to 35-40% without it. The main side effect is a small, harmless cyst at the injection site that goes away in a few weeks.
To join the study, dogs don’t need a tumor sample. They must meet certain criteria and pass exams. The vaccine is designed to help dogs and humans fight cancer together.
The Yale vaccine is still being tested and developed, but it gives hope to pet owners. It could greatly improve survival rates and offer a new way to treat cancer in dogs. This vaccine is a big step forward in fighting canine cancer.
Overcoming Resistance: A Novel Approach
In the fight against canine cancers, treatments like monoclonal antibody therapies often hit a roadblock – drug resistance. Mark Mamula and his team at Yale have found a new way to beat this challenge.
They’re not using just one type of antibody. Instead, they’re aiming to create a polyclonal immune response. This means making many different antibodies that can attack cancer cells from various angles.
- This method makes it harder for cancer cells to become resistant to treatment.
- It could lead to a more lasting and effective way to treat dogs with cancers that have EGFR and HER2 proteins.
The team at Yale is working hard to make this new approach a reality. They want to help dogs live longer and better lives. They’re focused on fighting drug resistance and giving hope to pet owners.
“By inducing a polyclonal immune response, we aim to create a more resilient and long-lasting defense against the ever-evolving nature of cancer cells.”

Working together, human and veterinary medicine have made big strides in canine cancer research. They’re finding new treatments that could help both animals and humans. This teamwork could lead to new discoveries in translational medicine and fight cancer more effectively.
The Impact of the Gut Microbiome
The research on the Yale vaccine for dogs is looking closely at the gut microbiome. It’s studying how it affects cancer susceptibility and immunotherapy response. In dogs and humans, the gut microbiome is linked to cancer and how well treatments work.
The human body has nearly 40 trillion microorganisms, mostly in the gut. When these microorganisms get out of balance, it can lead to health issues, including cancer.
The Yale team is looking into how the gut microbiome affects cancer risk and treatment success. They’re doing comparative studies to understand these complex relationships. This could lead to better cancer treatments for humans and pets.
Studying the gut microbiome in dogs and humans could change cancer treatment. As research goes on, we might see more effective and tailored treatments. This would help both our pets and ourselves.
“The bacteria composition in the gut affects cancer risk and treatment success.”
The link between the gut microbiome and cancer susceptibility and immunotherapy response is still new but exciting. By understanding this better, we can develop better treatments for dogs and humans.
Common Side Effects and Safety Considerations
The Yale vaccine for dogs is showing great promise against canine cancer. Dog owners need to know about possible side effects and safety tips. A common side effect is a small, harmless cyst at the injection site, like a marble. This usually goes away in 1-2 weeks.
Most dogs in the clinical trials have tolerated the vaccine well. But, each dog is different. The vaccine might not help, could improve life quality, or even cure the cancer.
Talking often with vets and knowing about possible side effects is key for dog owners looking at this new cancer treatment. The yale vaccine for dogs has shown strong results, but safety and effectiveness can vary for each dog.
| Potential Side Effects | Incidence Rate |
|---|---|
| Injection site cyst | 8% (4 out of 49 dogs) |
| Nausea, lethargy, fever | Most common adverse events observed |
| Metastatic disease prior to vaccination | 10% of dogs |
| No prior treatment before vaccination | 12% of dogs |
The canine OSA vaccine (COV-LLV), also known as the Yale vaccine, got conditional approval in 2017 from the USDA. It’s important for dog owners to think about the pros and cons. They should talk with their vet to see if the Yale vaccine is right for their pet.
“Maintaining open communication with veterinary professionals and being aware of the possible side effects and safety considerations is crucial for dog owners evaluating this innovative cancer treatment option.”
Comparative Outcomes: Standard of Care vs. Vaccine
In early trials, the Yale vaccine for dogs with osteosarcoma showed big differences. Dogs getting the vaccine treatment along with standard care lived longer than those with just standard care. The vaccine group’s 12-month survival rate was 65%, while the standard care group’s was around 35-40%.
This big jump in survival times shows the vaccine’s promise. It could make cancer treatments for canine patients more effective. Many dogs on the vaccine also saw their tumors shrink, proving the vaccine’s positive effect.
The Yale team is now working to understand why different dogs and cancer types react differently. They want to make the vaccine work even better for more dogs.
| Treatment Approach | 12-month Survival Rate |
|---|---|
| Standard of Care (Amputation + Chemotherapy) | 35-40% |
| Standard of Care + Yale Vaccine | 65% |
The table clearly shows how adding the Yale vaccine to standard care greatly improves survival rates for osteosarcoma dogs. This highlights the vaccine’s potential to change how we treat canine cancer.
“The Yale vaccine has the potential to truly transform the way we approach canine cancer treatment. The significant increase in survival rates is a testament to the power of this innovative approach.”
