Why immunotherapy study?
-
May stop or slow recurrence and spreading of cancer
-
May help when surgery is not possible, or if chemotherapy doesn't work
-
May reverse cancer metastasis

Maggie was diagnosed with osteosarcoma in Jan 2020 and got conventional treatment plus the vaccine. She is still cancer-free.

Ranger's cancer kept on spreading, even after surgery and chemotherapy. But his tumors shrank and disappeared after the EGFR/HER2 vaccine treatment.

Codi's metastatic osteosarcoma began to disappear a month after he received the EGFR/HER2 vaccine injection. He enjoyed 3 extra years as a healthy, happy pup.
How does it work?
-
Safely activates the immune system against cancer cells that are over-expressing EGFR and HER2 proteins.
-
The vaccine has already been given to over 600 dogs. Minimum side effect reported.
-
May help with many different cancer types. Preliminary data for osteosarcoma and hemangiosarcoma published.
-

May 17, 2023 Washington State University WSU will be pausing radiation treatment from end of June until Sept as they update their linear accelerator. If you live in the Pacific Northwest and are looking for vaccine + radiation therapy option, please consult your oncologist. The veterinary hospital in Portland, Oregon is offering radiation therapy. None of the clinics in Seattle offers radiation therapy.
-
May 3, 2023 Bridge Animal Referral Center BARC in Edmonds WA is continuing to enroll patients. Call for an appointment. (It’s easiest and quickest to make an appointment if your dog is already seeing an oncologist because your dog just needs to come in for office visits for two vaccine shots plus a blood draw. If you need to set up an appointment as a new oncology patient, the wait time may be 2-3 months. By the way, there is no radiation treatment option at this clinic)

May 3, 2023 Washington State University Veterinary Hospital is accepting patients. For dogs who are not candidates for surgery. Radiation therapy + vaccine.
