Clinical Study Status

EGFR/HER2 Canine Cancer Vaccine 

This therapeutic vaccine, a type of immunotherapy, is now available to patients in a new clinical trial, thanks to your generous support 

Potential benefits of cancer immunotherapy for pups

  • May stop or slow recurrence and spreading of cancer

  • May help if surgery is not possible, or surgical margins were not clean

  • May help without chemotherapy, or if chemotherapy didn't work

  • May reverse cancer metastasis

  • May be safer with fewer side-effects

Maggie was diagnosed with osteosarcoma in Jan 2020 and got conventional treatment plus the vaccine.  Her cancer did not spread and she is still cancer-free.


Ranger's cancer kept on spreading, even after leg-amputation and chemotherapy.  His cancer shrank and disappeared after the Yale vaccine treatment.


Codi's metastatic osteosarcoma began to disappear a month after he received the Yale vaccine injection. He enjoyed 3 extra years as a healthy, happy pup.

Limitations and challenges

  • Does not help 100% of dogs 

  • More research needed to find out why some dogs become long-term survivors while others do not

  • New combination therapies hold promise for increasing the % of dogs responding to immunotherapy
