Research in the laboratory of Hildegund C.J. Ertl centers on developing vaccines for an array of diseases and conditions—including AIDS and some forms of cancer—not typically considered to be treated using this approach. These vaccines aim to protect against future infections and look to create new therapies for diseases already affecting people. Projects fall into six broad categories: HIV vaccines, human papilloma virus vaccines, rabies vaccine models, universal influenza vaccine, vaccines to Epstein-Barr virus, and immune response associated with gene therapy using adeno-associated viral vectors.
Dr. Ertl came to The Wistar Institute as an associate professor in 1987. A native of Euskirchen, Germany, Dr. Ertl received her medical degree from University of Göttingen. While in medical school, she began her scientific training as a student in the Max Planck Institute of Experimental Medicine. After research fellowships at the Australian National University and the University of Minnesota, Dr. Ertl joined the faculty of Harvard University before transitioning to Wistar. She became a full professor at Wistar in 1996, and holds professorships at the University of Pennsylvania School of Medicine and The Children’s Hospital of Philadelphia.
In 2007, Dr. Ertl helped write the next chapter in Wistar’s long history of vaccine research and development with the creation of The Wistar Institute Vaccine Center, which she serves as director. The Vaccine Center unites the full expanse of Wistar’s current efforts in immunology and vaccinology with researchers around the world.
The Ertl laboratory has pioneered numerous patented technologies to create new vaccines. Much of the laboratory’s efforts on developing a new preventative vaccine for rabies—a disease that retains a disastrous presence in places across the globe—have yielded useful technologies that the Ertl laboratory is applying to combating other viruses. This includes utilizing a modified chimpanzee virus as a vaccine carrier to induce an immune response against HIV, and a new therapeutic vaccine against human papillomavirus (HPV), a leading cause of cervical cancer.
