Picture of D. Lorne Tyrrell

Discovered the first oral treatment for hepatitis B and opened pathways of research for the treatment of other viral infections

Portrait of Lorne Tyrrell

Internationally recognized expert of hepatitis B (HBV)

An exceptional teacher, compassionate physician and accomplished researcher, Dr. Tyrrell has positioned the University of Alberta and Canada as a world leader in terms of hepatitis research and treatment. Aware of the similarities between duck and human hepatitis B viruses, he proposed Pekin Duck liver cells as an inexpensive model system to test HBV inhibitors. Due to his groundbreaking research, Lamivudine or 3TC was discovered to dramatically decrease HBV replication by up to 99.9%. It would become the first antiviral therapy drug for the treatment and control of HBV.

Key Facts

As a result of his discovery of Lamivudine, liver transplantation programs for hepatitis B carriers were reinstated

Developed a rapid diagnostic method for Epstein Barr Virus infections

Authored 150 peer-reviewed publications and awarded 10 million dollars in competitive research grants

Established the Glaxo-Heritage Research Institute at the University of Alberta, one of the most successful partnerships between academia and the pharmaceutical industry

Named as one of Alberta’s 100 Physicians of the Century in 2005

Played an important role in the creation of CIHR by serving on the initial task force

Professional timeline

Impact on lives today

Hepatitis B was once the tenth most common cause of death in the world. Prior to 1980, the only way to protect a person against Hepatitis B was to vaccinate and no treatment existed for those who already carried HBV. The ground-breaking work of Dr. Tyrrell has saved many lives and provided insight into other viral diseases in the hopes that many more will be aided in the future. Dr. Tyrrell spent the majority of his career contributing to Canada’s scientific excellence and ensured that others would be able to follow. In 2010, he secured the largest donation ever received by the University of Alberta, enabling him to found the Li Ka Shing Institute of Virology.

  • Lorne Tyrrell inducted into the Canadian Medical Hall of Fame

    London, Ontario

  • Dr. Tyrrell’s hepatitis studies extended to hepatitis C, where, with two colleagues, he developed another model system, an immunodeficient mouse with a humanized liver

    Infectious Disease, Allergy & Immunity

    Hundreds of compounds could now be tested as potential drugs against hepatitis C.

  • Lamivudine was licensed in Canada as Heptovir

    Infectious Disease, Allergy & Immunity

    The drug was shown to forestall HBV’s life-shortening complications, transmission, and reinfection after liver transplantation.

  • Began his 10-year term as Dean of Medicine at the University of Alberta

    Under his leadership, medical research space tripled, the Mazankowski Heart Institute was created, and Dentistry and Indigenous MD programs were reviewed.

  • Early Lamivudine drug trials began

    Infectious Disease, Allergy & Immunity

    Lamivudine was discovered to decrease the viral count in the circulating blood by over 99%.

  • Dr. Lorne Tyrrell and his team discovered a new series of anti-viral compounds that had therapeutic potential for HBV treatment

    Infectious Disease, Allergy & Immunity

    Lamivudine became the first oral anti-HBV drug for the treatment of HBV carriers.

  • Returned to the University of Alberta as an Associate Professor in Infectious Disease and Biochemistry

    He later took on more leadership roles as the Director of Infectious Disease and the Chair of the Department of Medical Microbiology and Infectious Disease.

  • After completing his PhD, pursued post-doctoral training

    He became a fellow of infectious disease at the University of Alberta and then travelled to Sweden to study at the Karolinska Institute in Stockholm.


He has infectious enthusiasm.
