• As chair of the Infectious Diseases program for the Winnipeg Regional Health Authority and the section of Infectious Diseases in the Department of Medicine, University of Manitoba, Dr MacDonald holds a leadership, administrative and educational role.
• She practices mainly inpatient infectious diseases at the Health Sciences Centre in Winnipeg on the medical and surgical infectious diseases consultation services and takes after-hours call province-wide on the tele-heath system. She is experienced with immunocompromised, oncological cases and bone marrow transplantation having practiced more than 10 years as a consultant at Princess Margaret Hospital and as consultant for the biologic therapy program.
• Dr MacDonald also has particular expertise in the area of sexually transmitted infections from both a clinical and research standpoint with publications in a wide variety of bacterial and viral STI and sits on a number of public health advisory committees.
• Dr MacDonald holds the HE Sellers Research Chair in the Department of Medicine and supervises a research laboratory at the JC Wilt Infectious Diseases Research Centre of the Public Health Agency of Canada, where she is an adjunct scientist. She came to Winnipeg in 2015 from Toronto where she was previously the head of the HIV research program in the Department of Medicine.
• She has worked in the field of host immunity to HIV and its application in vaccine design for 25 years. Over the years her work has moved from an initial examination of immunogenetic susceptibility to infectious diseases to in vitro and molecular studies of mechanisms by which cellular immune epitopes may act as decoys to prevent the emergence of more protective immune responses (ref 6). Studies in the SIV macaque challenge model have demonstrated that hyper-attenuated SIV causing abortive infection can induce long term non-progressive SIV infection subsequently (ref 5).
• More recently studies utilizing both Varicella Zoster Virus (VZV) and Cytomegalovirus (CMV) as Vaccine vectors for SIV/HIV vaccines in the Cynomolgus macaque model have been conducted, the former model demonstrating that effector immune responses against SIV can induce complete control of viral load and undetectable viral load in a significant portion of vaccines and overall significantly improved viral load. Therefore promising work in both models and a preliminary human trial are continuing ( ref 1-4)
• Other human clinical trials involving the examination of mucosal immunity and the interaction between HIV and other mucosal cofactors are ongoing in collaboration with colleagues at the Kenya AIDS Vaccine Initiative, Department of Microbiology, University of Nairobi.
• Dr MacDonald supervises graduate students through the University of Manitoba (Departments of Immunology, Medical Microbiology) and the University of Toronto (Department of Immunology).

Epub, J Clin Invest. 2018 Dec 15;129(2):875-886. DOI: 10.1172/JCI124473 (Trainee Publication). Senior Responsible Author. Significant Publication. I conceived and developed the clinical trial on which this is based and am responsible for the original hypothesis which underlies the concepts that VZV provides a unique type of effector memory which would be a beneficial HIV vaccine. This paper demonstrates that this vector is safe immunogenic and does not provoke significant mucosal immune activation 12 weeks post vaccination.

Live-attenuated Zoster Vaccine Boosts VZV-specific Humoral Responses Systemically and at the Cervico-vaginal Mucosa of Kenyan VZV-seropositive Women. J Infect Dis. 2018 Sep 8;218(8):1210-1218. (Trainee Publication. Catia Perciani). Senior Responsible Author. Significant Publication. This paper demonstrates that the VZV Vector which we propose to use for our VZV-HIV vaccine not only generates excellent systemic immune responses but for the first time, demonstrates mucosal immunity at the site that HIV would challenge them. I conceptualized the study, supervised the process including the graduate trainee first author and co-wrote the paper.

PLoS One. 2018 Feb 8. eCollection 2018. (Trainee Publication. Catia Perciani). Senior Responsible Author. Significant Publication. This paper is the first to document that the rectum, cervico-vaginal and oral mucosal all have unique mucosal milieu, including a constellation of homing integrins which greatly impacts on their susceptibility to HIV infection. As senior author, I conceived the study supervised, and co-wrote the results.
