Transplant and Regenerative Medicine Centre (TRMC)
Senior Associate Scientist
Child Health Evaluative Sciences
Dr. Upton D. Allen is a Professor of Paediatrics at the University of Toronto. He is Head of the Division of Infectious Diseases at The Hospital for Sick Children (SickKids). Allen is also a Senior Associate Scientist in Child Health Evaluative Sciences program at SickKids Research Institute. His primary appointment is with the Division of Infectious Diseases in the Department of Paediatrics at SickKids. He is cross-appointed as a professor in the Institute of Health Policy, Management and Evaluation, University of Toronto.
Dr. Allen is a past director of the Infectious Diseases Society of America and Fellow of the Society. He is a Fellow of the American Academy of Pediatrics, Fellow of the Royal College of Physicians and Surgeons of Canada and Fellow of the Royal College of Physicians (UK). In 2018, he was awarded the Order of Ontario, which is the highest honor awarded by the province of Ontario, Canada.
Dr. Allen's major research focus has been in the field of Epstein Barr virus-related disorders in transplant patients. He has studied different aspects of EBV-related post-transplant lymphoproliferative disorder (PTLD), including EBV genetic diversity in the transplant patient with a focus on the effects of viral genetic variation on EBV-related outcomes such as PTLD. This work on viral variation is integrated with related work on host susceptibility to EBV. An important output from his research on EBV PTLD will be a new clinical classification for PTLD, which is based in part on differences in survival outcomes based on sites of initial occurrence of PTLD. He has established and leads an international collaborative research group to address the consequences of genetic diversity of EBV as this relates to EBV-associated malignancies affecting children (PTLD, Hodgkin and Burkitt lymphoma).
Using the research infrastructure that he has created, he has been able to rapidly build a team to address host genetic susceptibility to COVID-19. In addition, he is leading studies addressing the immune response profiles due to COVID-19 in different age groups.

Medical researchers from SickKids are conducting largescale antibody testing and data collection to understand the prevalence of COVID-19 infection in Black Canadian communities.
Dr. Upton Allen, Head of Infectious Diseases, Senior Associate Scientist, Child Health Evaluative Sciences, and Co-chair of the SickKids-Caribbean Initiative at The Hospital for Sick Children (SickKids) was recently awarded the highest honour in the province, the Order of Ontario.
The Transplant & Regenerative Medicine Centre at SickKids is leading a global effort to develop clinical guidelines around the use of live vaccines in patients who have received solid organ transplants. This will be the first international consensus protocol on this important issue.
As the Peeks Caribbean Toronto Carnival rolls into its final weeks, The Hospital for Sick Children (SickKids) will continue to celebrate our own links with the Caribbean through the SickKids-Caribbean Initiative (SCI), a not-for-profit collaboration between the SickKids Centre for Global Child Health and key hospitals, institutions and ministries of health in six Caribbean countries to build capacity to diagnose and care for children with cancer and blood disorders.
