Why infectious diseases?• Approximately 1/3 of all annual deaths are
directly due to infectious diseases
• Some cancers caused by infectious diseases
- liver cancers -- HCV, Hep B
- cervical cancer -- HPV
• 30 new emerging or remerging diseases occurred over last 30 years- many are zoonotic
• Animal diseases threaten global food security
![Page 4: Vaccination: Canada’s leadership over the last century · applied vaccinology research in Canada Participants include academic investigators, public health leaders and representatives](https://reader035.fdocuments.net/reader035/viewer/2022062920/5f02e8c27e708231d4069cb4/html5/thumbnails/4.jpg)
Global challenges• Currently 1 billion people go to bed hungry
• By 2050 2 billion more people
• Decreased land resources/climate change
• Livestock a reliable source of income/protein
• Increase production of milk ,meat and fish
• 500 million smallholders support 2 billion
• Almost 2/3 of poor livestock keepers are women
• Healthy animals=healthy food=healthy people=
Increased economic stability

Economic impact of animaldiseases
• BSE- UK $ 1 billion direct compensation
• BSE – Canada $ 8 billion total losses
• BRD - $ 1 billion annually
• Scours $ 500 million annually
• FMD 2001 $ 6 billion
• Emerging diseases unknown
- SARS $ 100 billion

Infectious Diseases Spread Easily
• Canadians remain at risk

Canada has played a pivotal role in global vaccine development
• Paralytic Polio: Connaught laboratory– Medium 199 & Toronto Method
– Large scale production of polio vaccine
• 1st combined vaccine (DPT)
• 1st infant Meningitis C vaccine (NRC)
• World first genetically engineered animal vaccine ( VIDO)
• 1st zoonotic vaccine (VIDO-InterVac)
• Protein misfolding vaccine development
• Ebola (NML)

Vision
To develop, implement and evaluate vaccines for infectious
diseases that have a significant impact on Canadian and global
health, and to train experts in these critical fields. This is
achieved through strength in discovery science, evaluation
research, and health policy and translation through the applied
study of the social sciences and humanities (ethics, law, and
society).
