Outline• Introduction

• Process for vaccine development

- engagement of multiple partners

• Landscape

- VIDO, CAIRE,CCV

• Opportunities

• Challenges

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

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)

Canadian Association for

Immunization Research and

Evaluation

(CAIRE)

A UNIQUELY CANADIAN INNOVATION

CAIRE Members

>140 Canadian researchers and stakeholders from more

than 30 institutions across Canada, representing a majority

of those involved in translational research

Members include leading specialists in infectious diseases,

public health, microbiology, clinical trials, vaccine

immunology and technology assessment, social and

behavioral science, nursing research, epidemiology,

In 2012 CAIRE brought Canadian vaccinology

stakeholders (industry, public health, academia)

together to discuss how to enhance partnerships in

vaccine-based disease prevention

2013 Workshop on improving access to recommended

but non-funded vaccines

CAIRE Research Education

Some of CAIRE’s research education initiatives have

included:

Co-developing the Canadian Immunization

Conference to ensure ample vaccine science

Master Classes on Intelligent vaccine and program

design

Round Table on Meningococcal disease prevention to

identify research priorities

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).
