Vaccine research and development priorities

Canada has identified a set of priorities for research and development of new and improved human and animal vaccines. Learn about these priorities and how they are used to ensure the health of Canadians.

Stages of vaccine research and development priorities

The priorities created for vaccine preventable diseases for both human and animal health follow a 3 stage process.

First stage

The first stage identified pathogens and diseases of greatest concern to public health. They were evaluated against a range of criteria, including:

An initial set of candidate priorities was reviewed by expert groups, including the:

Based on this input, a more specific list of priority pathogens and diseases was created for further review.

Second stage

The second stage defined relevant themes on which to focus vaccine research and development for priority pathogens and diseases. Canada's research community and vaccine industry consider these themes when creating their specific innovation strategies and work plans. This is in response to emerging needs and opportunities.

There are 4 areas of focus, identified below.

  1. Microbial threats to the Canadian health system and the health security of Canadians.
  2. Protecting children and vulnerable populations.
    • Research in this area could include the protection of vulnerable groups against serious diseases such as tuberculosis.
    • It could also include more serious childhood infections such as pertussis, also known as “whooping cough.” The effectiveness of the pertussis vaccine could be improved by new technologies.
  3. Threats to the productivity, competitiveness and sustainability of Canada's agriculture and agri-food sectors.
    • Research could help control or eliminate animal diseases, especially those threatening the economic stability and viability of Canada’s agricultural sector.
  4. Supporting technologies that improve vaccine effectiveness and availability.
    • This could include research into different production techniques that will allow vaccines to be delivered to Canadians much faster. An example is changing from egg-based vaccines to plant-based ones.
    • It could include the use of adjuvants to improve immune response.
    • It could also include the development of better biomarkers for safety and immune response.

Third stage

The third stage classified the pathogens and diseases into:

Classification was based on the current state of scientific knowledge and research, and development investments. This will allow researchers to focus their activities and efforts on areas such as:

Rated vaccines included those that provide protection against diseases that currently have no vaccine. Also included are diseases that currently have a vaccine but a more effective vaccine is sought after. An improved vaccine could provide broader or longer term protection or require fewer doses for optimal protection.

Vaccines could have been given a lower priority because of:

It is important to note that this list is evergreen. Further changes may be based on need and opportunities to prevent or reduce the burden of diseases in Canada.

Human health vaccine priorities

The criteria used to assess the human pathogens and diseases include:

Other criteria could affect antimicrobial resistance and protection of vulnerable populations.
