Currently approved vaccines consist of live/attenuated microbes or specific protein/polysaccharide subunits of the targeted pathogen capable of inducing protective immunity in the vaccinated patient. The use of mRNA-based vaccines can be advantageous over classical vaccines when combatting certain infectious diseases as they can be quickly adapted to target multiple microbial serotypes, have a favorable safety profile and are cost-effective. In addition, they can be manufactured and deployed rapidly in the face of an emerging infection. The development of efficacious and commercially scalable mRNA vaccines requires overcoming of certain scientific and technical challenges, mainly (1) mRNA molecule instability; (2) inefficient entry and uptake into target cells; (3) impaired antigen translation due to induction of type-I interferons and (4) induction of insufficiently potent immune responses. Herein, we propose the development of a targeted mRNA vaccine delivery system composed of biodegradable lipid particles that ensure effective delivery of intact mRNAs (coding for antigen protein and co-stimulation factor) into immune cells and selective targeting to specific CD8+ dendritic cells using anti-XCR1 scFv to induce potent cellular immune responses. This vaccine platform will be used to prevent pseudomonas aeruginosa infection in a mouse model. This novel mRNA-based vaccine platform could provide a new modality for the prevention of various infectious diseases.

The Postdoctoral Fellowships Program is unique to the NRC. It falls under the RO/RCO classification system which uses a person-based classification system instead of the more common duties-based classification system. Candidates are remunerated based on their expertise, skill, outcomes and impacts of their previous work experience.


NRC employees enjoy a wide-range of benefits including comprehensive health and dental plans, pension and insurance plans, vacation and other leave entitlements.
Fellowships are open to nationals of all countries, although preference will be given to Canadian Citizens and Permanent Residents of Canada. Please include citizenship information in your application.
The incumbent must adhere to safe workplace practices at all times.
