Scientist Immunology/Bacteriology

Vacaturenummer: A2100030
Janssen Vaccines & Prevention - Leiden (Nederland)

For our client, Janssen Vaccines & Prevention, we are looking for a Scientist Immunology/Bacteriology.


  • PhD
  • Immunogenicity testing
  • Bacterial vaccines
  • Assay development
  • Certified to work with animal models

Within the Bacterial Vaccine department, the Immunology group evaluates the immunogenicity and efficacy of potential vaccine candidates against several bacterial diseases in animal models. Assays to examine humoral and cellular immune responses will be developed and used to generate appropriate scientific data to show proof of concept and thereby enabling vaccine candidates to progress towards clinical phase evaluation.
We are looking for a motivated scientist, who loves challenges, to evaluate the immunogenicity and efficacy of potential vaccine candidates. The role requires knowledge of immunological techniques such as ELISA, killing assays, Electrochemiluminescence assays (ECL), B- and T-cell ELISPOT, proliferation assays, cytokine release assays, intracellular cytokine staining, FACS analysis and cell culturing. You will be responsible for the development and implementation of new assays to measure immune responses of various bacterial vaccine candidates. In addition, it is important to have experience with designing and evaluation of pre-clinical in vivo models. You will work in close collaboration with other scientists and technicians in evaluating vaccine candidates. Also some supervision of the work of technicians is anticipated.

Who we're looking for
For this role we are looking for candidates with a Ph.D in biological/medical sciences with a strong immunology/bacteriology background. You are certified to perform Animal experiments (art. 9 or comparable) and you have experience with developing immunological assays like ELISA, FACS and other assays.
You will actively contribute to the discovery and development of bacterial vaccines therefore we are looking for a flexible, motivated team-player with problem solving capabilities. You maintain accurate written records, and organize your data efficiently (e.g. databases).
