Immunization, Vaccines and Biologicals

Research and development

WHO’s Initiative for Vaccine Research (IVR) facilitates vaccine research and development (R&D) against pathogens with significant disease and economic burden, with a particular focus on low and middle income countries. Our activities span the following areas:

  • facilitation of early stage R&D in disease areas with no available vaccines or sub-optimal vaccines,
  • research to optimize public health impact where existing vaccines are underutilized,
  • research to aid introduction decision-making and post-licensure assessments of risk/benefit
  • research to improve monitoring and evaluation of vaccines in use in immunization programmes.

IVR activities align with the strategic objective 6 of the Global Vaccine Action Plan “Country, regional and global research and development innovations maximize the benefits of immunization”, and with the fifth goal of the Decade of Vaccines “Develop and introduce new and improved vaccines and technologies”.
