Due to the complementarity of their respective activities, the Institute of Hygiene and Epidemiology (IHE) and Pasteur Institute of Brabant (PIB-IPB) merged. This marked the birth of the Scientific Institute of Public Health (WIV-ISP) as we know it until 2018, the year of its merger with the CODA-CERVA. Today, they form the new Belgian health institute Sciensano.
