VCRC has been carrying out Basic & Applied research with the primary objective of finding newer methods and developing strategies for the control of vector borne-diseases. The World Health Organization (WHO) has designated the VCRC as a collaborating Centre for Research and Trainining in Lymphatic Filariasis and Integrated Methods of Vector Control.
