ACH2 represents a continuum in research from basic virology and immunology, through to clinical and social research. The Centre encourages basic scientists, including virology and immunology researchers in HIV and hepatitis fields to translate biomedical discoveries into health care and biotechnology outcomes, and to support clinical research. The Centre has three major activities: a regular expression of interest Funding round for strategic projects; the Immunovirology Research Network (IVRN) Immunovirology Research Network for nationwide research specimen collection and redistribution for strategic research; an Annual Scientific Workshop Workshops to facilitate research collaborations.
