Difficult but Not Impossible: in Search of an Anti-Candida Vaccine

Abstract

Abstract Purpose of Review Pervasive fungal infection among the immunocompromised population, in conjunction with a lack of effective treatment options, has demanded further scrutiny. Millions of people are still dying annually from fungal infections. While existing treatment for these fungal infections exists, it is difficult to administer without adverse effects in the immunocompromised and is slowly becoming obsolete due to varying mutation rates and rising resistance in multiple species. Thus, vaccines may be a viable target for preventing and treating fungal infections and addressing the critical challenge of such infections. Recent Findings Candida albicans, along with other non-albicans Candida species, is among the more virulent class of fungal specimens considered for vaccine development. C. albicans is responsible for a large percentage of invasive fungal infections among immunocompromised and immunocompetent populations and carries a relatively high mortality rate. In the last decade, a recent increase in infective capacity among Candida species has shed light on the lack of adequate fungal vaccine choices. While roadblocks still exist in the development of antifungal vaccines, several novel targets have been examined and proposed as candidates. Summary Success in vaccine development has universal appeal; an anti-Candida vaccine formulation could be modified to work against other fungal infections and thus bolster the antifungal pipeline.
