Abstract:
Vaccination is one of the most effective public health measures for preventing and managing infectious diseases. Despite intensive efforts from the relatively small medical mycology community, developing effective vaccines against invasive fungal infections remains a scientific challenge. This is predominantly due to large antigenic repertoires, complicated life cycles, and the capacity of fungal pathogens to evade the host immune system. Additionally, antifungal vaccines often need to work for at-risk individuals who are immunodeficient. We anticipate that the success of mRNA vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its exploration for various infectious diseases and cancers will usher a new wave of antifungal vaccine research. Herein, we discuss recent advancements and key scientific areas that need to be explored to actualize the development of effective antifungal mRNA vaccines.
