Special Issue Information

Dear Colleagues,

Leishmaniasis stands as one of the most neglected diseases worldwide, presenting a significant challenge to control efforts. The escalating resistance to drugs employed in its treatment is an alarming trend. Despite attempts to mitigate the disease's vector, these efforts have largely proven ineffective, leading to its widespread prevalence across numerous countries. At present, there exists no anti-leishmaniasis vaccine for humans, and only one option available for preventing canine leishmaniasis (CanL) in Europe. However, even this option has restricted reach. In Brazil, a country bearing the brunt of visceral leishmaniasis cases in the Americas, all vaccines for CanL have been withdrawn from the market, leaving prevention strategies severely lacking. To combat the spread of the disease, Brazilian authorities have introduced novel measures such as the use of deltamethrin 4%-impregnated collars for dogs. Nonetheless, it is evident that further research is crucial to enhance vector control methods, develop new drugs or treatment regimens for both humans and animals, and advance the development of more effective vaccines.

Leishmaniasis is a neglected tropical disease caused by parasites of the genus Leishmania. As approved human vaccines are not available, treatment and prevention rely heavily on toxic chemotherapeutic agents, which face increasing resistance problems. The development of effective vaccines against human leishmaniasis is of utmost importance for the control of the disease. Strategies that have been considered for this purpose range from whole-killed and attenuated parasites to recombinant proteins and DNA vaccines. The ideal vaccine must be safe and effective, ensuring lasting immunity through a robust IL-12-driven Th1 adaptive immune response. Despite some success and years of effort, human vaccine trials have encountered difficulties in conferring durable protection against Leishmania, a problem that may be attributed to the parasite’s antigenic diversity and the intricate nature of the host’s immune response. The aim of this review is to provide a thorough overview of recent advances in Leishmania vaccine development, ranging from initial trials to recent achievements, such as the ChAd63-KH DNA vaccine, which underscores the potential for effective control of leishmaniasis through continued research in this field.
