Abstract
•Schistosomiasis is still a public health problem in Egypt.•Different levels of morbidity occur during schistosomiasis.•Worrisome fact: praziquantel is the only drug for treatment and mass control.•Egyptian scientists have participated in the battle of vaccination against Schistosoma.
Schistosomiasis has plagued the Egyptian population since the antiquity. The disease is still a public health problem in Egypt, despite the tendency of being overlooked. In the first part of this review, the past and current trends of schistosomiasis in Egypt are reviewed, including history, epidemiology, morbidity, therapy, and control of the disease. Most of these aspects are more or less relevant to other schistosome-endemic regions all over the world. As only one drug is currently available for individual treatment and preventive mass chemotherapy, the quest for complementary measures is urgently warranted. Indeed, one promising approach is the discovery of a vaccine. Herein, we point out the efforts of the Egyptian scientists to develop an efficacious and affordable vaccine against schistosomiasis – a step forward in the battle of elimination of Schistosoma infection. Based on the candidate vaccine antigens, four types of vaccine formulations are discussed: purified antigen vaccines, DNA constructs, attenuated cercariae, and excretory–secretory antigen vaccines. Finally, this review provides insights into this ancient seemingly long-lasting parasitic disease.
