Abstract
Background: The development of a licensed malaria vaccine has been challenging due to the complex multi-stage life cycle, antigenic variation, and genetic diversity of Plasmodium. Numerous vaccines have been developed for various stages of Plasmodium, including pre-erythrocytic, blood stage, placenta, and transmission-blocking vaccines. However, none of these vaccines are completely effective and have high reactogenicity.Aim: The aim of this review is to examine the challenges and prospects in developing an effective malaria vaccine, with a focus on the development of a multi-stage or multivalent malaria vaccine.Materials and Methods: The authors conducted a review of the literature on malaria vaccine development, focusing on the challenges and prospects of developing an effective malaria vaccine.Results: Efforts are underway to develop a multi-stage or multivalent malaria vaccine (MultiMalVax) that may best target sporozoite development and neutralize merozoites, hepatocytes, and erythrocytes. A thorough understanding of potential vaccine targets and how immunity works is critical to developing a fully effective malaria vaccine.Conclusion: The challenges associated with developing an effective malaria vaccine are significant due to the complex nature of the Plasmodium life cycle. However, the development of a multi-stage or multivalent malaria vaccine offers prospects for overcoming these challenges and developing a fully effective malaria vaccine. A better understanding of potential vaccine targets and how immunity works is crucial in developing an effective vaccine against malaria.
