Extreme polymorphism in a vaccine antigen and risk of clinical malaria: implications for vaccine development.
Vaccines directed against the blood stages of Plasmodium falciparum malaria are intended to prevent the parasite from invading and replicating within host cells. No blood-stage malaria vaccine has shown clinical efficacy in humans. Most malaria vaccine antigens are parasite surface proteins that have evolved extensive genetic diversity, and this diversity could allow malaria parasites to escape...
متن کاملClinical case definitions and malaria vaccine efficacy.
Reported efficacies from vaccine trials may depend heavily on the clinical case definition used in the trial. The dependence may be particularly striking for diseases such as malaria, in which no single case definition is appropriate. We used logistic regression modeling of the relationship between parasitemia and fever in data sets from Ghanaian children to determine the fraction of fevers att...
متن کاملAdvances and challenges in malaria vaccine development.
Malaria caused by Plasmodium falciparum remains a major public health threat, especially among children and pregnant women in Africa. An effective malaria vaccine would be a valuable tool to reduce the disease burden and could contribute to elimination of malaria in some regions of the world. Current malaria vaccine candidates are directed against human and mosquito stages of the parasite life ...

Citation: Muktikesh Dash. “Malaria Vaccine Development: A Step Towards Reality”. EC Microbiology 2.3 (2015): 294-295. Malaria, a protozoan parasitic disease caused by five species of Plasmodium i.e., P. vivax, P. falciparum, P. malariae, P. ovale and P. knowlesi in humans. Nearly half of the world’s population, an estimated 3.3 billion people in 97 countries and territories are at risk of malar...
متن کاملPrime-boost strategies for malaria vaccine development.
Malaria is an intracellular pathogen, for which an effective vaccine is likely to require induction of cell-mediated immunity. Immunisation approaches that stimulate strong and persistent levels of effector T-cells are being sought by many researchers. DNA vaccines, recombinant protein and viral vectors were amongst the vaccine delivery systems that appeared promising for the generation of cell...
