Update on call for proposals
In January 2013, the PATH Malaria Vaccine Initiative issued a call for proposals pertaining to transmission-blocking vaccine expression and delivery technologies, including expression of GPI-anchored proteins and particle delivery approaches. We received 22 letters of intent from academic and commercial institutions in Australia, Denmark, India, the Netherlands, Switzerland, the United Kingdom, and the United States and invited 11 groups to submit full proposals. Final selections will be announced this summer.
Malaria research & development funding report
The PATH Malaria Vaccine Initiative (MVI) is working to update the 2011 report on investments in malaria research and development (R&D) in collaboration with Sydney-based Policy Cures
and three other product development partnerships—Foundation for Innovative New Diagnostics, Innovative Vector Control Consortium, and Medicines for Malaria Venture. This updated report will be jointly released with an analysis of the R&D costs and investments required for malaria elimination and eradication, which is being commissioned by the
Malaria Eradication Scientific Alliance (MESA), in collaboration with Policy Cures. MESA and MVI plan to launch the companion reports at the October 2013 Multilateral Initiative on Malaria (MIM) conference in Durban, South Africa.
MVI at MIM
The PATH Malaria Vaccine Initiative is planning a robust presence at the 6th Multilateral Initiative on Malaria (MIM)
Pan-African Malaria Conference, to be held October 6–11, 2013, at the International Convention Centre in Durban, South Africa. As the world’s largest gathering of the malaria community, this scientific conference brings together leading researchers, activists, health workers, public health officials, and policymakers every three to four years at a location within Africa. MIM
was established in 1997 with the mission of strengthening and sustaining the capacity of malaria-endemic countries in Africa through collaborative research and training. Additional information about the conference can be found here.
Portfolio update
The PATH Malaria Vaccine Initiative (MVI) accelerates the development of malaria vaccines by identifying potentially promising malaria vaccine approaches and systematically moving them through the development process. Through strategic and efficient use of resources, MVI maintains a diversity of feasibility studies, translational projects, and at least one advanced
vaccine candidate. Continued support of a project depends on whether the candidate meets a series of clearly defined milestones related to safety, efficacy, and suitability for mass production. Over the last six months, MVI’s portfolio has been updated accordingly.

Publications of interest
Malaria vaccine R&D in the Decade of Vaccines: Breakthroughs, challenges and opportunities
Publication date: April 18, 2013 Journal: Vaccine (supplement)
While progress has been made in reducing malaria mortality with other interventions, vaccines are still urgently needed to further reduce the incidence of clinical disease. The most clinically advanced candidate, RTS,S, is presently undergoing Phase 3 evaluation. At the same time, priorities include the development of more highly efficacious vaccines to prevent clinical disease caused by both Plasmodium falciparum and P. vivax, and the development of vaccines to support elimination efforts by inducing immunity that blocks malaria parasite transmission. This article, published in the Vaccine supplement, provides information on breakthroughs and opportunities in the field of malaria vaccine research and development as well as key challenges being faced.
Modeling the public health impact of malaria vaccines for developers and policymakers
Publication date: July 1, 2013 Journal: BMC Infectious Diseases
Efforts to develop malaria vaccines show promise. Mathematical model-based estimates of the potential demand, the likely public health impact, and cost and financing requirements can be used to inform investment and adoption decisions on the use of malaria vaccines as complements to existing interventions. However, the complexity of such models may make their outputs inaccessible to non-modeling specialists. This paper describes a Malaria Vaccine Model developed to address the specific needs of developers and policymakers to access sophisticated modeling results and test various scenarios in a user-friendly interface. The model's functionality is demonstrated through a hypothetical vaccine.
Qualification of standard membrane-feeding assay with Plasmodium falciparum malaria and potential improvements for future assays
Publication date: March 6, 2013 Journal: PLOS ONE
Vaccines that interrupt malaria transmission are of increasing interest. A robust functional assay to measure this activity would provide a biologically relevant means of evaluating potential vaccine candidates. The authors of this journal article, therefore, aimed to qualify the standard membrane feeding assay (SMFA). SMFA is one of the few biological assays used in preclinical and early clinical development of transmission-blocking vaccines, and this study strongly supports its further development and application.
A chemiluminescent-western blot assay for quantitative detection of Plasmodium falciparum circumsporozoite protein
Publication date: April 30, 2013 Journal: Journal of Immunological Methods
Highly sensitive and reliable assays based on the quantitation of immunologically relevant component(s) in recombinant or whole parasite-based vaccines would facilitate preclinical and clinical phases and the monitoring of malaria vaccine deployment. The authors of this article report a laboratory-grade Western Blot assay for quantitative detection of Plasmodium falciparum circumsporozoite protein in P. falciparum
sporozoite and in recombinant product. To the author’s knowledge, this is the most sensitive immunoassay for the detection of a recombinant or native malarial protein and may have a wider range of applications, including the quantification of immunological component(s) in a vaccine formulation and determination of the antigenic integrity in adjuvanted-vaccine and in stability studies. In addition, this assay can be applied to measure the mosquito infectivity in malaria transmission areas and to determine the effects of intervention measures on malaria transmission.
Inside MVI
The PATH Malaria Vaccine Initiative (MVI) welcomed a number of new staff members this year. More information about these staff members, as well as the entire team, can be found on our website here.
Chris Ockenhouse, MD, PhD
In July, Chris Ockenhouse joined MVI as senior clinical research scientist and medical officer. He provides scientific and clinical guidance to translational project teams in charge of early clinical development, working closely with MVI staff, partners, and academic investigators. He brings a wealth of experience in leading research and development programs focused on discovery, process development, manufacture, and early clinical testing of multiple vaccine candidates against Plasmodium falciparum and P. vivax malaria.
Edward Wu, PhD
In June, Edward Wu joined the team as a project manager in the Research and Development Unit. He works within MVI units and programs to coordinate transmission-blocking vaccine development projects and monitor milestones used to measure program progress toward achieving strategic goals.
Amanda Sanchez
In January, Amanda Sanchez joined MVI as the executive assistant to the MVI director. Amanda has more than ten years of experience providing administrative support to executive-level staff and personnel in both the nonprofit and for-profit sectors.
Maria Gomez, MSc
Also in January, Maria Gomez joined the team as project manager in the Portfolio Management and Translational Projects Unit. She works with external partners and with other units within MVI to coordinate malaria vaccine projects in early clinical testing. She has several years of experience in the development and manufacturing of immunoassays, and she has held numerous process engineering positions as well.
