Introduction: Ebola virus disease is one of the most devastating infectious diseases in the world with up to 90% case fatality observed. There are at least 13 candidate vaccines developed and being tested to prevent the occurrence of the Ebola virus disease. While none of these candidate vaccines has received regulatory approval for use, one candidate vaccine (rVSVΔG-ZEBOV-GP) has been granted access for emergency use. Two other candidate vaccines (GamEvac-Combi and Ad5-EBOV) have been licensed for emergency use in their countries of origin. The objective of this systematic review is to summarise the effects of the Ebola candidate vaccines in humans.
Methods And Analysis: We will search for potentially eligible studies, with no language or date restrictions, in the Cochrane Central Register of Controlled Trials, PubMed, Scopus, the WHO International Clinical Trial Registry Platform, and reference lists of relevant publications. The Cochrane Database of Systematic Reviews (CDSR) and the Database of Abstracts of Reviews of Effect (DARE) will be searched for related reviews. Two review authors will independently screen search records, assess study eligibility, perform data extraction, and assess the risk of bias; and reconcile their findings. We will pool data from similar studies using Mantel-Haenszel's fixed-effect model.
Ethics And Dissemination: This study is exempted from ethical consideration since the data collected are publicly available and at no point will confidential information from human participants be used. We will disseminate our results through publications in peer-reviewed journals and relevant conferences.

Objective: To identify gaps in existing evidence on preconception health interventions to improve the health outcomes of adolescents, young adults, and their offspring.
Study Design: Evidence gap map (EGM) METHODS: Following the Campbell guidelines, we included reviews and interventional studies identified through searches on Medline and other electronic databases from 2010 to July 18th, 2023. Dual screening of titles/abstracts and full texts was conducted on Covidence software, followed by quality assessment and development of 2D-EGM using the EPPI-Reviewer and Mapper software.

Background: Visceral leishmaniasis (VL) is an infectious parasitic disease caused by the species Leishmania (Leishmania) infantum in the Mediterranean Basin, the Middle East, Central Asia, South America, and Central America, and Leishmania (Leishmania) donovani in Asia and Africa. VL represents the most severe and systemic form of the disease and is fatal if left untreated. Vaccines based on chimeric or multiepitope antigens hold significant potential to induce a highly effective and long-lasting immune response against infections by these parasites.

Background: Enteric fever caused by Salmonella enterica serovars Typhi and Paratyphi A in addition to gastroenteritis and invasive disease, predominantly attributable to nontyphoidal Salmonella serovars Typhimurium and Enteritidis, are major causes of death and disability across the globe. A broad-spectrum vaccine that protects against disease caused by typhoidal and nontyphoidal serovars of Salmonella is not available for humans but would prevent a considerable burden of disease worldwide.
Methods: We previously developed a broad-spectrum vaccine for Gram-negative bacteria that is based on the inner core domain of detoxified Escherichia coli O111, Rc (J5) mutant lipooligosaccharide, a highly conserved antigen across Gram-negative bacteria, complexed with an outer membrane protein of group B Neisseria meningitidis.
Generation of a genetically double-attenuated Plasmodium berghei parasite that fully arrests growth during late liver stage development.

Malaria caused by Plasmodium parasites remains a large health burden. One approach to combat this disease involves vaccinating individuals with whole sporozoites that have been genetically modified to arrest their development at a specific stage in the liver by targeted gene deletion, resulting in a genetically attenuated parasite (GAP). Through a comprehensive phenotyping screen, we identified the hscb gene, encoding a putative iron-sulfur protein assembly chaperone, as crucial for liver stage development, making it a suitable candidate gene for GAP generation.

Virus-like particles (VLPs) are formed by viral proteins that, when overexpressed, spontaneously self-assemble into particles that structurally are similar to infectious virus or subviral particles (e.g. the viral capsid).
