A malaria vaccine represents an essential complementary tool to curb the stagnation, or even increase, in malaria cases observed over the last decade due to the emergence of resistance to insecticides impregnated on mosquito nets, wars and internal conflicts, as well as global warming. In October 2021, WHO recommended the use of the RTS,S/ASO1 vaccine for children aged 5-17 months in areas of moderate to high transmission. In October 2023, a second vaccine received WHO approval for deployment in the same population, following demonstration of around 70 % efficacy in protecting young children against malaria for one year. Given their partial efficacy, however, these vaccines are not generally recommended for travelers to endemic countries.

Introduction: Malaria remains a significant burden, and a fully protective vaccine against is critical for reducing morbidity and mortality. Antibody responses against the blood-stage antigen Merozoite Surface Protein 2 (MSP2) are associated with protection from malaria, but its extensive polymorphism is a barrier to its development as a vaccine candidate. New tools, such as long-read sequencing and accurate protein structure modelling allow us to study the genetic diversity and immune responses towards antigens from clinical isolates with unprecedented detail.

Background: Molecular methods play an important role in clinical trials assessing anti-malarial drugs and vaccines, as well as in epidemiological studies aimed at detecting Plasmodium species, especially when dealing with large sample sizes. Molecular techniques are more sensitive and generally have a higher throughput compared to the gold standard microscopy. Further optimization can be achieved with automation of nucleic acid isolation, allowing for rapid and precise extraction.

Malaria remains a significant global health challenge, with the deadliest infections caused by . In light of the escalating drug resistance and the limited effectiveness of available vaccines, innovative treatment approaches are urgently needed. This study explores the potential of the probiotic YZ01, isolated from traditionally fermented kindirmo milk, to modify host responses to ANKA infection.

Streptococcus pneumoniae and influenza A virus (IAV) are significant agents of pneumonia cases and severe respiratory infections globally. Secondary bacterial infections, particularly by Streptococcus pneumoniae, are common in IAV-infected individuals, leading to critical outcomes. Despite reducing mortality, pneumococcal vaccines have high production costs and are serotype specific.

Background: In malaria vaccine clinical trials, immune responses after vaccination may be compromised due to immunosuppression caused by concurrent Plasmodium falciparum infection. This has a direct effect on the protective efficacy of the vaccine being evaluated. Therefore, parasite clearance prior to vaccination is being considered.
