Determinants of secondary prophylaxis for childhood rheumatic heart disease in Ethiopia: A qualitative study of children and caregivers

Rheumatic heart disease remains a major public health challenge in Ethiopia, particularly among children. Monthly intramuscular benzathine penicillin G is the cornerstone of secondary prophylaxis, yet adherence and delivery are suboptimal. This study explores the lived experiences of children and adolescents with RHD, capturing their direct voices and those of their caregivers to understand determinants of secondary prophylaxis uptake.

The impact of obesity on influenza Vaccine immunogenicity - A systematic review

Influenza vaccines are important for reducing the burden of influenza, particularly for populations at risk of more severe infections. Obesity is associated with increased influenza severity and therefore individuals with obesity are often specifically recommended for annual influenza vaccination. Obesity is also associated with an altered inflammatory profile, which may influence vaccine responses. This systematic review aimed to evaluate the evidence for any association between obesity and influenza vaccine immunogenicity.

Serological Responses to Target Streptococcus pyogenes Vaccine Antigens in Patients With Proven Invasive β-Hemolytic Streptococcal Infections

Rising incidence of invasive β-hemolytic streptococcal (iBHS) infections has prompted consideration of vaccination as a preventative strategy for at-risk populations. The benefits of a vaccine targeting Lancefield group A (Streptococcus pyogenes; Strep A) would increase if cross-species immunity against Lancefield groups C/G (Streptococcus dysgalactiae subspecies equisimilis; SDSE) and B (Streptococcus agalactiae; GBS) was demonstrated. 

Immunogenicity, Reactogenicity, and Safety of a Pentavalent Meningococcal ABCWY Vaccine in Adolescents and Young Adults who had Previously Received a Meningococcal ACWY Vaccine

A MenABCWY vaccine containing 4CMenB and MenACWY-CRM vaccine components has been developed to protect against the 5 meningococcal serogroups that cause most invasive disease cases.

Validity of using a semi-automated screening tool in a systematic review assessing non-specific effects of respiratory vaccines

The abstract screening process of systematic reviews can take thousands of hours by two researchers. We aim to determine the reliability and validity of Research Screener, a semi-automated abstract screening tool within a systematic review on non-specific and broader effects of respiratory vaccines on acute lower respiratory infection hospitalisations and antimicrobial prescribing patterns in young children.

Biomarkers of vaccine safety and efficacy in vulnerable populations: Lessons from the fourth international precision vaccines conference

Vaccination has been a cornerstone of public health, substantially reducing the global burden of infectious diseases, notably evident during the COVID-19 pandemic caused by SARS-CoV-2.

Pharmacokinetics of a three-dose regimen of intramuscular benzathine penicillin G in pregnant women with syphilis

Syphilis remains a global public health concern, particularly in pregnancy due to the risk of congenital syphilis. The WHO recommends benzathine penicillin G (BPG) as the standard treatment in pregnant women, whilst the optimal dosing strategy has not been established, particularly in relation to the impact of gestational age. This study sought to characterize the pharmacokinetics (PK) of a three-dose regimen of intramuscular BPG, given at weekly intervals, in pregnant women with syphilis.

Understanding parental decisions to decline or delay infant RSV immunisation, nirsevimab, in Western Australia in 2024

In 2024, the government of Western Australia introduced 'nirsevimab', a monoclonal antibody offering protection from respiratory syncytial virus (RSV), for eligible infants. This study explores why parents of infants who were eligible to receive nirsevimab opted to decline or delay the immunisation.

Acute rheumatic fever

Acute rheumatic fever is an autoimmune disorder resulting from Group A Streptococcus pharyngitis or impetigo in children and adolescents, which may evolve to rheumatic heart disease (RHD) with persistent cardiac valve damage. RHD causes substantial mortality and morbidity globally, predominantly among socioeconomically disadvantaged populations, with an interplay of social determinants of health and genetic factors determining overall risk.

Characterising the SARS-CoV-2 nucleocapsid (N) protein antibody response

SARS-CoV-2 nucleocapsid (N) protein antibodies can be used to identify the serological response to natural infection in those who have previously received a COVID-19 spike-based vaccine. Anti-N antibody responses can also be induced by inactivated whole SARS-CoV-2 virus vaccines, such as CoronaVac. We aimed to characterise antibody responses to the N protein following COVID-19 and following vaccination with CoronaVac.
