This study aimed at estimating the paediatric RotaVirus GastroEnteritis (RVGE) burden in children aged up to 5 years, and at evaluating health and economic benefits of a universal infant vaccination with a pentavalent rotavirus vaccine, in France. A decision analytic model was constructed considering a cohort of French children from birth to 5 years old. In the absence of a universal rotavirus immunisation programme, the model predicts that of every new French birth cohort, 336,738 children would present a RVGE case, which would result in 33,386 hospitalisations, 14 deaths and more than 279,000 work days lost for the parents. The management of these RVGE cases would cost 63 million euro to the National Healthcare Payer and would reach up to 117 million euro when all indirect costs were included. The introduction of a universal rotavirus vaccination would avoid 249,400 RVGE cases and consequently about 25,700 hospitalisations, 6000 nosocomial infections, 81,200 emergency visits, 39,900 general practitioner or paediatrician consultations, 11 deaths and 206,700 parental work days lost. RVGE total costs would be reduced by 47 million euro for the National Healthcare Payer and by 88 million euro from the Societal perspective. Therefore, a routine universal rotavirus vaccination programme represents an opportunity to significantly reduce the high paediatric RVGE burden in France.

Broadly neutralizing antibodies (bNAbs) could offer escape-tolerant and lasting protection against viral infections and therefore guide development of broad-spectrum vaccines. The increasing challenge posed by viral evolution and immune evasion intensifies the importance of the discovery of bNAbs and their underlying neutralization mechanism. Here, focusing on the pivotal viral protein VP4 of rotavirus (RV), we identify a potent bNAb, 7H13, exhibiting broad-spectrum neutralization across diverse RV genotypes and demonstrating strong prevention of virus infection in female mice.

Background: Health information systems (HIS) are vital in supporting all aspects of managing health systems, financing, policymaking, and service delivery. A package of priority HIS interventions was piloted in selected woredas across all regions in Ethiopia. This study examined the impact of HIS interventions on maternal and child health (MCH) service utilization.

The coronavirus disease 2019 (COVID-19) pandemic has driven major advances in virus research. The role of glycans in viral infection has been revealed, with research demonstrating that terminal sialic acids are key receptors during viral attachment and infection into host cells. However, there is an urgent demand for universal tools to study the mechanism of sialic acids in viral infections, as well as to develop therapeutic agents against epidemic viruses through the downregulation of terminal sialic acid residues on glycans acting as a glyco-virus checkpoint to accelerate virus clearance.

Article Synopsis
- Despite universal vaccination, Group A rotaviruses (RVA) continue to cause significant childhood diarrhea in the UAE, highlighting the need for genetic monitoring to track prevalent strains and potential vaccine escape mutants.
- The study compared real-time polymerase chain reaction (RT-PCR) and nanopore sequencing for genotyping 33 RVA strains from children, finding that RT-PCR could miss some new strains, whereas nanopore sequencing identified more diverse genotypes.
- The results showed that nanopore sequencing was more effective in revealing emerging strains, with G3P[8] being the most common, thus suggesting its potential role in improving RVA surveillance and guiding preventive strategies.
Potential impact of rotavirus vaccine introduction in India's Universal Immunisation Programme on private sector vaccine utilisation: an interrupted time series analysis.

Article Synopsis
- The study examines the impact of introducing the rotavirus vaccine (RVV) into India's Universal Immunisation Programme (UIP) on private-sector immunization rates.
- After the RVV was introduced, there was a significant decline in private-sector sales across several states, particularly with drops of 37.4% in Rajasthan and 72.2% in Uttar Pradesh-East.
- While some states like Haryana initially saw a rise in private RVV sales, overall trends showed a long-term decrease in private-sector utilization of the vaccine following the UIP introduction.
