Right now, many people are hoping for a vaccine to protect against the new coronavirus. While that’s still on the horizon, new research suggests that families who do vaccinate their children may not be following the recommended schedule. Vaccines are given on a schedule for a reason: to protect children from vaccine-preventable disease. Experts designed the schedule so that children get protection when they need it — and the doses are timed so the vaccine itself can have the best effect. When parents don’t follow the schedule, their children may not be protected. And yet, many parents do not follow the sc...

The objective of this research was to generate the evidence on the private sector's contribution to overall immunization coverage for selected pediatric vaccines in India. Using IMS Health's (now IQVIA) vaccine sales audit data and innovative methodological approach we estimated private-sector vaccine share in the total immunization coverage across selected pediatric vaccines in India. Our estimates suggest that private sector remains an important contributor to immunization services in India not only for Universal Immunization Program vaccines (Bacillus Calmette–Guérin [19.23%], HiB pentavalent [11....

Abstract The numerous recent hepatitis A outbreaks emphasize the need for vaccination; despite the effectiveness of the current ones, developments are needed to overcome its high cost plus some immune response limitations. Our study aims to evaluate the use of chitosan and alginate-coated chitosan nanoparticles as an adjuvant/carrier for the hepatitis A vaccine (HAV) against the traditional adjuvant alum. Immune responses towards (HAV-Al) with alum, (HAV-Ch) with chitosan, and (HAV-aCNP) with alginate-coated chitosan nanoparticles, were assessed in mice. HAV-aCNP significantly improved the immunogenicity by increa...

Authors: Martínez Lozano H, Conthe Alonso A, Bañares R Abstract INTRODUCTION: hepatitis A virus (HAV) infection is a common cause of acute hepatitis worldwide. Since the generalization of vaccination, its incidence had markedly declined. Nevertheless, several HAV-outbreaks have been described in the last decade, mainly related to contaminated alimentary products. In recent years, a new pattern of acute HAV infection has been described with changes in the demographic profile of the infected population, which is more common in healthy young men. PATIENTS AND METHODS: a retrospective case series stud...

We present a 13-year old previously healthy Omani with fatal hepatitis A virus infection. This case highlights the critical role of hepatitis A vaccination and argues for consideration of its inclusion in national vaccination programs in order to avert similar devastating consequences of yet another vaccine preventable disease.

Authors: Omara T, Nassazi W, Omute T, Awath A, Laker F, Kalukusu R, Musau B, Nakabuye BV, Kagoya S, Otim G, Adupa E Abstract Uganda is an agrarian country where farming employs more than 60% of the population. Aflatoxins remain a scourge in the country, unprecedentedly reducing the nutritional and economic value of agricultural foods. This review was sought to synthetize the country's major findings in relation to the mycotoxins' etiology, epidemiology, detection, quantification, exposure assessment, control, and reduction in different matrices. Electronic results indicate that aflatoxins in Uganda are produced by ...

This study confirms that hepatitis E is the leading cause of acute jaundice, leads to hospitalizations in all regions in Bangladesh, occurs throughout the year, and is associated with considerable morbidity and mortal ity. Effective control measures should be taken to reduce the risk of HEV infections including improvements in water quality, sanitation and hygiene practices and the introduction of HEV vaccine to high-risk groups.
