Here, we report a dual-route vaccination approach for plague, able to induce a rapid response involving systemic and mucosal immunity, whilst also providing ease of use in those resource-poor settings most vulnerable to disease outbreaks. This novel vaccine (VypVaxDuo) comprises the recombinant F1 and V proteins in free association. VypVaxDuo has been designed for administration via a sub-cutaneous priming dose followed by a single oral booster dose and has been demonstrated to induce early onset immunity 14 days after the primary immunisation; full protective efficacy against live organism challenge was achieved in Balb/c mice exposed to 2 × 104 median lethal doses of Yersinia pestis Co92, by the sub-cutaneous route at 25 days after the oral booster immunisation...

Outbreaks of viral nervous necrosis (VNN) in Asian sea bass (Lates calcarifer) at the larval stages via vertical transmission of nervous necrosis virus (NNV) from asymptomatic broodfish remain as a major deterrent during seed production. A five-year study was conducted to produce NNV-specific-free sea bass broodfish reared in land-based tanks through an annual immunization regimen with the formalin-inactivated NNV. We primarily immunized (intraperitoneal injection) sea bass juveniles (5 g) and monitored the neutralizing antibody (Nab) titers in the sera of these fish at scheduled intervals post-immunization...

INTRODUCTION: The aim was to assess cost-effectiveness of expanding the Swedish HPV-vaccination program to include preadolescent boys, by comparing health-effects and costs of HPV-related disease, with a sex-neutral vaccination program versus only vaccinating girls. METHODS: We used a dynamic compartmental model to simulate the burden of HPV16/18-related disease in Sweden, accounting for indirect effects of vaccination through herd-immunity. The model accounted for sexual behaviour, such as age preferences and men who have sex with men...

Regulated delayed attenuation is a well-studied strategy for retaining the immunogenicity of Salmonella-vectored vaccines. In this study, this strategy was used to optimize two previously constructed recombinant Salmonella enterica serovar Typhimurium vaccines expressing S. Choleraesuis O-polysaccharides (OPS). The novel vaccine strains SLT31 (Δasd ΔrmlB-rfbP ΔPcrp ::T araC PBAD ) and SLT33 (Δasd ΔrfbP ΔpagL::T araC PBAD rfbP ΔPcrp ::T araC PBAD ) were constructed by replacement of the native crp promoter with the arabinose-dependent araC PBAD promoter...

Oral fowl typhoid (FT) vaccine is necessary for improved flock vaccinations and economic growth. This study was undertaken to evaluate the immune responses of birds given oral fowl typhoid vaccine coated with chitosan/alginate microparticles and comparing it with the conventional subcutaneous route of administration. Preliminary studies were done to evaluate the particle size, encapsulation efficiency and agglutination. Sixty day-old chicks were divided into three groups of twenty birds each. This comprised a negative control group NEG 451 (non-vaccinated and non-challenged used as control for cytokine quantification), SC 634 (live 9R vaccine by the injection route) and OCV 567 (live 9R vaccine coated with chitosan/alginate microparticles)...

Globally, rotavirus is a leading cause of childhood diarrhea and related mortality. Although rotavirus vaccination has been introduced in many countries worldwide, there are numerous low- to middle-income countries that have not yet introduced. Pakistan is one of the countries with the highest number of rotavirus deaths in children under five years. Although rotavirus infection is almost universal among children, mortality is often a result of poor nutrition and lack of access to health care and other aspects of poverty...

Current influenza vaccines do not provide effective protection against heterologous influenza viruses. The ability of the novel M2SR influenza vaccine to protect against drifted influenza viruses was evaluated in naïve ferrets and in ferrets with pre-existing immunity to influenza. In naïve ferrets, M2SR provided similar protection against drifted challenge viruses as the comparator vaccine, FluMist®. However, in ferrets with pre-existing immunity, M2SR provided superior protection than FluMist in two model systems...

Rotavirus enteritis is responsible for nearly 200,000 child deaths worldwide in 2015. Globally, many low- and middle-income countries have introduced rotavirus vaccine, resulting in documented reductions in hospitalizations and child mortality. We examined the potential impact and cost-effectiveness of introducing rotavirus vaccination in Lao People's Democratic Republic using an Excel-based spreadsheet model. We estimated mortality risk factors, patterns of care seeking, and vaccination access to predict outcomes for regional, provincial, and socioeconomic subpopulations for one birth cohort through their first five years of life and life course in Disability-Adjusted Life Years estimates...

Ambient temperature filter dried vaccine formulations have been proposed to simultaneously achieve thermostability and offer a ready-to-use immunisation device that combines reconstitution and injection. Vaccine concentration should be uniform at the point of injection, but the uniformity following direct reconstitution of filter-dried vaccines has not been reported. We present here a study of vaccine mixing and release following dissolution of filter-dried model protein and toxoid antigens within a single syringe, filter and needle unit...

Human T-cell leukemia virus type 1 (HTLV-1) has infected as many as 10 million people worldwide. While 90% are asymptomatic, 5% develop severe diseases including adult T-cell leukemia/lymphoka (ATLL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). No vaccine against HTLV-1 exists, and screening programs are not universal. However, patients with chronic HTLV-1 infection have high frequencies of HTLV-1-activated CD8+ T cells, and the two main HLA alleles (A2, A24) are present in 88% of infected individuals...

Identifying the drivers of vaccine adoption decisions under varying levels of perceived disease risk and benefit provides insight into what can limit or enhance vaccination uptake. To address the relationship of perceived benefit relative to temporal and spatial risk, we surveyed 432 pastoralist households in northern Tanzania on vaccination for foot-and-mouth disease (FMD). Unlike human health vaccination decisions where beliefs regarding adverse, personal health effects factor heavily into perceived risk, decisions for animal vaccination focus disproportionately on dynamic risks to animal productivity...
