BACKGROUND: Vaccination coverage is the usual metrics to evaluate the immunization programs performance. For the 10-valent pneumococcal conjugate (PCV10) vaccine, measuring the delay of vaccination is also important, particularly as younger children are at increased risk of disease. Routinely collected administrative data was used to assess the timeliness of PCV10 vaccination, and the factors associated with delay to receive the first and second doses, and the completion of the PCV10 3+1 schedule...

Background and aims Childhood vaccinations are an important component of primary prevention. Maternal and Child Health (MCH) clinics in Israel provide routine vaccinations without charge. Several vaccine-preventable-diseases outbreaks (measles, mumps) emerged in Jerusalem in the past decade. We aimed to study attitudes and knowledge on vaccinations among mothers, in communities with low immunization coverage. Methods A qualitative study including focus groups and semi-structured interviews. Results Low immunization coverage was defined below the district's mean (age 2 years, 2013) for measles-mumps-rubella-varicella 1st dose (MMR1\MMRV1) and diphtheria-tetanus-pertussis 4th dose (DTaP4), 96 and 89%, respectively...

Kunitz/bovine pancreatic trypsin inhibitor proteins are abundant in the salivary glands of ticks and perform multiple functions in blood feeding, including inhibiting blood coagulation, regulating host blood supply and disrupting host angiogenesis. In this study, we identified a novel gene designated HA11 (Hyalomma asiaticum 11 kDa protein) from the salivary gland of the tick H. asiaticum. HA11 is encoded by a gene with an open reading frame of 306 bp that is translated into a deduced 101 amino acid 11 kDa protein that shares 27% sequence identity with a Kunitz-like protease inhibitor precursor in Amblyomma variegatum...

Chickens are commonly processed around 35-45days of age in broiler chicken industry hence; diseases that occur at a young age are of paramount economic importance. Early age infection with infectious bursal disease virus (IBDV) results in long-lasting immunosuppression and profound economic losses. To our knowledge, this is the first study comparing the protection efficacy of modified live (MdLV) IBDV and herpesvirus turkey (HVT)-IBDV vaccines against early age variant IBDV (varIBDV) infection in chicks. Experiments were carried out in IBDV maternal antibody (MtAb) positive chicks (n=330), divided into 6 groups (n=50-60/group), namely Group 1 (saline), Group 2 (saline+varIBDV), Group 3 (HVT-IBDV), Group 4 (HVT-IBDV+varIBDV), Group 5 (MdLV) and Group 6 (MdLV+varIBDV)...

The aim of the present study was to improve the immunogenicity of peptide epitope vaccines using novel nanocarriers based on self-assembling materials. Several studies demonstrated that peptide antigens in nanoparticulate forms induce stronger immune response than their soluble forms. However, several issues such as poor loading and risk of inducing T cell anergy due to premature release of antigenic epitopes have challenged the clinical success of such systems. In the present study, we developed two vaccine delivery systems by appending a self-assembling peptide (Ac-AAVVLLLW-COOH) or a thermosensitive polymer poly(N-isopropylacrylamide (pNIPAm) to the N-terminus of different peptide antigens (OVA250-264, HPV-E743-57) to generate self-assembling peptide epitopes (SAPEs)...

Francisella tularensis, a bacterial biothreat agent, has no approved vaccine in the USA. Previously, we showed that incorporating lysates from partially attenuated F. tularensis LVS or fully virulent F. tularensis Schu S4 strains into catanionic surfactant vesicle (V) nanoparticles (LVS-V and Schu S4-V, respectively) protected fully against F. tularensis LVS intraperitoneal (i.p.) challenge in mice. However, we achieved only partial protection against F. tularensis Schu S4 intranasal (i.n.) challenge, even when employing heterologous prime/boost immunization strategies...

The RTS,S/AS01 malaria vaccine has been associated with meningitis and cerebral malaria safety signals. Key characteristics of the meningitis signal include presence, in the 5-17month but not the 6-12week age group, of delayed and variable meningitis onset after vaccination, and multiple etiologies. For both meningitis and cerebral malaria, the 5-17month old age group control arm had abnormally low incidences while other arms in both age groups had meningitis and cerebral malaria incidences similar to background rates...

Longan County is considered a highly endemic area for hepatitis B virus (HBV). The plasma-derived vaccine has been used in newborns in this area since 1987. A cross-sectional survey was conducted to evaluate the long-term effectiveness of this vaccine. In total, 1634 participants born during 1987-1993 and who had received a series of plasma-derived HB vaccinations at ages 0, 1, and 6 months were enrolled. Serological HBV markers were detected and compared with previous survey data. Overall the prevalence of hepatitis B surface antigen (HBsAg) in all participants was 3·79%; 3·47% of subjects who had received the first dose within 24 h were HBsAg positive, and 8·41% of subjects who had received a delayed first dose were also HBsAg positive...

Molecular methods are fundamental tools for the diagnosis of viral infections. While interpretation of results is straightforward for unvaccinated animals, where positivity represents ongoing or past infections, the presence of vaccine virus in the tissues of recently vaccinated animals may mislead diagnosis. In this study, we investigated the interference of RHDV2 vaccination in the results of a RT-qPCR for RHDV2 detection, and possible associations between mean Cq values of five animal groups differing in age, vaccination status and origin (domestic/wild)...

Efforts are currently underway to improve the efficacy of sub-unit malaria vaccines through assessment of new adjuvants, vaccination platforms and antigens. In this study, we further assess the antigen P. falciparum (Pf) upregulated in infective sporozoites 3 (PfUIS3) as a vaccine candidate. PfUIS3 was expressed in the viral vectors chimpanzee adenovirus 63 (ChAd63) and modified vaccinia virus Ankara (MVA) and used to immunize mice in a prime-boost regimen. We previously demonstrated that this regimen could provide partial protection against challenge with chimeric P...

BACKGROUND: The seasonality of influenza is thought to vary according to environmental factors and human behavior. During winter holidays, potential disease-causing contact and travel deviate from typical patterns, and we aim to understand these changes on age-specific and spatial flu transmission. METHODS: We characterized the changes to transmission and epidemic trajectories among children and adults in a spatial context before, during, and after the winter holidays among aggregated physician medical claims in the United States from 2001 to 2009 and among synthetic data simulated from a deterministic, age-specific spatial metapopulation model...

BACKGROUND: Declining incidence and spatial heterogeneity complicated the design of phase 3 Ebola vaccine trials during the tail of the 2013-16 Ebola virus disease (EVD) epidemic in West Africa. Mathematical models can provide forecasts of expected incidence through time and can account for both vaccine efficacy in participants and effectiveness in populations. Determining expected disease incidence was critical to calculating power and determining trial sample size. METHODS: In real-time, we fitted, forecasted, and simulated a proposed phase 3 cluster-randomized vaccine trial for a prime-boost EVD vaccine in three candidate regions in Sierra Leone...

Avian bornaviruses are causative agents of proventricular dilatation disease (PDD), a chronic neurologic and often fatal disorder of psittacines including endangered species. To date no causative therapy or immunoprophylaxis is available. Our previous work has shown that viral vector vaccines can delay the course of homologous bornavirus challenge infections but failed to protect against PDD when persistent infection was not prevented. The goal of this study was to refine our avian bornavirus vaccination and infection model to better represent natural bornavirus infections in order to achieve full protection against a heterologous challenge infection...

Immune control of primary human cytomegalovirus (HCMV) infection appears to depend on the interaction of humoral and T-cell responses. In this review, we have separately explored the 2 arms of the immune response to primary HCMV infection in HCMV-seronegative pregnant women transmitting (T) or not transmitting (NT) the infection to the fetus, with the objective of correlating the immune risk factors associated with vertical HCMV transmission. As for the humoral response, the following findings were documented: (i) in competitive binding assays, antibody titers to different antigenic sites of the gH pentamer complex were significantly lower in T compared with NT women; (ii) in addition, the number of neutralization sites recognized by T was significantly lower compared with NT women; (iii) the plaque formation inhibition assay showed a faster kinetics and a higher titer in NT women...
