In general, there is a profound influence of reducing physical dimensions of particulates and devices on their physico-chemical and biological properties, and their performance. Reduction in the dimensions of hypodermic needle to micron-scale size has gained tremendous interest among researchers. Research efforts and publications investigating the design, development and applications of microneedles have exponentially increased in the recent years. Especially, microneedles have been widely studied and developed for cosmetic and therapeutic applications...

Precise deletion of genes related to virulence can be used as a strategy to produce attenuated bacterial vaccines. Here, we study the deletion of the cyclic-3',5'-adenosine monophosphate (cAMP) receptor protein (Crp) in Aeromonas salmonicida, the aetiologic agent of furunculosis in marine and freshwater fish. The Crp protein is a conserved global regulator, controlling physiology processes, like sugar utilization. Deletion of the crp gene has been utilized in live attenuated vaccines for mammals, birds and warm water fish...

Outbreaks of influenza epidemics are common but influenza vaccination is sub-optimal among the healthcare staff including the medical students. The study aims to assess the rate of vaccine uptake among medical students, its associated barriers and levels of awareness. A cross sectional study was done at a University Hospital in Saudi Arabia on 421 medical students by self administered questionnaire from February to March 2015. The immunization rate of seasonal influenza vaccine was just 20.7% in 2015, while it was 57% for cumulative of previous three-year period...

This commentary introduces a framework within which clinical and research experts in autism spectrum disorder (ASD) can address public instances of evidence denial and promotion of pseudoscience related to ASD. This is a generalized extension of work by a World Health Organization (WHO) group dedicated to reducing the influence of Vocal Vaccine Deniers through educating advocates in how to effectively defuse their arguments. The WHO guidelines were informed by conceptual work on the "denialism" phenomenon, and by studies in psychology, communication, vaccine science, and public health...

BACKGROUND: Influenza virus is responsible for substantial morbidity and mortality. Specific populations are at higher risk for exacerbations from influenza virus, such as patients with chronic obstructive pulmonary disease (COPD). Influenza vaccination coverage among COPD patients is low. Pharmacists can improve influenza vaccination among COPD patients by recognizing factors that influence vaccination and addressing these factors. OBJECTIVES: To (1) determine the recent influenza vaccination coverage among patients with COPD, (2) identify factors that were associated with immunization, and (3) interpret the results based upon Andersen's healthcare utilization model...

Infectious laryngotracheitis virus (ILTV) has a high affinity to replicate in the larynx and trachea causing severe lesions. Apart from the trachea, lack of knowledge exists on the ability of ILTV to replicate in other respiratory associated tissues. The objective of this study was to investigate how tissues that first encounter the virus dictate further sites of viral replication during the lytic stage of infection. Replication patterns of pathogenic strain 63140 and the chicken embryo origin (CEO) vaccine in conjunctiva, Harderian gland, nasal cavity and trachea were evaluated after ocular, oral, intranasal or intratracheal inoculation of specific pathogen free chickens...

BACKGROUND: Typhoid fever remains endemic in low- and middle-income countries. Programmatic use of existing vaccines is limited, but upcoming typhoid conjugate vaccines (TCVs) could warrant wider use. We evaluated the cost-effectiveness of five TCV delivery strategies in three urban areas (Delhi and Kolkata, India and Nairobi, Kenya) and two rural settings (Lwak, Kenya and Dong Thap, Vietnam) with varying incidence. METHODS AND FINDINGS: We evaluated routine infant vaccination with and without catch-up campaigns among older individuals...

Human immunodeficiency virus type 1 (HIV-1) infection is associated with B cell activation and exhaustion, and hypergammaglobulinemia. How these changes influence B cell responses to coinfections such as malaria is poorly understood. To address this, we compared B cell phenotypes and Abs specific for the Plasmodium falciparum vaccine candidate apical membrane Ag-1 (AMA1) in HIV-infected and uninfected adults living in Kenya. Surprisingly, HIV-1 infection was not associated with a difference in serum AMA1-specific Ab levels...

Invasive Meningococcal Disease (IMD) represents a potentially life-threatening condition caused by Neisseria meningitidis. The disease is characterized by a case fatality rate of 5-10% whereas serious clinical sequelae can develop in survivors within 12-24 hours from the first symptoms. However, IMD infection only occurs rarely, in fact, most of the interactions established between N. meningitidis and the host are harmless, and an estimated 10% of the population asymptomatically carries the bacterium in the nasopharynx...

BACKGROUND: The HIV epidemic among men who have sex with men (MSM) continues to expand globally. The addition of an efficacious, prophylactic vaccine to combination prevention offers immense hope, particularly in low- and middle- income countries which bear the greatest global impact. However, in these settings, there is a paucity of vaccine preparedness studies that specifically pertain to MSM. Our study is the first vaccine preparedness study among MSM and female sex workers (FSWs) in Kenya...

PURPOSE: Induction of cell-mediated immune (CMI) responses is crucial for vaccine-mediated protection against difficult vaccine targets, e.g., Chlamydia trachomatis (Ct). Adjuvants are included in subunit vaccines to potentiate immune responses, but many marketed adjuvants stimulate predominantly humoral immune responses. Therefore, there is an unmet medical need for new adjuvants, which potentiate humoral and CMI responses. The purpose was to design an oil-in-water nanoemulsion adjuvant containing a synthetic CMI-inducing mycobacterial monomycoloyl glycerol (MMG) analogue to concomitantly induce humoral and CMI responses...

Smoking remains one of the major causes of morbidity and mortality worldwide. One approach to assisting smoking cessation is via anti-nicotine vaccines, composed of nicotine-like haptens conjugated to a carrier protein plus adjuvant(s). We have previously shown that the carrier, hapten, linker, hapten load, degree of conjugate aggregation, and presence of adducts can each influence the function (nicotine-binding capacity) of the antibody (Ab) induced. Herein, we extend those findings and show that tertiary structure is also critical to the induction of functional immune responses and that this can be influenced by conjugation conditions...

While vaccination is one of the most successful public health interventions, there has always been a parallel movement against vaccines. Apart from scientific factors, the uptake of vaccinations is influenced by historical, political, sociocultural and economic factors. In India, the health system is struggling with logistical weaknesses in taking vaccination to the remotest corners; while on the other hand, some people in places where vaccination is available resist it. Unwillingness to be vaccinated is a growing problem in the developed world...

New vaccine formulations are still highly anticipated in the near-future to face incoming health challenges, such as emergence or reemergence of severe infectious diseases, immunosenescence associated with elderly or the spread of pathogens resistant to antibiotics. In particular, new nanoparticle-based adjuvants are promising for sub-unit vaccines in order to elicit potent and long lasting immune responses with a better control on their safety. In this context, an innovative delivery system of protein antigens has been designed based on the chemical grafting of the antigen onto the shell of Nanostructured Lipid Carriers (NLC)...

The intracellular Toxoplasma gondii parasite replicates within a parasitophorous vacuole (PV). T. gondii secretes proteins that remain soluble in the PV space, are inserted into PV membranes or are exported beyond the PV boundary. In addition to supporting T. gondii growth, these proteins can be processed and presented by MHC I for CD8(+) T-cell recognition. Yet it is unclear whether membrane binding influences the processing pathways employed and if topology of membrane antigens impacts their MHC I presentation...
