2014 Bacillus Calmette-Guérin (BCG) is a vaccine derived from attenuated strains of Mycobacterium bovis. Mycobacterium bovis BCG-based therapy is considered an effective alternative for bladder carcinoma in situ when exclusive transurethral resection is inadequate. Among the complications associated with therapy, there are few reports in the literature on reactive arthritis. We report the case ...

A preventive vaccine is a substance introduced into the human body that teaches the immune system to detect and destroy a pathogen—which is a particular virus, bacterium or parasite that causes a preventable disease. All vaccines contain some harmless form or part of the pathogen they target. They exert their effects through the adaptive immune response, an arm of the immune system that learns ...

Abstract. A compartmental epidemic model, introduced by Gumel and Moghadas [1], is considered. The model incorporates a nonlinear incidence rate and an imperfect preventive vaccine given to susceptible individuals. A bifurcation analysis is performed by applying the bifurcation method introduced in [2], which is based on the use of the center manifold theory. Conditions ensuring the occurrence ...

Hepatitis B virus infection is one of the most frequent causes of chronic liver disease worldwide. Even though a preventive vaccine is available, the search for a cure for chronically infected patients remains a high priority to reduce the morbidity and mortality from liver cirrhosis and hepatocellular carcinoma. This review summarizes the immune response in acute, self-limited and chronic hepa...

BACKGROUND As HIV infection continues to devastate low-income countries, efforts to search for an effective HIV vaccine are crucial. Therefore, participation in HIV vaccine trials will be useful for the development of a preventive vaccine that will work and thus reduce the global HIV epidemic. OBJECTIVE The objective of this study was to analyse the willingness to volunteer (WTV) in a Phase I...

BACKGROUND We tested the hypothesis that states with higher rates of cancers associated with human papillomavirus (HPV) would have lower HPV vaccine coverage. METHODS We gathered state-level data on HPV-related cancer rates and HPV vaccine initiation coverage for girls and boys, separately, and HPV vaccine follow-through (i.e., receipt of 3 doses among those initiating the series) for girls o...
