BACKGROUND In early clinical studies, the live tuberculosis vaccine Mycobacterium bovis BCG exhibited 80% protective efficacy against pulmonary tuberculosis (TB). Although BCG still exhibits reliable protection against TB meningitis and miliary TB in early childhood it has become less reliable in protecting against pulmonary TB. During decades of in vitro cultivation BCG not only lost some gene...

BACKGROUND Tuberculosis (TB) vaccine trials in South Africa must be approved by the Medicines Control Council (MCC) and by a human research ethics committee (HREC). Delays in regulatory and ethical approval may affect operational and budget planning and clinical development of the product. AIM Our aim was to analyse the time to regulatory and ethical approval for TB vaccine trials conducted b...

Clinical trials of novel tuberculosis (TB) vaccines are expensive, while global resources for TB vaccine development are limited. Therefore, there is a need for robust and predictive preclinical data to support advancement of candidate vaccines into clinical trials. Here, we provide a rationale for using the nonhuman primate as an essential component of these efforts, as well as guidance to the...

Abstract Indonesia’s position as one of the high burden countries for infectious disease, tuberculosis (TB), has caused TB to be a major health problem in Indonesia. As means control number cases, it becomes important government identify factors associated with it. Commonly, multiple linear regression models are used evaluate relationship between identified and cases. Unfortunately, this model ...

Despite considerable research efforts, the treatment of tuberculosis (TB) remains to be a great challenge in the requirement of prolonged therapy with multiple high-dose drugs and associated side effects. As such, the development of an effective vaccine to treat TB may be feasible strategy. The aim of this study was to investigate the possibility of polyethylenimine (PEI) modified nanoparticle ...

Tuberculosis (TB) is a chronic infectious disease, considered as the second leading cause of death worldwide, caused by Mycobacterium tuberculosis. The limited efficacy of the bacillus Calmette-Guérin (BCG) vaccine against pulmonary TB and the emergence of multidrug-resistant TB warrants the need for more efficacious vaccines. Reverse vaccinology uses the entire proteome of a pathogen to select...

To the Editor: BCG (Mycobacte-rium bovis BCG) is a vaccine for preventing childhood tuberculosis (TB), especially military and meningeal TB. Because Taiwan has an annual TB incidence rate of ≈70 cases/100,000 persons, the National Immunization Program has included neonatal BCG vaccination since 1965. The coverage rate has remained at 97% since 2001. According to the Taiwan Tuberculosis Registry...

Tuberculosis (TB) remains a major worldwide health problem. The only vaccine against TB, Mycobacterium bovis Bacille Calmette-Guerin (BCG), has demonstrated relatively low efficacy and does not provide satisfactory protection against the disease. More efficient vaccines and improved therapies are urgently needed to decrease the worldwide spread and burden of TB, and use of a viable, metabolizin...

To help reach the target of tuberculosis (TB) disease elimination by 2050, vaccine development needs to occur now. We estimated the impact and cost-effectiveness of potential TB vaccines in low- and middle-income countries using an age-structured transmission model. New vaccines were assumed to be available in 2024, to prevent active TB in all individuals, to have a 5-y to lifetime duration of ...
