|March 15, 2014
Summary
New tuberculosis (TB) vaccines are in clinical trials, but challenges remain. The bacille Calmette-Guérin (BCG) vaccine is limited, and new candidates need careful selection for global TB control.
Area of Science:
- Immunology
- Vaccinology
- Infectious Diseases
Background:
- Tuberculosis (TB) is a significant global health challenge requiring improved interventions.
- The current bacille Calmette-Guérin (BCG) vaccine offers limited protection against pulmonary TB.
Purpose of the Study:
- To review novel tuberculosis vaccine candidates in clinical development.
- To assess the progress and challenges in TB vaccine research.
Main Methods:
- Review of ongoing clinical trials for TB vaccine candidates.
- Analysis of different vaccine platforms, including subunit, viral vector, and recombinant BCG.
Main Results:
- Several novel TB vaccine candidates are in various stages of clinical trials, including phase IIb.
- Subunit booster vaccines and replacement vaccines for BCG are under investigation.
- The MVA85A vaccine candidate failed to demonstrate efficacy in a phase IIb trial.
Conclusions:
- The development of effective TB vaccines faces financial, regulatory, and infrastructural hurdles.
- A global strategy is needed to address these challenges.
- Prioritizing promising vaccine candidates is crucial for future TB control efforts.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
