Summary: This review explores the strategies for developing and using auxotrophic BCG strains, which can serve as a model for studying M. tuberculosis and potentially provide a stable and effective alternative to BCG, as well as a vector for recombinant live vaccines.

Summary: The BCG vaccine, initially designed for cattle, has saved many lives since its first administration to a newborn in Paris in 1921. While providing strong protection against miliary and meningeal tuberculosis in children, it is less effective in preventing pulmonary tuberculosis in adults. It has also shown non-specific benefits against non-tuberculous infections and immunotherapeutic benefits in certain cancers.

Summary: The study found that BCG vaccine protection against Mycobacterium tuberculosis infection decreased with increasing exposure to the pathogen in the Gambia, with the strongest protection observed in the lowest exposure tertile. These findings are consistent with previous results from Indonesia.

Summary: Optimizing the boosting schedule of subunit vaccines can enhance long-term protection against tuberculosis. Boosting with MH twice or immunizing with EC thrice after BCG priming can improve immune memory and increase protection against bacteria.

Summary: The study found that BCG vaccination can reduce the number and size of tuberculosis lesions, decrease necrosis, and increase fibrosis in low-grade lesions. Vaccination has minimal impact on mineralization and density of multinucleated giant cells.

Summary: This study demonstrates that enhancing the protective efficacy of M. bovis BCG in mice and guinea pig infection models by inhibiting Akt inhibitor MK-2206 promotes FOXO3 activation and BCG-induced immune responses.

Summary: Vaccination of badgers with Mycobacterium bovis Bacille Calmette-Guerin (BCG) has been shown to protect badgers against tuberculosis in experimental trials. The study results suggest that BCG vaccination could indirectly protect unvaccinated badgers, leading to a high level of population immunity against tuberculosis. This indicates that BCG vaccination could be an effective method for reducing tuberculosis incidence in badger populations.

Summary: The rBCG-LTAK63 vaccine induces a long-term polyfunctional Th1/Th17 response and an increased presence of memory T cells, leading to improved protection against Mycobacterium tuberculosis (Mtb) in mice. This enhanced immune response may contribute to the long-term protection provided by the vaccine.

Summary: Tuberculosis is a major infectious disease with high mortality rates in certain regions, and the existing BCG vaccine is ineffective for long-term protection. The exact immune factors crucial for preventing Mycobacterium tuberculosis infection and progression of the disease are still unknown after decades of research. Developing a new vaccine to replace BCG and provide better protection is a challenging task due to the intracellular lifestyle of the pathogen and its manipulation of host immunity. This review discusses promising strategies and possibilities for creating a new vaccine, including supplementing mycobacterial strains with immunodominant antigens and genetic engineering to alter the bacterium-host cell interaction.

Summary: This study reviewed the BCG vaccination records from 2019 to 2021 in Grampian, Scotland and found a high uptake rate, surpassing the key performance indicator target in Scotland and showing improvement compared to earlier rates. Strengthening electronic systems and raising awareness can further enhance BCG vaccination uptake.

Summary: A new tuberculosis vaccine PEPf was developed, which can reduce lung bacterial load and improve protection. Combining PEPf with the Advax4 adjuvant and using a prime-boost strategy as a subunit vaccine significantly enhances protection.

Summary: This study aimed to investigate the effects of BCG vaccination and M. tuberculosis infection on the gut and lung microbiota in mice. The results showed that both vaccination and infection had an impact on the relative abundance and diversity of microbiota in the lung and gut. However, the lung was more affected than the gut. The study also revealed that the host's local response to infection affected the overall microbial flora, while the immune response to vaccination mainly influenced the gut microbiota. This study highlights the importance of gut and lung microbiota in the immunopathogenesis of tuberculosis and suggests that manipulating these microbial communities could improve vaccine response and develop treatment adjuvants.

Summary: The limitations of BCG vaccine for tuberculosis necessitate the development of a more effective and safe alternative. The evaluation of BEAP in infant rhesus macaques demonstrated its non-toxicity and ability to activate the immune system to eliminate infected macrophages, suggesting its safety and efficacy as a potential vaccine option.
