Background: Among occupational hazards in healthcare settings, latent tuberculosis infection (LTBI) ranks as a major concern, particularly threatening healthcare workers (HCWs) in nations grappling with intermediate to high tuberculosis (TB) rates. Our study was conducted in Morocco, a country characterized by widespread Bacillus Calmette-Guérin (BCG) vaccination and a moderate TB burden of 93 cases per 100,000 inhabitants in 2022. We examined both the prevalence of LTBI among Moroccan HCWs and its various risk factors.

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.

BCG remains the only licensed vaccine for tuberculosis (TB), but its efficacy wanes over time. Subunit vaccines, aim to improve BCG immunity and protection, by inducing responses to a few mycobacterial antigens delivered with a specific platform. Since the platform shapes the immune response induced, selecting the right platform has been challenging due to the lack of immune correlates of protection.

Tuberculosis (TB) remains a significant global health issue due to the limited efficacy of the Bacillus Calmette-Guérin (BCG) vaccine, highlighting the need for the development of an improved TB vaccine. In this study, we created a novel TB subunit vaccine consisting of TB-secreted chorismate mutase (TBCM) (Rv1885c) and a hepatitis B virus (HBV)-derived peptide (Poly6), which elicits Type I interferon responses, both with and without an alum adjuvant. We evaluated the immunogenicity, protective efficacy, and therapeutic efficacy of this vaccine candidate in an in vivo mouse model.

Tuberculosis (TB) in childhood presents a substantial global burden with nearly two million episodes of disease in children and adolescents annually. The majority of children who die from TB never receive appropriate treatment. Advancements in childhood TB treatments have been slow and there are many challenges with TB treatment in children.
