Introduction / objectives The attenuated bacilli Calmette-Guerin (BCG) vaccine is administered in Albania to all newborns at the first day of life to prevent tuberculosis. Although complications are rare after BCG vaccination and the outcome is usually favourable, serious BCG infections can occur. The risks associated with BCG vaccination include local complications, extraregional localized dis...

bacillus calmette guerin (bcg) developed by albert calmette and camille guerin in france between 1908 and 1921 contained a live attenuated strain of mycobacterium bovis and was administered worldwide to prevent tuberculosis. bcg vaccination is also administered at birth to all the newborns in iran. disseminated bcg infection after bcg vaccination is rare. here in, we report 2 new cases of disse...

Mycobacterium bovis is the causative agent of tuberculosis in cattle but also infects other animals, including humans. Previous studies in cattle have demonstrated that the protection induced by BCG is not complete. In order to improve the protection efficacy of BCG, in this study we overexpressed Ag85B in a BCG Pasteur strain, by using an expression system based on the use of an auxotrophic st...

BACKGROUND The BCG vaccine's ability to prevent Mycobacterium tuberculosis infection (MTI) remains highly debated. In Greenland, BCG vaccination was introduced in 1955, but was temporarily discontinued (1991-1996) due to nationwide policy changes. The study aimed to use the transient stop in BCG vaccination to evaluate the effect of vaccination on MTI prevalence and TB incidence. METHODS MTI ...

Background and Objective: BCG vaccination is used in many countries with a high prevalence of TB to prevent childhood tuberculosis meningitis and miliary disease. Local and systemic sideeffects are associated with BCG vaccine. The most critical reaction is disseminated BCG infection which occurs in mostl...

background: different methods have been used for bcg vaccination. alginate microspheres are useful in delivery of vaccines to the gastrointestinal tract by oral route. objective: to compare the immune response following oral microencapsulated and subcutaneous (sc) route administration of bcg vaccine in balb/c mice. methods: alginate microspheres were produced by an internal emulsification metho...

BACKGROUND BCG vaccination confers protection against leprosy, and vaccination among household contacts has been recommended in Brazil. Nevertheless, vaccination of the entire community against leprosy is not advocated as leprosy has low incidence in most populations. Despite that, in Brazil, BCG vaccination is recommended among school children to prevent tuberculosis and this large scale vacci...

tection against leprosy addressed the question of whether or not BCG was effective against leprosy. BCG vaccine trials against leprosy in South America, Africa, and Asia have demonstrated that the BCG vaccine protects against leprosy (). However the degree of protection conferred by BCG is variable between different populations as is its efficacy in the prevention of tuberculosis (). Repeated d...

In this report the methods of the Karonga Prevention Trial, a double-blind leprosy and tuberculosis vaccine trial in Karonga District, Northern Malaŵi, are described in detail. During a total population house-to-house survey, which lasted from November 1985 until August 1989, 121,008 people (57,892 males and 63,116 females) were vaccinated. A further 5835 people refused vaccination and 5757 wer...

BACKGROUND Bacillus Calmette-Guérin (BCG) vaccination may have nonspecific effects, i.e., effects on childhood morbidity and mortality that go beyond its effect on the risk of childhood tuberculosis (TB). Though the available scientific literature is mostly from observational studies, and is fraught with controversy, BCG vaccination at birth may protect infants in high-mortality populations aga...
