BCG
BCG stands for Bacillus of Calmette and Guérin vaccine against tuberculosis that is prepared from a strain of the attenuated cow tuberculosis bacillus, Mycobacterium bovis that have lost their virulence by specially culturing in artificial medium for years. However the bacilli retained enough strong antigenicity to become an effective vaccine for the prevention of human tuberculosis.It was prepared for the first time at the Pasteur Institute[?] in Paris in 1906 by Albert Calmette[?] and Camille Guerin[?]. In France the BCG vaccine has been in wide use in humans since 1921. The vaccine proved to be the safest and the most widely used vaccine.
It has an efficacy of between 50 and 80 percent, depending on the natural occurrence of other forms of mycobacteria other than mycobacterium tuberculosis[?] in the environment in which a person lives in.
It isn't currently recommended in developed countries as routine childhood vaccination because the incidence of tuberculosis tends to be much lower there.
Having had a previous BCG vaccination will affect a Mantoux test result.
The BCG vaccination should be given intradermally by a nurse skilled in the technique.

experiment on a small scale, or a large one, either. But I prefer at

remember relating to me at that time an incident concerning the effects
previously, near the town of Matagorde? If I recollect correctly, you
way the charred remains of two wagon-loads of cotton, and three human
slaves, the property of a Mr. Horton, had started a few days before to
treeless prairie, and a few minutes afterward they were surprised by
the resistless billows of an ocean swept by a gale; that there was no

"Yes; I recollect the event."
Now, then, I wish a reply to the simple question: Did the single spark,
No? But what did? You reply, of course, that the spark set the.
