What does BCG prevent:

Bacillus Calmette-Guérin (BCG, the Chinese name comes from its inventor Ka Shi-Jie) is a vaccine used to prevent tuberculosis. It is made from live, non-toxic bovine tuberculosis bacteria (Mycobacterium bovis). After vaccination, it produces immunity to human tuberculosis by causing a mild infection. More than 90% of recipients will develop ulcers at the vaccination site that last for several weeks to half a year, and eventually heal to form scars, commonly known as "cardiac scars." After several years of propagation on a special artificial culture medium, bovine tuberculosis bacteria lose their pathogenicity to humans, but still maintain a sufficiently high immunogenicity to become a vaccine that can prevent tuberculosis to a certain extent. It is effective in preventing tuberculous meningitis and hematogenously disseminated tuberculosis.

This product was first invented by Leon Calmette and Camile Guerin. It is made by culturing BCG in a comprehensive culture medium, collecting the bacterial film, suspending it in a suitable sterile protective solution, and freeze-drying it. The obtained live bacteria preparation has the functions of producing antibodies, enhancing immunity and inducing the production of gamma-interferon. The live bacterial count of freeze-dried vaccine should be over 1 million per milligram. After dilution for intradermal injection, each 1mL contains 0.5-1 mg.

Through the above introduction, we have a good understanding of what BCG can prevent. So when choosing it, we must have a good understanding of all its aspects.
