Question

BCG vaccine is used to curb.

Answer 1

Hint: Bacille Calmette-Guérin (BCG) is not commonly used in the United States, although it is often administered to babies and small children in other countries where tuberculosis is prevalent. BCG does not always guard against tuberculosis. This vaccine helps the body develop immunity to tuberculosis, but it does not treat an active infection.

Complete explanation:
The Bacillus Calmette–Guérin vaccine is mainly used to prevent tuberculosis. In tuberculosis-endemic countries, one dose is recommended for safe babies as close to the time of birth as possible. The distinctive raised scar left by BCG immunisation is sometimes used as evidence of prior immunisation. This scar must be distinguished from the scar caused by a smallpox vaccine, which it may resemble.

Note:
BCG is primarily used in tuberculosis vaccination. The BCG vaccine can be given intravenously after birth. BCG also protects against certain non-tuberculosis mycobacteria, such as leprosy. BCG is one of the most successful immunotherapies. Since \[1977\], the BCG vaccine has become the "standard of treatment for patients with bladder cancer. "BCG vaccination should be considered only for children who have a negative TB test and are constantly exposed, and who cannot be isolated from adults who are infected. Are untreated or ineffectively screened for tuberculosis, and the child is unable to receive long-term primary preventive care for tuberculosis infection; or Have tuberculosis caused by strains that are immune to isoniazid and rifampin.

Additional knowledge:
In general, BCG immunisation induces some discomfort and scarring at the injection site. Keloids, which are big, raised scars, are the most serious side effects. The BCG vaccine should be administered intradermally. If administered subcutaneously, it can cause local infection and spread to the regional lymph nodes, resulting in either suppurative (pus-producing) or non-suppurative lymphadenitis.
