Do you know what is the BCG Full Form? The full form of BCG stands for Bacillus Calmette-Guérin. It is an immunization designed to boost immunity against tuberculosis. Originally developed by French scientists Albert Calmette and Camille Guérin, it was first used in 1921 by Dr Weil-Halle to treat a tuberculosis-infected child. Thereafter, about 320 infants received the BCG vaccine by 1924.
BCG is usually given to children living in TB-affected areas and to individuals at high risk of tuberculosis, such as children living in TB-affected areas, children with one or both parents with TB, or bladder tumors or bladder cancer People with.
How does BCG perform?
- The vaccination works by using a weakened version of Mycobacterium bovis, a bacterium that can cause tuberculosis.
- Once it enters the body, the vaccine signals the immune system to respond to the bacteria without triggering an actual infection.
- The immune system then produces antibodies that can protect against future TB infections, leading to tuberculosis immunity.
What are the things to be kept in mind while applying BCG?
The following things should be kept in mind while applying BCG-
- It is important to note that only a doctor should administer the BCG vaccination, and the vaccine area must be kept clean and dry for approximately 24 hours.
- If the vaccination area starts to seep, a dry dressing like gauze should be applied.
- A sterile alcohol swab may be used to clean the area if necessary, but ointments, antiseptic creams, and band-aids should not be used.
- Certain individuals, including those who have previously had TB, those suffering from HIV, those with a positive result for Mantoux, those with poor immune systems due to underlying illnesses, and pregnant women, may experience complications after receiving the BCG vaccine. Therefore, it is always essential to consult with a doctor before getting vaccinated with BCG.
Who should not get the BCG vaccine?
The following people should not get the BCG vaccine-
- Individuals with a history of tuberculosis
- People who have had a skin reaction after the Mantoux test
- Newborns living in homes with a case of tuberculosis
- Individuals with HIV infection and infants born to HIV-positive mothers
- Individuals with blood cancer and lymphoma
What is the BCG vaccine limitation?
The following are the limitations of the BCG Vaccine:
- Some countries have discontinued the use of the BCG vaccine because of limitations in providing immunity against all forms of tuberculosis.
- Rare cases of immunosuppressive disorders and interference with other vaccines have been reported.
- Despite this, in many cases, the vaccine has been effective in controlling the spread of tuberculosis.
- The BCG vaccine works by introducing inactive or ineffective bacteria into the body, triggering an immune response.
- The immune system produces antibodies against inactive bacteria, which provide protection against potential infection.
- These antibodies remain in the body, providing long-term protection against future exposure to live bacteria.
- The BCG vaccine is usually given in childhood to prevent exposure to tuberculosis and facilitate the development of a strong immune system.
- By simulating the presence of harmful bacteria, the vaccine helps the body develop a shield against potential infection, thereby protecting against future exposure to live bacteria.
