The Importance of BCG Vaccination

When you baby is born and newly arrived in the world, it would be almost a sworn duty for you, the parent to make sure the child does not suffer any problem or disease. This is not just concerning the future of the child. It is also about starting right at the beginning and taking some modest steps to save your child from further troubles and problems. One such step is that of adequate vaccination. Vaccines will help to build  a natural immunity against the more damaging and severe diseases and afflictions. One of the important vaccinations is that of the BCG. BCG is the abbreviation for Bacillus Calmette-Guerin. This is a vaccination that will help to protect the new born child from the problem known as tuberculosis.

What is the BCG? Well, in simple terms, it is a vaccine that contains predominantly the strains of the bacterium known as mycobacterium bovis. This bacterium is found to be the principal cause behind the problem of cowpox or even tuberculosis in the cows. The bacterium had been initially found to be quite virulent when tested in human bodies. Later, French bacteriologists Albert Calmette and Camille Guerin developed a better and more advanced system of vaccination for TB. This was in 1908 when a weaker and more diluted version of the same strains of the bacteria was now being used in the BCG vaccines. Initially, disaster had been the result with many new-born babies dying of TB.

The BCG vaccination was soon proved to be quite a strong resistance against the hideous disease of tuberculosis. It has been found that the weak and benign strains of the cowpox and bovine TB bacterium will provide an ample protection against the onset of the real problem. People conducting medical diagnosis and treatment have further verified how the action of the BCG vaccines helps in sufficient protection to any person especially to young children. As of late, people in countries like India and other parts of the world have begun to get a BCG vaccine for their infants and newborn babies. But effective as the BCG is, there are still some reasons why it would not be very effective.

The BCG has so far recorded a good figure in terms of people who have been immunized against TB. However, there have been findings, which have questioned about the efficacy or effectiveness of BCG. Often, the positive results have been drastically low in some countries. In other countries, the results have been quite good. What could be the reason behind such a variance? One is the susceptibility of the people to the virus. If some weak strains of the bacterium have already started their action inside people, the new vaccination will not really work in effect. So, this is why often the BCG vaccination does not produce any good results.

There are some other reasons why the bacterium will not work or will work only under specific circumstances. There could be some genetic mutations in the bacterium. This will cause the bacterium to respond quite variably in different conditions and situations. For this reason, the BCG vaccine will not really work for some cases. In some troubled nations like India and Brazil, the BCG vaccination is important and it has been found to work in most cases due to some circumstances. However, this does not happen in nations like USA or UK. Here, the people would be treated of their TB even without the vaccination of BCG.
