A Diagnoses of tuberculosis They significantly increase both in Spain and in the rest of Europe. The case of a football player Lucas Perez He was one of the most presented to court, simply because he is famous, but there are many more. This makes us ask why Vaccine against tuberculosis. We might think that it does not exist, but there is. In fact, it was held in our country until 1980, when it stopped costing.
The tuberculosis vaccine has not disappeared or much less. According to WHO, the vaccine is introduced systematically in newborns from 154 countriesThe field is areas where the frequency of the disease is surprisingly larger than in Spain. It was established here until the situation was controlled. In fact, in 1974 he already stopped introducing into Catalonia. Now this is recommended only for patients with many risks, such as toilets or people who live with patients. Also in the case of some flash. In it Basque country There were times when his administration was recommended in areas with many cases.
Given that cases have been growing recently and that the incidence has increased greatly. Time may come when we again resort to a tuberculosis vaccine. Until then, this is still not recommended for the population as a whole. Let’s see what the reason is, and for this we will first understand how this vaccine works.
Weakened living bacteria and sufficient side effects
In 1921, the Parisian child became the first person to receive a vaccine against tuberculosis. It was a success, so he worked on his major development. For 1930Its administration was widespread around the world.
It was a vaccine based on Weakened living bacteriaThe field, that is, the bacterium itself is introduced Mycobacterium tuberculosis, But previously weakened for the immune system in order to recognize it without the production of the disease. Thus, in the past there was the vast majority of vaccines, although over time many of them were modified to introduce other much more modern technologies.
Instead, the tuberculosis vaccine remains exactly the same. There are others 21 candidate for researchBut no one has yet reached the healthcare system. For all this time it was shown that this only candidate is very effective. Protect significantly in the face of the disease. But this can also lead to sufficient side effects, especially in people with a poorly developed immune system, such as children.
All drugs can produce side effects, so you should always value Benefits/balance of riskThe field if the balance falls to the side of the risk, you should not use this medicine. In the case of a vaccine against tuberculosis, initially the balance clearly chose the advantages, but the time came when the disease was considered sufficiently controlled and that the risks began to appear.
Why is the widespread use of a tuberculosis vaccine not recommended?
According to estimates, 1 out of 4 people in the world have a tuberculosis bacterium in its body. However, alone 10% They experience symptoms. However, the percentage is 50% in the case of children Children under 2 years oldWhich also have a greater likelihood of developing extra -item tuberculosis, in which more organs are affected in addition to the lungs.
Therefore, adults do not need to at the risk of side effects to avoid a disease that rarely causes symptoms. Yes, it may be necessary in children. That is why in countries a high content of diseases are vaccinated for children. However, in Spain the situation was considered Controlled since 1980The field is important that there is a good observation system to identify possible outbreaks and, above all, to find the risk population in which vaccination is indicated. But, in addition, today it is not considered systematically vaccinated.
If cases continue to grow, a vaccine against tuberculosis may be required. This is not so yet. Also, panic should not spread. We have antibiotics And, thanks to them, the disease is perfectly treated.
