The tuberculosis vaccine and the treatments used for it have recently been associated with the Corona virus, and many questions have arisen about how these treatments and vaccines relate to preventing or reducing severe symptoms of the Corona virus.
Dr. Yousry Akil, professor of Chest Diseases at Cairo University, responded in an interview with “Al Arabiya.net” about the relationship of the tuberculosis vaccine to the Corona virus, and there is a relationship between the spread of the virus in countries that do not include the vaccine against tuberculosis in the list of vaccines compared to many countries in Africa and the Middle East. She is eager to provide the vaccine against tuberculosis, among the basic vaccines for children, until now.
Dr. Yousry explained that the tuberculosis vaccine is taken in many African countries and in the Middle East, including Egypt, and is called the “forty injection”, where the child receives it after forty days of birth, and is found in a distinguished place on the north shoulder to be in an internationally recognized location.

He added that the idea of vaccinating for tuberculosis is that it boosts immunity against one of the world’s most dangerous epidemic diseases, which is tuberculosis.
The tuberculosis vaccine is reduced to the fact that a weak microbe is injected, and when it enters the body it stimulates the immune system and, therefore, for 6 weeks the individual has acquired immunity against tuberculosis.
This disease (tuberculosis) has many forms, the most dangerous form is that it is transmitted through the blood to all parts of the body, and this always occurs when a person is exposed to this microbe for the first time in their life, so The benefit of the vaccine is that it works to provide acquired immunity against tuberculosis, so that when exposed to the microbe, the infection occurs in one organ and does not spread to the rest of the body.

Dr. Yousry noted that among the theories that were made about tuberculosis on the African continent, especially that it is a semi-endemic disease in some African countries, and therefore, those who received the BCG vaccine may have less infection by the Corona virus than others who did not receive that vaccination.
The relationship between man and the microbe will always be through the relationship between the immune system and the microbe that entered the body, and in the event that the individual’s immune system is very efficient, it will limit the activity of these microbes and viruses. and you can overcome them. Many of the people infected with the Corona virus show no symptoms, or have simple symptoms, and others deteriorate and have to enter intensive care, depending on the reactions of the immune system of each individual.

This depends on the immunity of the body, as some of the more serious diseases affect a certain ethnic group more than another ethnic group. Some studies have suggested that in the Arab region, the rate of spread of the virus is low, compared to European countries, so they suggested that it has to do with the vaccination against tuberculosis that children receive in our Arab region.
This may be true, since vaccination against tuberculosis has to do with stimulating the lymphatic immune system, which are cells involved in immunity to viruses, such as the Corunna virus, for example, and are called non-specific immunity.
As for specific immunity, it is that for each microbe in a specific antibody, we call it “acquired immunity” after exposure to that microbe, but for the body to do this it needs between two weeks and one month after exposure to the microbe, and there are other non-specific immune reactions that can overcome the microbe.
It may be that the cause of the high incidence of infections in African countries, compared to European countries, due to the many endemic diseases in this region, the immune system is always under pressure, so it is in an active state all time.
At the end of his speech, Dr. Yousry explained that the vaccination against tuberculosis that newborns receive works to stimulate and strengthen immunity against microbes and viruses in general, but so far there is no scientific evidence to demonstrate the link. of this vaccine with the prevention of the Corona virus.
