Scientists from Harvard University named the blood group with the strongest immunity. They conducted a study showing that the blood type affects the body's ability to produce interferon in the event of a viral infection.
Interferons are proteins that secrete body cells when in it gets a virus, bacteria and low molecular weight organic compounds.
Studies have shown that people with the first and third blood groups have an average body defense. Scientists said that in this case, the human body will be protected by 80 and 91%, respectively. That is, these people will be able to avoid severe consequences from viral infections and other diseases where a good reaction of the immune system is needed.
It turned out that the owners of the second blood group have the lowest result. Such people will not be able to avoid the serious consequences of contracting viral infections. In this case, the human body will be protected by only 40%. In addition, such people are susceptible to various diseases.
According to scientists, people with the fourth blood group have the strongest immunity. In 92% of volunteers, it was found that interferon is produced in the required amount to protect the body. And sometimes even in excess. A person with this blood type is most likely to avoid any consequences of diseases.
