(Latin immunitas – release) – Immunity, resistance of the organism to infectious agents and foreign substances. Immunity is provided by the protective properties of the skin and mucous membranes, cells of the immune system, humoral factors, interferon, etc. Distinguish between congenital and acquired immunities.
The concept of “immunity” was introduced by the Russian scientist II Mechnikov and the French microbiologist L. Pasteur. Initially, immunity was understood as the immunity of the organism to various kinds of infections. However, in the middle of the twentieth century, the English researcher P. Medavr proved that immunity protects the body not only from microbes, but also from any other genetically alien cells (for example, implanted and tumor cells) and parasites.
At the moment, the main function of immunity, according to most scientists, is to maintain the internal constancy of multicellular structures of the body.

The child contained in sterile conditions will be less sick.

So some parents think and try to protect the child from the environment as much as possible – they sterilize children’s things, dishes, feed the child with expressed sterilized milk, do not kiss, do not go out with him to the street, etc. Of course, one should observe basic hygiene measures when at home – a small child, but do not overdo it, as excessive sterility of the environment prevents the normal formation of immunity, which is formed in the womb of the mother. Parents can boldly kiss a child without a mask and take it in their hands, after simply washing their hands with soap (especially after the street and visiting the lavatory), and wash the children’s dishes with enough boiling water. And walking in the fresh air is not harmful to the baby.

Immunity is the root of all diseases.

Wrong. More often, for the development of the disease you need several factors, one of which may be a decrease in immunity. With any disease, many organs and systems suffer, as well as malfunctions in the operation of individual systems can lead to problems in other organs because in the whole human body everything is interconnected.

Infections can and do not be treated – the body’s immune system and itself will do fine.

This opinion is not entirely correct. The immune system copes with many viruses and bacteria, not allowing them to show their pathogenicity, but before large numbers of viruses, bacteria, protozoa or eggs, worms may not survive. In addition, there are pathogens, even small amounts of which are enough to make a person ill (for example, cholera, typhoid fever, dysentery, chicken pox, measles, etc.). If the disease has begun, it must be treated. In some cases, treatment may be an auxiliary, generally tonic. For this purpose, vitamins, adaptogens (ginseng, eleutherococcus), interferon in viral ARI are used. To treat bacterial diseases, antibacterial drugs are used (bacteriophages (special viruses, for the destruction of “bad” bacteria), antibiotics).

Immunocorrection is dangerous, as it can damage the body’s immune system.

It should be remembered that immunocorrection does not replace the work of the immune system, but only helps it in difficult cases, stimulates (normalizes) its work, gives the right direction of activity. After serious illnesses (influenza, dysentery, measles, pneumonia), surgical interventions, radiation exposure, during chronic stress (hard work, long-term illnesses, some chronic infections) as a result of weakening of immunity, serious malfunctions occur in the immune system of the body. In this case, immunocorrection is simply necessary.

General restorative, as well as immune medications easily solve all the problems of the immune system.

Some immune medications (for example, immunosuppressants used to transplant organs to reduce the body’s ability to reject foreign tissues) do not strengthen immunity at all, but serve a completely different purpose. Vitamins, adaptogens and other fortifying agents, as well as hardening, are certainly useful, but sometimes it is not enough to completely eliminate the problems of the immune system. The choice of immune drugs should be handled by a doctor – only in this case you can achieve a good result.

A complete picture of the functioning of the immune system can be obtained from a general blood test.

This opinion is not entirely true. It should be noted that the immune system is very complex and diverse: there is a general immunity (blood, lymph contain a huge number of immune proteins and cells that circulate throughout the body), as well as local tissue immunity in all organs; cellular immunity (lymphocytes, macrophages, etc.) and humoral (immunoglobulins – proteins of the immune response). And even after passing special tests, you can not get complete information about the state of immunity.

Head, stomach, heart aches, various ailments are manifested – immunity decreased.

Wrong opinion. All of the above symptoms are often signs of diseases completely unrelated to the immune system. Signs of decreased immunity will be frequent colds (more than 4 per year in adults and children over 5 years old, more than 6 in younger children), prolonged colds (more than 2 weeks one disease), chronic or recurring infectious diseases, constant temperature 37-38.

Of the diseases that can be treated repeatedly, there can be no immunity.

This is not true. When the microbe gets into the body again, the disease sometimes develops, but the immune system already knows how to fight it, because the disease most often proceeds in mild form.

Vaccinations do not need to be repeated.

It should be remembered that postvaccinal immunity is not as persistent as after the illness, so vaccination must be repeated.

Only immune medications affect the immune system.

Any chemicals have both inhibitory (for example, antibiotics and hormonal drugs), and stimulating (anthelmintic and antifungal drugs, as well as vitamins) influence on immunity. In addition, long-term use of any medicine, even preparations of bifidobacteria, can cause weakening of the protective mechanisms of the body.
