Passive and active immunity - similarities and differences.
Content
Immunity is a complex mechanism that helps the body survive among millions of infections and viruses. To master this mechanism, the scientists spent more than one decade. But even today there are many not revealed secrets that scientists are working on. In this article we will tell you what the difference between active and passive immunity, as well as how to subordinate them, thereby becoming less prone to infections and diseases.
What is active immunity?
Active immunity is an immunity that appears after a person is ill with a particular disease. This can be a full infection of the disease and victory over it with the help of the resources of the body and drugs, and there may be vaccination, the disputes of which have not stopped for many years.
What is passive immunity?
Passive immunity is an immunity that appears after a ready -made antibody is introduced into the human body. This is not vaccination, although many are mistakenly confused. Passive immunity enters the human body at birth from a mother, with blood transfusion, as well as in the case of artificial administration.
What is the difference between active and passive immunity?
The question arises, what is the difference between active and passive immunity and why do we need all these difficulties with vaccination or diseases, if you can introduce ready -made antibodies and protect ourselves from viruses and infections? Everything is quite simple - active immunity is produced independently by the body, regardless of how it was infected (independently by accident, specially or when entering a small particle of infection - vaccine). After that, B-lymphocytes remember the information for years and when meeting with the same infection (not a mutation), the body will cope as quickly as possible, so that the person himself will not notice.
Passive immunity is a ready-made antibody, which is in the body for a short time and is not remembered by in lymphocytes. Therefore, after the complete removal of antibodies from the body, it becomes completely not protected, as before input.
If you already have a question - so why is a passive immunity, because it seems completely unnecessary. Passive immunity protects the baby from all external risks until the body itself gets stronger. In the case of blood transfusion, this is conditional immunity, which in most cases does not affect human life. But there is an artificial introduction of antibodies into the body, when a person is at risk and there is a chance that infection will lead to death.
In this article, we made out the question of what is the difference between active and passive immunity, but it is worth remembering that not two, but much more varieties, and we can help to strengthen the body and be persistent to most diseases.
Remember that morning exercises, proper seasonal nutrition, fresh vegetables and fruits are the key to health and maintaining immunity at a decent level. This will not create active immunity to you, but in a collision with infections and viruses, it will help to quickly and with minimal losses to overcome the disease!

The article is very interesting ... I have never even thought about it)) Immunity, in general, is very interesting ... Previously, only an abundance of vegetables and fruits was enough for its strengthening. Who knows, maybe the quality of the products has become worse, or the body is used to it now, now for the profiletics of SARS, I just drink a firework from Evalar periodically and that's it) the effect is also good)
Any immunity can be developed if you really want it. You just need to take vitamin D3, C and zinc together together. Plus, it is desirable, of course, to connect minerals. For me, the optimal option is a formula more than polyvitamins, because even doctors often advise (and even those who have a crown, and this means a lot). Everything is in the complex, so the benefits are at a height. I really became less likely to get sick.
For healing and strengthening immunity, physical activity is useful, they should be regular. Any physical exercises are suitable. It is necessary to spend more time in the fresh air. Vitamins are still important. In the fall, before raising the incidence of colds and in winter, I drink the course of the Evalarovskiy complex of zinc, vitamin D3, vitamin C and dihydrocercetin to strengthen immunity in a convenient form of sparkling pills helps to strengthen immunity, restore the body's protective forces.
