Corona virus has almost devastated the world. The rate at which people have been infected with the virus has not been able to cope in any way.So many people think that this vaccine introduces antibodies to the body which fight against the virus, while many people think that it may be a medicine that protects the body from the damage caused by the corona virus. But do you know what the scientific explanation is for the virus being injected into the body through the vaccine, or let's see how true it is?

Every country has an army. And the main reason for having an army is that they will protect the country from the enemy forces.The main responsibility of the army is to protect the sovereignty of the country by fighting with them when foreign invaders attack.

Our body also has a defense system where there are armies, there are different ranks of army and they are constantly protecting our body from external enemy attacks without our knowledge, this defense system is called Immune system. Vaccine helps to strengthen that immune system.There is blood flow everywhere inside our body. Blood flows through veins, sub-veins, arteries etc. So one of the components of blood is called white blood cell. One of the cells of white blood cell is called lymphocyte. These include B cells, T cells, Memory cells, some of the cells that work together as an army in our body.

When a harmful bacterium, virus or pathogen enters the body from outside and passes through the nose, ears, mouth, eyes, genitals, etc. it first tries to identify B cells and T cells whether the "foreign particle" or foreign particle is harmful or beneficial to the body. It's a lot like a border checkpoint.

If beneficial, it is released, but if harmful, B cell makes antibodies against the particle, which binds to the particle, inactivates the particle, or digests or kills it through a process called phagocytosis. A cell called the memory cell stores the properties of that bifurcated particle as a memory so that when that particle re-enters later, it does not have to waste time checking and sorting, it can be attacked directly.

For example, once a person has smallpox, it will not happen again. The reason is that the memory cells of the white blood cells in the body recognize the smallpox virus, so that as soon as the smallpox virus enters the body, other lymphocytes attack and kill that bacterium. But the germs of all diseases are not common features, there are some variations, which are beyond the ability of memory cells to recognize. In their case the normal defense system in the body fails. What will happen then?

In this case, the vaccine or the vaccine 2 given from outside. What is the use of vaccine?

As I said before, many people think that the vaccine may be the injection of antibodies into the body or the vaccine is something that produces antibodies in the body. But that is not the case.

In fact, the vaccine is used to inject the dead part of the germ of a specific disease. It may be the nucleus, spike or any part of the germ but it is dead. So what is the reason for injecting this dead part? This is because, as mentioned earlier, B cells and T cells work to detect pathogens.

But in the case of diverse viruses, it takes longer to identify them, during which the virus reproduces and becomes stronger, causing the B-cell and T-cell armies to be defeated in battle. Now the cells begin to work to identify the dead part that has been inserted into the body through the vaccine. After identifying the bacterium as harmful, they do two things, firstly, by storing the memory in the memory cell that the particle is harmful, and secondly, by making antibodies against it.

Corona epidemic is currently raging around the world. It is a contagious disease called corona virus. Corona vaccine has been invented. Many wonder how this works!

When a person is vaccinated against the corona virus, it means that a dead part of the corona virus has been injected. The B cell and T cell will attack the dead part and identify it as harmful, as soon as it is identified, that memory will be stored in the memory cell and antibodies against this virus will start to form. But the dead part of the virus will not be able to do any harm to the body, and no antibody will be needed to destroy it, they will be stored in the body. Antibodies will kill the virus as soon as a corona virus enters. In addition, as soon as the virus enters, it will identify the virus as harmful and start producing a lot of antibodies, because they are already familiar with the enemy.

Now what if the virus enters a body that has not been vaccinated with coronavirus?

The B cell will then try to detect the T cell virus, and in the time it takes to do so, the corona virus will reproduce in the body and form large groups that will break down the body's immune system and take over the body and the person will be infected. Simply put, the vaccine identifies the body with the enemy in advance so that if the enemy attacks, without wasting time preparing for battle, the enemy can be defeated immediately by direct counter-attack.

Thank you for this tremendous update. My immune system is gallantly ready to fight back the corona virus😹😹.

Welcome.May god bless you.

Today I saw a news debate on Omicron virus. Doctors said that the current vaccine can protect people from six to eight months. However in some cases antibodies are found even after eight months. And that's why in most countries booster is being recommended. But I don't know how long booster will protect people.

It must be taken if it is beneficial.may god bless us.
