When scientists around the world are trying to develop a vaccine to eradicate the coronavirus, it becomes very important to know what is needed for this vaccine. Medical science is very difficult to understand. If it were that simple, every other person would have become a doctor. We have tried to find out from the experts how the corona virus attacks the body. What is the body's response to that? Why is a vaccine needed? How is the vaccine prepared?

How is the vaccine being prepared?

What process has the government decided if time is short?
So let's understand this issue in detail ....
1. What is the body's response to a corona virus attack?
Our body has a wonderful system of nature. When a virus attacks, our body recognizes that an outside virus has become active. An immune cell, called an antigen presenting cell (APC), is the first to encircle the virus. It makes a viral protein, called an antigen. These antigens activate the body's immune system and report that a virus has attacked and it is very important to fight it.
The first killer T cells in the immune system are activated. It activates B cells by identifying antigens. These T and B cells are frontline warriors inside our bodies to fight off virus-like attackers. As they learn that the virus has attacked they increase their numbers.
The disease lasts until the attack and the immune system are activated and the virus takes over. During this time fever, cough, sore throat, difficulty in breathing may occur. If a patient has diabetes, heart disease or other serious illness, the virus increases its number before the immune response is activated. If not treated properly, the patient dies.
This is about the body's own process to fight the virus. Now the question arises that-

2. Why is a vaccine needed to fight the virus?
First of all, what is a vaccine? In fact the vaccine prepares the body to fight a virus before it attacks. Now you may also be wondering if all your family members have been vaccinated, are you afraid of corona? Probably not at all. This action is expected from the vaccine.
The more people who are vaccinated, the more people will be protected from the virus. This will lead to herd immunity, as scientists have said before. Now you say what is this herd immunity? So it is very important for you to know that this is a scientific term, which means that most people's bodies are in a position to fight the virus. This will make it a protective shield for those who have been vaccinated and whose bodies are not ready to fight the virus. This process cannot be a surprise. It happens slowly. That's why vaccines are being awaited to fight the virus.
In fact some countries thought after the epidemic that vaccines were not needed. When most people have corona, their body will develop antibodies to fight it and their immune system will develop. The medical journal The Lancet published a study on such efforts in Spain and found that thousands of people would lose their lives fighting the virus if they did. It was then stated that herd immunity would not occur without the vaccine.Corona Update Live
