Corona vaccination from today: Know What is a vaccine, how does it help the body cope with a deadly disease?

The vaccine
 prepares the body's immune system to fight disease. This immune system is called a training course. Vaccines also often damage the natural processes of the immune system. However, usually a person who is vaccinated does not get sick. So let's find out what a vaccine is and how it works.

What is a vaccine?

Our Immune System Naturally protects our body from germs. When a germ attacks the body, the body's immune system sends out special cells to fight it. Sometimes the immune system is not strong enough to kill germs and protect the body from disease. Vaccines are one way to strengthen the immune system.

How does the vaccine work?

A vaccine is a weakened or inactivated form of a germ. Vaccines become the memory of germs in the immune system, so the immune system understands these germs very well and also learns to deal with them. The immune system is immediately activated when the germ is actually infected. The immune system is fully prepared to deal with viruses, germs, or other microorganisms such as pathogens.

Faced a serious illness

Before the advent of the vaccine, people were suffering from deadly diseases like measles, polio, smallpox and diphtheria. Infection with tetanus or bacteria can be fatal. However the vaccine has now overcome this crisis. Smallpox and polio are almost completely gone from the world. Counts of measles and diphtheria are also counted. The transition to tetanus worldwide is also very low.

Vaccines needed for herd immunity

Vaccination also helps protect people. Who cannot be vaccinated, such as a newborn baby, the very sick or the elderly. While enough people in the community are vaccinated against a special infectious disease, the chances of spreading the disease from one person to another are greatly reduced. This type of community protection is what doctors call 'herd immunity'.

The whole process of vaccination is based on the immune system, it is also important to know how our immune system works naturally in the event of a germ attack. Indeed, when bacteria like this virus attack the body, immune cells called lymphocytes produce antibodies. Which are protein molecules. These antibodies protect the body from invading infections, called antigens. According to the Centers for Disease Control and Prevention (CDC), a healthy person can produce millions of antibodies throughout the day. These antibodies fight infection so quickly that humans are often unaware that they have been exposed to an infection.

Y-shaped antibody proteins act on special antigens. When he learns of the germs he has encountered before, he begins to deal with antibodies. He has two jobs. One is to block the antigen so that the germs can be weakened and it can do the least harm to the body. The second signals infection to other immune cells. These other immune cells kill the germs and drive them out of the body. This whole process takes many days when the body is exposed to a new germ.

Identifies antigen Immune

Even after the infection is removed from the body, the immune system retains the germ antigen, also called B cells, in its memory. These cells work to identify and inhibit the antibody to a specific pathogen. In this way, if the germ re-enters the body, the antibody recognizes it and signals the destruction of the immune system before it spreads in the body.

Does the risk of infection a second time decrease

This type of protection against diseases is called immunity. This is the reason that once a child has contracted smallpox, this type of disease does not recur. Immunity is also built in the body through infection. After Ebola, the person does not get Ebola again. There have been several cases of re-infection with the corona virus. However, experts say that the second transition is not as dangerous as the first.

Many deadly diseases around the world have been brought under control with the help of vaccines. So far there are many diseases for which the vaccine has not yet been found. One of which is HIV.
