What is vaccine? And how does it work?

A vaccine is a type of medicine that trains the body’s immune system so that it will fight with illness that it has not been in contact with the first. The vaccine is designed to prevent disease rather than treating it when you catch it.

To understand how the vaccine works, first it helps to see how immune power works, as the vaccine can damage your immune system’s natural activity. This short animation states that the vaccine enables the body to make appropriate antibodies to fight a specific disease.

How your child’s immune system struggles with infection:

When your child is infected, its body is based on its immune system to fight the aggressive system. White blood cells are activated and form proteins known as antibodies, which detect infectious agents and make counter-aggressive. At this time, insects may have time to produce some symptoms. In some cases, antibody reaction can be very late to get help and the life of the attack can be severe or life-threatening infections. However, by going on the attack, the immune system and its antibodies can eventually help prevent many infections and help your child recover.

Another important issue to take care of this process is. Even after their job, these antibodies do not disappear. They are always in search of an invaders’ return. If these insects reappear, then it has happened weeks or even years, the antibodies are ready for protection. They can often stop the infection altogether or prevent infection before the first symptoms appear. The reason for this is that if you have confusion or itching in the form of a child, you could never regain it, even if you have come in contact with the same infectious agent.

How does this scenario apply to childhood vaccine?

Antibodies are very specific. If they were made in response to acne virus, for example, they would not work against chickenpox. There are some antibodies that are not so specialized and can save you from similar types of bacteria.

This principle is very similar, even though the details are slightly different. The vaccination depends on the antibody to fight infection. But after vaccination, the antibodies go to work before the first transition develops.

How does a vaccine work?

The live vaccines are made from viruses that are responsible for the disease, or from bacteria. Some vaccines are made up of dead organisms of the organism. These dead animals were killed to protect immunity or their ability to provide protection. In other cases, inactivated poisons made by bacteria or bacteria or pieces of the virus are used. When a vaccine is given, the body’s immune system detects these weak or dead insects or pesticides and responds in the same way when it comes to complete fungus. The vaccine starts making antibodies against the contents. These antibodies remain in the body and if the real infections kill the person, then they are ready to respond.

In one sense, this vaccine tries to bark the body that this attack is going on and the immune system creates weapons that will provide protection when there is a risk of real infection. Occasionally, the vaccine amount is enough to protect one person, but often requires more than one dose.

Some antibodies protect for life, but others need to be encouraged. For example, acne antibody lasts for a lifetime, but antibodies to Titans may fall below a layer which protects you, so booster dosage is necessary. Some viruses, such as flu, can make adequate changes to make existing antibodies ineffective. That is why every year influenza vaccine is needed.

Importance of vaccine for community

According to the Philadelphia Vaccine Education Center Children’s Hospital, vaccines are made from dead or weak antigens. They cannot be infected, but immune system still sees them as enemies and produces antibodies in response. After the danger has passed, many antibodies will collapse, but the immune cells of the disease cells remain in the body. When the body does the antigen again, memory cells are quickly produced by antibodies and delayed before the bomber was knocked down.

Vaccines also work at the community level. According to the CDC, some people do not immunize because they are too small, or because their immune system is very poor. But if they are vaccinated, so the unvaccinated people are protected from the immune system called anything. In other words, they are unlikely to be in contact with the disease, so they probably will not be sick.


In this way, newborns are free from some infections as they get antibodies from their mothers. But in the first month of life, the immune system begins to thrive. For that reason, it is very important to follow the vaccination schedule that your pediatrician will recommend. Also, keep in mind that children do not receive immunity from their mother against some infectious diseases associated with childhood vaccine, including cough and hepatitis.
