Vaccines are synthetic protection that we humans made for ourselves to protect ourselves from existing diseases and infections. It is a chemical substance that helps to boost your immune system and gives protection from one or several diseases.  

Many types of infections and diseases exist in the world that can be life-threatening or even lead to death. Our immune system is not strong enough to fight off all the existing diseases and these diseases can easily harm you and the people near you. To eradicate this problem, vaccines were introduced to fight off these diseases. 

Some vaccine doses are given one time while some need to be given twice (or more) to increase the long-time effect of the vaccines. Although these vaccines are clinically tested and government tested and certified, it is exceedingly rare if someone develops some serious health condition. 

How do vaccines work?  

As you know, our immune system is the defense system that protects us from deadly viruses, infections, and diseases. We are exposed to pathogens (disease-causing organisms) that affect our bodies. The immune system defends our body from these pathogens. If pathogens infect us, the immune system gets triggered, fights off the pathogens, and destroys them before they harm us.  

Our immune system creates antibodies to fight off these pathogens. The formation of antibodies comes from a subpart of pathogens (called an antigen) and by large proteins structure in the body. These antibodies are the soldiers that fight against pathogens and destroy them to protect your body.  

When you are exposed to an antigen, the body takes time to adapt and creates antibodies specific to that antigen. Once antibodies are created, they can protect you from future exposure. 

But some pathogens are stronger, and our immune system is not able to create antibodies (to their antigens) which results in us developing symptoms of that disease. These pathogens start destroying cells of our immune system to take control of the body. Here, vaccines save us. 

Vaccines contain inactive or weak particles of the antigen (of that pathogen) which can help our immune system to create antibodies to fight against that specific pathogen to protect our body. That’s why vaccines are effective against disease because they provide antigen that helps the body to create antibodies to fight against the disease.  

Some vaccines need to be given in multiple doses weeks or months apart because of the production of long-lasting antibodies and the development of memory cells for that antigen. So, in the future, if our body is exposed to those pathogens, it produces antibodies with the help of memory cells to fight the disease and win.  

How can vaccines protect you?  

Vaccines are chemical substances that protect us from one or a certain number of diseases. Vaccines contain inactive or weakened particles of pathogens that cannot harm us instead help our body to use them as an antigen to create antibodies to fight against the disease and destroy them.  

Some vaccines are given in more than one dose to make our memory cells understand the pattern of the antigen so that in the future they can produce antibodies to fight the disease. It also boosts our overall immunity to fight similar types of diseases.  

And if you are vaccinated, people near you are also protected because the transfer/transmission of diseases will get decreased. If more people in the community get vaccinated, the spread of the disease will decrease and, in the future, the disease will cease to exist. If a whole community is vaccinated is known as herd immunity.  

That’s how vaccines protect you and the people near you.

Vaccination works as a shield that protects you from one or a certain number of diseases. These vaccines have gone through many lab tests and government tests before coming to use. You might develop minor side effects (like soreness or mild fever) which can easily go away in several days or you can take medicine to improve but not any major conditions.  

So, you can easily protect yourself and the people around you by taking vaccines.
