All of us know that kids are supposed to be vaccinated. We also know that these vaccines protect kids from certain diseases throughout their lives.

But, what most of the people don’t know is- what actually these Vaccines are? Are vaccines some sort of medicines or anything else!  Or how can they work for a lifetime once vaccinated in the childhood?

A Vaccine actually is a preparation made from the same bacteria or virus that causes the disease.Shocked..!!

Well… it’s not that simple as it sounds. Human body is one quite amazing machine. It has all the attributes to keep a man healthy. It can heal itself, it can cure itself, it can regrow itself, it knows how to breathe etc..etc..  The importance quality in this reference is the quality of self-healing and fighting with diseases causing germs & bacteria. The quick question arises, if so, why do we fall sick..!!!

Answer is human body too has its limits too. It always tries to fight with disease but if its unable to do that due to some reason such as no. of such bacteria, then the human falls sick.

Now, coming back to vaccines, these vaccines are made in so much dilute form (i.e. their strength is very low), such that upon insertion into human body, these vaccines don’t cause the disease in the human. What they cause at max is fever or irritation. That is why babies develop fever post vaccination. What actually is happening in the kid’s body is that, its fighting the inserted bacteria. In a couple of days, it overpowers the bacteria and kids or human does not fall sick permanently.

Now, when the vaccine is injected in the body, then the human body makes antibodies and antigens to fight the bacteria present in the vaccine (that’s what our immune system does). Eventually, body learns how to destroy this bacteria. This gives the body the ability to fight that disease. If in future disease or virus comes in contact with that person, the disease/ virus does not have any negative effects on the body as it has developed the mechanism to fight that bacteria or virus. And that is how, vaccine works.

Question arises why vaccination is done only kids-  Answer lies in the body capabilities of a baby and  grown up. Body is very adaptive in a baby. It immediately develops antigens and antibodies to counter the bacteria. While, in a grown up person such ability is not there. So, vaccination does not work.

Vaccines are made from the bacteria- Is vaccination safe!

Yes, these are totally safe. Thousands of test are performed to qualify these vaccines for human use. They are perfectly safe. Every child must be vaccinated.

This actually is a very important questions. Purposefully, it is explained in much details. It tells us how human body immune system works? When do we fall sick? Then, it does cover vaccines too.

It’s our duty to ensure that all the kids below 5 years of age are vaccinated.
