This pandemic has taught us many things, and right now in India as well as in World every other person is talking about vaccines, what are vaccines, how much time is require for development of vaccine including all trails , and how do they work ?

So, for now I would like to answer one of most frequently asked question HOW VACCINE WORKS ? well, for understanding the working of vaccine we must know what is vaccine ?

A vaccine is part of a germ that is exposed to your immune system in a safe way so that it can learn how to fight off that harmful pathogen and protect your body from it in the future. Basically it provides us immunity.

Well let’s see what exactly happens when you get vaccinated

When you get a vaccine, your immune system responds to the vaccine just like real germs.

i. The germs contained in the vaccine are identified as foreign.

ii. The vaccine produces and reacts with antibodies similar to real germs.

iii. Remembering how to destroy germs. If you come in contact with pathogenic germs at any time in the future, your immune system can quickly destroy it before it has a chance to make you sick. This is how you get immunity from vaccines


A vaccine works by training the immune system to detect and protect against viruses or bacteria. To do this, certain molecules from the pathogen must enter the body to boost the immune system. These molecules are called antigens and are found in all viruses and bacteria. If a bacterium or virus reappears, the immune system immediately recognizes the antigen and attacks the disease well before the pathogen spreads.

Vaccines don’t just work on an individual level, they protect entire populations. Once enough people are immunized, opportunities for an outbreak of disease become so low even people who aren’t immunized benefit. Essentially, a bacteria or virus simply won’t have enough eligible hosts to establish a foothold and will eventually die out entirely. This phenomenon is called “herd immunityor “community immunity,” and it has allowed once-devastating diseases to be eliminated entirely, without needing to vaccinate every individual.

So, for now I have only one request that is ”PLEASE GET VACCINATED”, it’s totally safe.
