Working of Coronavirus Vaccine

As Coronavirus caused a lot of confusion and fear amongst people, it is natural people were not aware of how the vaccine works. To begin with, a vaccine will work by mimicking an infectious agent.

The agent can be viruses, bacteria or any other microorganisms. They carry the potential of causing disease. When it mimics that, our immune system learns how to respond against it rapidly and efficiently.

As per the traditional methods, vaccines have managed to do this as they introduce a weakened form of an infectious agent. It enables our immune system to basically build its memory.

As a result, our immune system can then identify it quickly and fight against it before it gets the chance to harm us or make us ill. Similarly, some of the coronavirus vaccines have been made like that.

On the other hand, there are other coronavirus vaccines that researchers have developed by making use of new approaches. We refer to them as messenger RNA or mRNA vaccines.

Over here, they do not introduce antigens in our bodies. Instead, mRNA vaccines give the genetic code our body needs to enable our immune system for producing the antigen itself.

For several years, researchers have been studying mRNA vaccine technology. Thus, they do not contain any live virus and also do not interfere with the human DNA.
