A detailed comparison between Covid-19 Vaccines

A pandemic hit the entire world in 2020, and that's when the gravity of this pandemic left the entire world in sheer distress. Initially, it was more like a mystery, wherein all the scientists and health experts spent sleepless nights finding out the root cause of this virus and the effective treatments. Everything turned upside down in a month, and it was all about "hit and try" while treating the infected patients. Internet was flooded with hoaxes, and quacks were misguiding people. Hospitals worldwide were crammed with throngs of people seeking timely treatment for themselves and their loved ones. There were endless burials and funerals happening all day long, and the atmosphere of grief all around made everything afflictive. 

However, the painful journey didn't last long, as health experts and scientists worldwide worked relentlessly to beat Covid-19. Early this year, some companies introduced the Covid-19 vaccines, which ensured efficacy after making trials. Effective vaccines could be the only panacea to curb this deadly virus, and with leaps and bounds, things started to get better.

The news states that India has vaccinated the highest number of people with the first dose of the Covid-19 vaccine globally.

Getting a jab is the only way to eradicate this virus to some extent, as it reduces the potency and makes it less harmful. You may wonder which vaccine is good for you and your family and look for comparisons. 

This article will give you a clear idea about the difference between Covid-19 vaccine. We have listed down the comparison between Covaxin, Covieshield and Sputnik vaccines that would help you understand better and encourage you to take the jab at the earliest.
