People these days are debating over the efficacy and effects of the various COVID-19 vaccines available out there. Some works on the P1 variant and the others work on the B117 variant. Which one will you go for, this Explainer will help you.

The Pfizer and Moderna vaccines have shown astonishing and essentially equivalent degrees of efficacy, at least in the early stages after vaccination. 

The Covishield vaccine is made from a weakened version of a common cold virus (known as an adenovirus) from chimpanzees. It has been modified to look more like coronavirus although it can't cause illness. 

The Johnson and Johnson one-dose vaccine was shown to be 66% protective against moderate to severe COVID infections overall from 28 days after injection.

Russia's Sputnik V has been deemed to be safe and works in a way similar to the Oxford-AstraZeneca jab which is being made in India as Covishield. Sputnik V gives around 91% protection against COVID-19.

Covaxin is an inactivated vaccine which means that it is made up of killed coronaviruses, making it safe to be injected into the body.
