Omicron (B.1.1.529): SARS-CoV-2 Variant is highly mutated strain of coronavirus or Covid-19.
Firstly we encountered this virus in 2019 from China. Latest updates if we see then it has spread to every corner of world.
As this virus is moving from one person to another or from one country to other it is changing its structure. This change in structure is nothing but change in protein coat present above virus structure.
When we talk about vaccine it identify the virus protein coat and activates our immunity system.
Check this demo video for more understanding-
If there is change in this coat structure it become difficult for proper activities of vaccine. Earlier delta mutation strain shown 15 protein changes so was dangerous. While talking of omicron it has shown change in 30 protein structure so think how difficult it is globally to tackle this issue.
Omicron birthplace is suggested from china and Africa.
