A new model of SARS-CoV-2 has emerged in many countries. The latest research has indicated that the virus is mutating rapidly in its state, which may neutralize the currently available vaccines for COVID-19. SARS-CoV-2 is a virus responsible for a disease called COVID-19. A mutation is a change in the genome of an organism or cell of a virus that is more or less permanent and can be transmitted to descendants of a cell or virus. When cells grow, the DNA inside them also replicates to make new copies of cells. Random errors are entered into new DNA during replication generation. Let's know more about the New Model of SARS-CoV-2.
