A Rumination on Highly Resistant the SARS-CoV-2 (Omicron) of Mutation, Spread, and Vaccinations to New Challenges

ABSTRACT

When the world is largely focused on battling the Delta spread, On 26 November 2021 WHO announced the new Covid-19 variant, which is highly mutated. That is called Omicron, which is a serious variant of the subject. The current study examines and compares the changes in SARS-CoV-2, Alpha to Omicron. In these mentioned variants, we observed mutations that could have an impact and alter. Its activity with Spike protein, with to negotiated Omicron affected countries situation in review, has focused on the evolution of SARS-CoV2 variants, the vaccine efficacy and rt PCR testing. This review is to focus on special strategies to boom vaccine recognition against Omicron, an important theme of covid-19 situations. These views on overcoming the pandemic's modern-day demanding situations provide strategies to include SARS-CoV-2 globally.
