The Emerging Strains of SARS-CoV-2 and Current Vaccine Strategies: A Systemic Review

Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) is a single-stranded positive-sense Ribonucleic Acid (RNA) virus that has burst upon the world, causing millions of deaths worldwide. Inadequate public health measures cause the virus to evolve more rapidly, acquiring several mutations Though the virus has a “Proofreading” activity, several lineages and clades have been established based on the characteristic given mutation . The natural mutation most probably occurs due to a chance event called the "Founder effect" that either helps the virus survive or be culled out from the population . Since March 2020, the S:pD614G variant was predominant worldwide.
