The Beta Variant is a strain of the virus that causes COVID-19, scientifically known as SARS-CoV-2. It was first identified in South Africa in May 2020 and is also referred to as B.1.351. This variant has mutations in its spike protein, which may affect how the virus enters human cells and could influence vaccine effectiveness. The Beta Variant has been associated with increased transmissibility compared to earlier strains. Public health officials have monitored its spread closely, as it raised concerns about potential resistance to vaccines. Ongoing research aims to understand its impact on public health and vaccination strategies.
