Current SARS-CoV-2 Variants of Concern Alpha (B.1.1.7) was the first identified major variant of concern. It was first identified in the United Kingdom in the fall of 2020 and spreads approximately 50% better than the original SARS-CoV-2. There is some evidence that the Alpha variant ...
Since the COVID-19 pandemic first began in December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has continuously evolved with many variants emerging across the world. These variants are categorized as the variant of interest (VOI), variant of concern (VOC), ...

In an effort to predict future evolutionary maneuvers of SARS-CoV-2, a research team led by investigators at Harvard Medical School has identified several likely mutations that would allow the virus to evade immune defenses, including natural immunity ac
From South Africa and Brazil to the UK, new variants of the SARS-CoV-2 virus are regularly being discovered, coinciding with an accelerating international vaccination program. Although this is a normal development, these latest variants are causing alarm. They are fast-spreading, i...
A large study from Ontario confirms that SARS-CoV-2 variants of concern (VOCs), especially the Delta variant, are more virulent than the native strain of the virus, increasing people's risk of hospitalization, admission to the intensive care unit (ICU) and death due to COVID-19. The resea...
