Alpha—the variant formerly known as B.1.1.7 and first identified in the UK—swept the country at the start of the year. It’s estimated to be around 50 percent more transmissible than the ...

The SARS-CoV-2 Alpha (B.1.1.7) variant mutated to evade our ‘innate immune system’, helping establish it as the world’s first ‘Variant of Concern’, finds a new study led by researchers ...

Somehow, the immune system’s most important alarm bells were barely ringing in the presence of the Alpha variant. “It’s making itself more invisible,” Dr. Towers said. Image.

The Alpha variant of SARS-CoV-2 - the first "variant of concern" - evolved mutations that allowed it to more efficiently suppress the immune system's early response to infection, according to a ...

New SARS-CoV-2 variants are spreading rapidly, and there are fears that current COVID-19 vaccines won't protect against them. The latest in a series of structural studies of the SARS-CoV-2 ...

The rapid spread of the Alpha variant of COVID-19 in the UK resulted from biological changes in the virus and was enhanced by large numbers of infected people 'exporting' the variant around the ...

Alpha made up 98 percent of all COVID-19 cases in the U.K. at that variant’s peak in March; Delta has since taken over, accounting for almost all new cases. It’s too early to say whether the U ...

In December, British researchers discovered that a new variant was sweeping through their country. When it arrived in other countries, the variant, now known as Alpha, tended to become more common ...
