COVID's delta variant has kept some of the most successful mutations found in earlier variants, but also contains new genetic changes that enable it to spread twice as fast. It has a shorter ...

Upon first inspection, the mutations in the highly contagious delta covid variant don’t look that worrisome. For starters, delta has fewer genetic changes than earlier versions of the coronavirus.

Delta also contains mutations in a part of the spike protein called the N-terminal domain, which provides a "supersite" for antibodies to latch onto the virus and prevent it from entering cells, said ...
