Just like the flu, every virus mutates in its life cycle. This mutation doesn’t seem to be more aggressive, and a new vaccine could protect against the original strain and close mutations.

Key Points:

  • The new coronavirus is mutating, but very slowly.
  • Mutations aren’t making it deadlier or more contagious.
  • Vaccines should still be effective.
  • Immunity is currently still unknown.

With RNA viruses, like the coronavirus (SARS-CoV-2) that causes COVID-19, they’re happening constantly — basically every time it replicates. But not all mutations stick, and not all the ones that stick are bad. In fact, mutations are actually necessary for tracking and containing COVID-19. Here’s how viruses mutate and why you shouldn’t be worried when you hear about them.
