Immunity to coronaviruses lasts at least a year and could possibly last a lifetime, two new studies have found.

Why it matters: This could offer some peace of mind for lingering concerns about how long protection against COVID-19 will last, the New York Times reports.

  • The studies indicate those who've recovered from COVID-19 and got vaccinated won't need boosters, per the Times.
  • Meanwhile, those who weren't infected but were vaccinated will likely need boosters.

Preliminary Israeli data shows that coronavirus booster shots quickly spike a person's protection against both severe disease and infection, suggesting that the additional shots could help blunt the virus' spread in the U.S. — although it's very unclear how much.

Why it matters: The Biden administration has said that the main rationale for its booster push is to stay ahead of any waning of the vaccines' effectiveness against severe disease. But slowing the spread of the Delta variant would be a welcome bonus.

NIAID director Anthony Fauci said at a press briefing Thursday that the coronavirus variant Mu, which the World Health Organization is now tracking, does not pose an immediate threat to the U.S.

Driving the news: WHO added the Mu strain, first detected in Colombia in January, to its "Variants of Interest" list Monday, warning that early data suggest it may be more resistant to protection from prior infection or vaccination.
