'Razor blade throat': What to know about COVID's new Nimbus variant

COVID shots no longer recommended by CDC for kids
Health Secretary Robert F. Kennedy Jr. says CDC no longer recommends COVID-19 vaccines for healthy children or pregnant women. The move was announced via a video on X without CDC officials present. A CDC advisory panel was set to vote in June on updated vaccine guidance.
A new COVID-19 variant spreading in some parts of the world has been nicknamed "razor blade throat" because of its painful symptoms.
The variant — NB.1.8.1. or "Nimbus" — has been identified by doctors in the United Kingdom, India and elsewhere, The Associated Press reports.
‘Razor blade throat’ COVID
What we know:
In addition to a painful sore throat, symptoms of the new variant are just like any variant: fever, chills, cough, shortness of breath or loss of taste or smell.
The rise in cases were primarily in the eastern Mediterranean, Southeast Asia and western Pacific regions, but airport screening in the United States detected the new variant in travelers arriving from those regions to destinations in California, Washington state, Virginia and New York.

Experts say so far, people aren’t likely to get sicker from this variant than others, but that could change as it evolves.
What we don't know:
It’s unclear how much the new variant has spread in the U.S.
Are COVID-19 vaccines effective against the new variant?
Big picture view:
The WHO has designated Nimbus as a "variant under monitoring" and considers the public health risk low at the global level. Health experts say current COVID-19 vaccines should still be effective against Nimbus.
