New COVID Variants 'Nimbus' and 'Stratus' Cause Sharp Throat Symptoms

A new COVID-19 variant called Nimbus is spreading in the U.S., causing severe sore throats described as 'razor blade' pain, and now accounts for over a third of cases nationwide. While it does not seem to pose a greater public health threat than other variants, it is being closely monitored. Vaccines remain effective against Nimbus, but recent changes in vaccination recommendations have caused confusion about eligibility.
