Coronavirus Variant

Advisers ultimately said sticking with JN.1 rather than its offshoots promises to offer a better chance at cross-protection. The FDA will decide the final recipe soon.

The CDC estimates that up to 86% of new COVID-19 cases stem from the latest mutation. The virus continues to evolve so rapidly that "our immune systems have not been able to keep up," an expert says.

Health officials predict that the variant may be more transmissible or is better at evading immune systems. However, there's no sign so far that JN.1 causes more severe illness than other variants.

Health experts are encouraging people to get the booster to help prevent another holiday surge, but many people have not answered the call.

Step aside, BA.5. The new variants BQ.1 and BQ.1.1, appear to be among the most adept yet at evading immunity from previous infection and vaccination.

As the country faces a rise in infections driven by the BA.5 subvariant, about 70% of people 50 and older who got a first booster shot haven't received the recommended second one, according to the CDC.

University of Miami researchers have been tracking SARS-CoV-2 variants through genomic sequencing. The effort's leader says: “We are now mirroring the national trends."

Treatments are only available for patients at high risk for developing severe COVID-19. Select pharmacies and health facilities have supplies.

Another version of omicron is spreading in Asia and parts of Europe. And it shows signs that it could be slightly more contagious than omicron. Where did this new variant come from?

In a letter sent to HHS Secretary Xavier Becerra, Dr. Joseph Ladapo wrote that federal agencies should not be controlling COVID options. He asked that Florida be able to pursue unlimited acquisition of any treatment.
