"Understanding JN.1: Symptoms, Vaccines, and Public Risk of the New COVID Variant"

The JN.1 variant, a descendant of the omicron variant, is on the rise in the U.S. It is either more contagious or better at evading the immune system, but there is no evidence that it causes more severe disease. Symptoms are likely to be similar to other recent variants. Current COVID-19 vaccines and treatments appear to be effective against JN.1. To protect against the variant, experts recommend getting vaccinated, wearing masks in crowded indoor areas, and practicing social distancing.
