Understanding Covid Variant JN.1: Implications for Reinfection and Vaccines
The Covid variant JN.1, which accounts for the majority of U.S. cases, raises questions about protection from reinfection and vaccines. Individuals who had Covid during the summer may still have some protection, but factors such as age, underlying conditions, and vaccination history play a role. While there is disagreement among scientists about the duration of this protection, it is generally believed to last between two to six months.
