A new COVID-19 variant, NB.1.8.1, is causing a rise in cases globally, particularly in the eastern Mediterranean, Southeast Asia, and western Pacific regions. The variant has been detected in US travelers from these areas. While the World Health Organization (WHO) designates it a "variant under monitoring," the global health risk is considered low, and current vaccines are expected to remain effective. This news comes as the US changes its COVID-19 vaccination recommendations, advising against shots for healthy children and pregnant women.
