New federal healthcare guidance announced Friday allows vaccinated middle and high school students, teachers and other educators to go maskless in K-12 indoor settings. Local public-health and school officials expressed hope that the relaxing of some COVID-19 restrictions by the federal Centers for Disease Control and Prevention could spark another round of vaccinations. However, the officials also expressed concern that the new guidance could take the COVID-19 vaccination honor system to a whole new level of accountability and potential unintended consequences. Vaccinated teachers and students don't need to wear masks inside school buildings, the Centers for Disease Control and Prevention said Friday in relaxing its COVID-19 guidelines. The changes come amid a national vaccination campaign in which children as young as 12 are eligible to get shots, as well as a general decline in COVID-19 hospitalizations and deaths.
