Don't take it lightly. If you are vaccinated then KN95 mask is very important and useful.
After the Centers for Disease Control and Prevention issued new mask guidance recommending that fully vaccinated people wear masks indoors in areas with high transmission, states quickly reacted.
Nevada issued an emergency order requiring people in 12 of 17 counties — whether they're vaccinated or not — to wear KN95 masks in public indoor spaces. As we know day by day cases are going to increase so that precautions is very important. We should use KN95 masks and sanitizer.
