HAGÃ TÃA (The Guam Daily Post) â Guam could return to Pandemic Condition of Readiness 4, or normal conditions, as early as July 21 when the island is expected to reach its goal of fully vaccinating 80% of its adult population, Gov. Lou Leon Guerrero said on Monday. The public could expect the lifting of social gathering caps and occupancy limits by then, but the governor "still will mandate masks at this point, especially with the threat of the Delta variant," according to the governor's director of communications, Krystal Paco-San Agustin. GovGuam is tracking 79.75% herd immunity against Covid-19 by July 21. "We are prepared and we are confident that we will reach 80% or close to (it). You know, if we are 79.75%, what does that mean? I'm not gonna delay it just to get .25 or 300 more people because I know they will get vaccinated, but certainly we look forward to it," the governor said after a World War II memorial ceremony in Mangilao as part of Guam's 77th Liberation Day events.
