The U.S. will reportedly recommend that COVID booster shots be administered to Americans of any age eight months after they have received their second doses, amid the spread of the highly contagious Delta variant. Two sources told the Associated Press on Tuesday that an announcement on a recommendation for a booster shot is expected to take place this week to offer U.S. residents extra protection against COVID as the pandemic continues. Federal health officials have been looking at whether an extra shot will be needed for Americans as soon as this fall, with case numbers having risen in several states over the last month and Florida reporting record positive COVID tests and hospitalizations.
