Press Secretary Trixie Cruz-Angeles said this comes after government data showed that the country is "6 percent away from the wall of immunity." "The state of calamity is extended for possibly three months but only for the purpose of preserving the benefits under it such as but not limited to the indemnification, emergency procurement, special risk allowance for healthcare workers," she said in a Palace press briefing. "We're happy to announce that we are 6 percent away from the wall of immunity. That's why malakas na ang loob natin for face masks (we are confident enough to make face mask use voluntary)," she added. President Ferdinand "Bongbong" Marcos Jr. on Monday signed Executive Order No. 3 allowin
