(ANSA) - WASHINGTON, MAR 2 - "It is not the time to let your guard down": Joe Biden said about the obligation to mask, after two American states, Texas and Mississippi, announced the lifting of all restrictions .
"Three weeks ago I announced that we would have enough vaccines for all Americans by the end of July, today, with efforts to boost production, I say we will have enough for all Americans by the end of May," assured the president speaking from White House. Biden then called "a wartime effort" the White House-mediated collaboration between two of the world's leading pharmaceutical companies, Merck and Johnson & Johnson, generally rivals, to accelerate the production of single-dose vaccines against Covid-19. The president explained that he had invoked the 'defense production act', a war law from the time of the conflict in Korea, to adapt two Mercks plants to produce the vaccine. (HANDLE).
