'Sending millions of people back to work without protection or testing would only result in tragedy! Thirty-four million workers are over 55; 10 million of them over 65. Millions more suffer from chronic problems.The proposal to test people’s blood & then issue back-to-work certificates if they have the right antibodies is mere fantasy at the moment. Washington has allowed more than a hundred different firms to sell serological kits without human trials or FDA certification. The sprawling scientific vaccine experiment lacks coordination, funding, and no one knows how long its conferred immunity would last. We are living in an indefinite lock-out, facing an administration that sets a higher priority on destroying the Postal Service than it does on organizing a crash program to produce the tests, safety equipment, and antivirals that will allow the U.S. to return to work.'
