Vaccine news doesn’t mean Congress is off the hook

Monday’s very favorable news from Pfizer Inc. – that its COVID-19 vaccine candidate was found to be more than 90% effective at preventing disease in early clinical trial results — raises hopes for a day, and soon, the pandemic will be behind us. It is also just one of the many vaccines that are under development. With such good news, it may be tempting for Congress to conclude that a major fiscal relief effort is no longer needed. That would be a mistake.
