Novavax Inc., the vaccine developer that moved here a few years only to turn and move back to Maryland, soon will have no local operations. A filing says it will close its 24,000-square-foot manufacturing plant on Red Lion Road in Northeast Philadelphia, where it made Estrasorb. The reason? It lost the manufacturing contract with Esprit Pharma Inc., just purchased by Allergan Inc. No word on employees' fate. Its Malvern corporate office has been subleased to Puricore Inc.
