A mix-up at an Emergent BioSolutions (EBS) - Get Report manufacturing plant in Maryland ruined 15 million doses of Johnson & Johnson’s (JNJ) - Get Report COVID-19 vaccine, forcing a halt in deliveries from the plant, according to published reports.
All shipments from the plant have been halted by the Food and Drug Administration, which is investigating the incident.
No currently distributed J&J vaccines were affected, but the plant is supposed to produce millions of the single-shot vaccines which are expected to help the United States ramp up its COVID-19 vaccinations in coming weeks.
Emergent BioSolutions signed a contract to product vaccine components for J&J last July in a deal valued at $480 million over the first two years, according to a statement issued at the time. The company has committed to manufacturing deals with several other pharmaceutical companies developing vaccines including Novavax (NVAX) - Get Report, Vaxart Inc. (VXRT) - Get Report, and Humanigen (HGEN) , Reuters reported.
In February, the company topped analyst estimates partly on the basis of its work producing vaccine components.
“Our differentiated CDMO [contract development and manufacturing organization] value proposition has been validated by our eight and counting CDMO COVID-19 partnerships and our growing pipeline and portfolio. We've carved out a leading position as a Tier 1 biologics CDMO organization,” CEO Robert Kramer said on a call with analysts at the time.
Shares of Emergent BioSolutions fell $7.61, or 8.2%, to $85.30 in after-hours trading.
