WHERE WILL J&J PRODUCE MILLIONS OF VACCINES? Multiple Johnson & Johnson partners chipping in on the coronavirus vaccine are mired in questions about their factories’ processes this week, stoking fears that J&J could miss its ambitious vaccine goals — a worry that the company strongly dismisses. J&J still aims to deliver 100 million doses by the end of May, it said in a statement where it promised to take a more direct role in supervising production at contract plants. What happened: First, concerns about hygiene at a Merck plant broke open in a whistleblower complaint about FDA inspections that alleged unsanitary work conditions at the Durham, N.C. facility that is slated to help produce J&J vaccine substance. “We produce our medicines and vaccines to the highest standards, in full compliance with regulations and good manufacturing practices,” Merck said in a statement. Within hours there was another hit — J&J’s Maryland partner to produce the vaccine, Emergent BioSolutions, had mixed up ingredients with another vaccine, ruining millions of shots. Senior administration officials knew about potential Emergent problems for more than a week but the batch problem came to light late last week, Erin Banco, Rachel Roubein and Sarah reported. Emergent said it has isolated the batch and will dispose of it. “Discarding a batch of bulk drug substance, while disappointing, does occasionally happen during vaccine manufacturing, which is a complex and multi-step biological process,” it said. What’s next: A senior administration official tells us it could take a matter of days or weeks to get Emergent back on track — and eventually authorized by the FDA — to produce and release J&J doses. In the meantime, the company has help to fill and finish vaccine vials, but no one cleared to help with the key ingredients themselves. Plus, AstraZeneca — at the center of its own troubles about vaccine confidence — has also partnered with Emergent to produce millions of shots. The company said it is “are aware of the reports regarding the facility and we understand Emergent is investigating the matter." FDA: MODERNA CAN FILL VIALS WITH MORE VACCINE — FDA announced late Thursday that Moderna is now allowed to put up to 15 doses of vaccine in each vial, a 50 percent increase, and that vaccinators can, when possible, extract an extra 11th dose from existing 10-dose vials. The agency also said Moderna's vaccine can be kept at room temperature for 24 hours, up from 12 hours, and that once a vial is opened, vaccine can now be administered for 12 hours, up from six hours. All those changes "will help provide more vaccine doses to communities and allow shots to get into arms more quickly,” FDA vaccine regulator Peter Marks said in a statement. NIH LAUNCHES TRIAL OF MODERNA VARIANT VACCINE — The National Institutes of Health said Wednesday it is enrolling adults in an early-phase clinical trial to evaluate a Moderna vaccine targeting a more contagious coronavirus variant first found in South Africa. The study aims to enroll about 210 adults without a known history of a Covid-19 infection in Atlanta, Cincinnati, Nashville and Seattle by the end of April. FDA AUTHORIZES TWO MORE OTC COVID-19 TESTS — The FDA announced late Wednesday it authorized several rapid Covid-19 tests meant to be used to repeatedly screen asymptomatic people, a move that will expand the United States’ arsenal of tools to detect the virus as states reopen schools and workplaces. The OTC tests, made by Quidel and Abbott, can now be used by people to repeatedly screen themselves for the virus at home. Abbott said it plans to sell the tests to retailers at a per-test cost in the single digits, but it is unclear what price consumers eventually will pay. Harvard University epidemiologist Michael Mina — who has advocated for at-home antigen tests — called the authorizations “a major milestone” that he hopes will help slow the spread of Covid-19 and its variants by enabling infected people to quickly isolate themselves. FDA laid the groundwork for the new authorizations in mid-March when senior regulators announced they would allow some diagnostics manufacturers to market Covid-19 tests for regular at-home use before companies complete studies on how well the tests perform in people without symptoms. NIH and CDC also announced this week the launch of a study where a month of free Covid-19 antigen tests will be given to up to 160,000 people in Pitt County, N.C., and Chattanooga, Tenn., to explore if three-times-a-week self-testing can cut down on Covid-19 infections. |
