It is the only Johnson & Johnsontemporarily suspended production at the facility that makes usable batches from its single-shot coronavirus vaccin. a new report said Tuesday.

The Netherlands-based facility has instead concentrated on creating a more profitable vaccine that targets another virus. The New York Times reported the story, using people who were familiar with it.

The pause in production at the Leiden facility, which began late last year and is expected to last a few months, could reduce the supply of J&J’s Covid vaccine by hundreds of millions of doses, one of those people told the Times.

The report does not indicate whether any vaccine stocks were affected by this company’s decision. J&J is preparing to have the Leiden plant restart Covid vaccine production in March, the Times reported.

J&J spokesman Jake Sargent didn’t directly comment on the Times’ article. CNBC was informed by Jake Sargent that J&J is focused on “ensuring our vaccines are available to people in need” and it fulfills its international obligations regarding Covid vaccine access.

J&J is continuing to deliver batches of the vaccine materials to sites that bottle and package doses, and “we currently have millions of doses of our Covid-19 vaccine in inventory,” Sargent said.

He said, “We are proud to have worked with our industry partners” and that they had developed the partnerships necessary for the production of COVID-19.
