Gov. Gavin Newsom said Thursday California will still receive safe shipments of the Johnson & Johnson vaccine after a nationwide batch was discarded because of a manufacturing problem.
All current doses of the Johnson & Johnson vaccine are considered safe as they were produced in a Netherlands facility approved by federal regulators, the New York Times reported.
Newsom said at a press briefing that the state expects to receive slightly more than one million Johnson & Johnson doses from the Netherlands in the next three weeks.
“Beyond that,” he said, “it’s an open-ended question.”
A batch of up to 15 million doses of the Johnson & Johnson vaccine, also called the Janssen vaccine, reportedly was ruined in recent weeks because of quality-control problems at a Baltimore manufacturing plant, the New York Times reported Wednesday. Johnson & Johnson said in a press release that “one batch of drug substance” used in manufacturing the vaccine “did not meet quality standards.”
Some future production may be delayed while U.S. regulators complete an investigation.
The single-dose vaccine, which requires only refrigeration, has been viewed as critical to speeding vaccinations in California and across the nation in a race against emerging COVID-19 variants.
“We are working with the federal government to learn more about potential impacts,” California Department of Public Health spokesman Darrel Ng told CalMatters. “Maintaining the highest standards during vaccine production to ensure safe and effective vaccines is a paramount concern.”
Although Johnson & Johnson doses currently comprise a smaller part of California’s vaccination program than the Moderna and Pfizer vaccines, state officials expected supplies to increase significantly. The company projected that 100 million doses would become available nationwide by mid-year.
Earlier in March, Johnson & Johnson vaccines were not distributed nationwide as planned because manufacturing was slower than expected, Reuters reported.
Public health officials also are trying to overcome the skepticism of some Americans about the vaccine, which the FDA says is safe and effective in preventing death and serious disease. Studies show it does not provide as much protection as the Pfizer and Moderna vaccines.
Last month, five of California’s top government doctors received the Johnson & Johnson shot to boost public confidence. Public health officers from nine Bay Area counties also jointly expressed their confidence in the single-dose vaccine, noting — ironically, in retrospect — that “the best vaccine is the one you can get the soonest.”
