Health officials Tuesday in both Michigan and Wisconsin halted the use of the Johnson & Johnson COVID-19 vaccine pending the outcome of a federal investigation into six cases in which women who received the drug developed blood clots.

Locally, the Dickinson-Iron District Health Department announced Tuesday the Iron County clinic Friday that was to have offered the one-dose J&J shot now will use the Moderna vaccine, which requires two doses. Anyone with questions about the clinic can call the DIDHD at 906-265-9913 in Iron County or 906-774-1868 in Dickinson County.

The Florence County Health Department on Tuesday also canceled its outdoor drive-though clinic for the J&J vaccine that had been set for Friday in Florence, Wis.

Michigan Gov. Gretchen Whitmer’s office announced the temporary suspension of the single-dose vaccine after the Centers for Disease Control and Prevention and U.S. Food and Drug Administration recommended it throughout the country.

“The safety and health of Michiganders will always come first,” Whitmer spokesman Bobby Leddy said. “We will follow the FDA’s guidance to temporarily pause the Johnson & Johnson vaccine out of an abundance of caution, and adapt our vaccine strategy going forward until a further review of the data can be conducted.”

In Wisconsin, Department of Health Services Secretary Karen Timberlake said the clots appear to be extremely rare but that the state was pausing the use of the J&J vaccine.

The suspension on the J&J vaccine comes as Michigan is in the grips of another surge in COVID-19 cases and has the country’s highest infection rate over the past 14 days, according to Johns Hopkins University researchers.

It was not immediately clear how the suspension of the J&J vaccine would affect vaccinations statewide.

The University of Michigan had planned to vaccinate 7,500 students with J&J doses this week and next. About 3,700 of them will instead get Pfizer shots, but 3,800 appointments across three campuses were canceled and will be rescheduled once supply allows, spokesman Rick Fitzgerald said.

Michigan State University is able to honor all 2,400 appointments for students who were to have received the J&J vaccine this week because Ingham County will supply Pfizer doses instead, said school spokeswoman Emily Gerkin Guerrant.

J&J doses accounted for 199,000, or 3.7%, of the nearly 5.4 million shots that had been administered in Michigan as of Sunday. About 41% of people in the state age 16 or older have received at least one dose of a COVID-19 vaccine.

Whitmer has been calling for the federal government to send extra doses to help Michigan combat its surge in cases, but President Joe Biden’s administration has said it will stick to distributing vaccines to states proportionately by population.

Leddy said the issues with the J&J vaccine show it is more important than ever for the federal government to send additional Pfizer and Moderna vaccines to Michigan.

In Wisconsin, DHS Deputy Secretary Julie Willems Van Dijk said during a news conference that although the clots seem to be rare, the pause will give doctors a chance to review patient records and perhaps detect more vaccinated people who are suffering from them.

“We want to know what is the true number,” Van Dijk said. “This is a way to alert (physicians) to this unique situation . . . I hope Wisconsinites can hear those kinds of actions as ways to increase safety rather than making them more hesitant or fearful.”

She said she hopes the pause will last only a few days to a week and that state officials still hope to use the J&J vaccine at some point. COVID-19 still presents a greater risk than the vaccine, she said.

“(The clot) risk is about one in a million,” she said. “The risk of getting COVID is one in 10. The risk of dying of COVID is one in 600. It’s important to look at that whole picture.”

State health officials on Tuesday reported 922 new COVID-19 infections and 10 more deaths from the disease. The state’s infection rate continues to rise. The seven-day average daily case rate was 794 on Tuesday, up from 329 on March 7.
