Johnson & Johnson Inc. JNJ, +0.11% said Friday that it will resume enrolling U.S. participants in a late-stage clinical trial for its experimental COVID-19 vaccine following a recent halt.
Following a recommendation from the study’s data safety and monitoring board, J&J said it it is making preparations with the Food and Drug Administration to resume the study in the U.S. The clinical trial, however, is a global one. “Discussions with other regulators around the world to resume the clinical trial program are progressing,” J&J said in a statement.
Last week, J&J paused the study after one of the participants came down with an “unexplained illness.”
“There are many possible factors that could have caused the event,” J&J said. “Based on the information gathered to date and the input of independent experts, the company has found no evidence that the vaccine candidate caused the event.
