Contra Costa County public health officials are pausing the use of the Johnson & Johnson (Janssen) vaccine as it undergoes further review for a possible side effect, but the County doesn’t anticipate cancelling any of its vaccination appointments, saying the Janssen vaccine is a “very small” part of the County’s allocation.
Federal officials called for a pause in the use of the Janssen vaccine while regulators study the possibility that it can cause blood clots. Out of 6.8 million administered doses of the vaccine in the U.S., there have been six reported cases of a “rare and severe” type of blood clot, according to the Center for Disease Control and Prevention (CDC).
Contra Costa County Health Services (CCHS) is continuing to administer the Pfizer and Moderna vaccines.
“CCHS does not anticipate cancelling any of its vaccination appointments at this time,” the County said, adding that it is not aware of any reported cases of abnormal reactions to the Janssen vaccine in the County.
