ThedaCare: Responds to recommend pause of Johnson & Johnson COVID-19 vaccine

NEENAH, Wis. – ThedaCare remains committed to the safe, reliable and effective distribution of COVID-19 vaccines for the people living in Northeast and Central Wisconsin. The health and safety of patients, team members and the community, is our number one priority.

On April 13, 2021, the Centers for Disease Control (CDC) and Food and Drug Administration (FDA) announced their recommendation of pausing the use of the Johnson & Johnson (Janssen) COVID-19 vaccine. Wisconsin Department of Health Services (DHS) has also instructed vaccinators to stop administering the Johnson & Johnson vaccine. The agencies are currently reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in individuals after receiving the Johnson & Johnson vaccine. According to the organizations, in the reported cases, a type of blood clot called cerebral venous sinus thrombosis (CVST) was seen in combination with low levels of blood platelets (thrombocytopenia). All six cases occurred among women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination. The instances appear to be extremely rare.

Agencies report the recommended pause is to ensure health care providers are aware of the potential for these adverse events and can plan for proper recognition and care. We
understand community members who have recently received the Johnson & Johnson vaccine may have concerns. People who have received the Johnson & Johnson vaccine and develop severe headache, abdominal pain, leg pain or shortness of breath within three weeks after vaccination should contact their health care provider.

Out of an abundance of caution, ThedaCare will pause in the use of the Johnson & Johnson COVID-19 vaccine. There were two ThedaCare clinics scheduled this week to administer the Johnson & Johnson vaccine, resulting in about 250 doses. Our teams are working with those community members and prioritizing to reschedule their vaccination appointment where they would receive the Pfizer or Moderna COVID-19 vaccines.

Vaccine updates will be available on the ThedaCare Facebook page and COVID-19 website.
