With the announcement from the Centers for Disease Control (CDC) this morning, the Iowa Department of Public Health (IDPH) has advised that all Iowa vaccine providers pause administration of the Johnson & Johnson COVID-19 vaccine until more details are confirmed.

The CDC and FDA are reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in individuals after receiving the J&J vaccine. Right now, these adverse events appear to be extremely rare.

All six cases occurred among women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination.

People who have received the J&J vaccine who develop severe headache, abdominal pain, leg pain, or shortness of breath within three weeks after vaccination should contact their health care provider.

Health care providers are asked to report adverse events to the Vaccine Adverse Event Reporting System here.

CDC and FDA will provide additional information and answer questions later today at a media briefing. A recording of that media call will be available on the FDA’s YouTube channel.

IDPH will provide further updates when more information is available.
