The Lake County Health Department is pausing the use of the Johnson & Johnson (Janssen) COVID-19 vaccine following guidance from the Centers for Disease Control (CDC), Food and Drug Administration (FDA), and as required by the Illinois Department of Public Health (IDPH). This was done out of an abundance of caution due to six cases of a rare and severe type of blood clot in individuals who received the Johnson & Johnson vaccine in the United States, out of over 6.8 million doses given. There are no known cases in our county. These events appear to be extremely rare, and COVID-19 vaccine safety continues to be a top priority. In the meantime, Lake County providers have been notified to use Pfizer and Moderna COVID-19 vaccines that are available.
