JEFFERSON CITY, Mo. — Johnson & Johnson’s COVID-19 vaccine is now paused in Missouri, according to the Missouri Department of Health and Senior Services.

The news comes after federal health officials began an investigation into potentially dangerous blood clots. Director Dr. Randall Williams said the state anticipates having more information after the federal advisory committee meets Wednesday.

“In an abundance of caution and as per federal guidelines, we are pausing vaccination with Johnson & Johnson’s Janssen vaccine until further notice in Missouri,” said Dr. Randall Williams, director of the Department of Health and Senior Services (DHSS).

“We anticipate having more information shortly to make further decisions about overall vaccine distribution in light of this new development and will continue to update citizens who have been vaccinated with the J&J vaccine after the advisory committee meets at the federal level tomorrow.”

Anyone who received the vaccine and develops a severe headache, abdominal or leg pain, or shortness of breath within three weeks should contact their health care provider.
