NKY Health Vaccination Clinics Pause J & J – Switch to Moderna Vaccine

The CDC and FDA have announced that they are reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in those individuals after receiving the J&J vaccine.

As of April 12, more than 6.8 million doses of the Johnson & Johnson (J & J) vaccine have been administered in the U.S. including doses in Northern Kentucky from NKY Health and pharmacies.  NKY Health has given 2,200 doses of J & J and has not had a report of this adverse event to date.

“Right now, these events appear to be very rare.  However, until we learn more from the FDA, CDC, and the Kentucky Department for Public Health, we are taking reasonable actions to pause the use of Johnson and Johnson vaccine in our vaccination clinics and will instead use the Moderna vaccine,” stated Lynne Saddler, MD, MPH, District Director of Health for the Northern Kentucky Health Department.

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.  Tell them your symptoms and that you have been vaccinated with J & J in the past three weeks so that it can be taken into consideration for your diagnosis and treatment.

Health care providers need to be aware of the potential for these adverse events in order to plan for proper recognition and management due to the unique treatment required with this type of blood clot. Health care providers should report adverse events to the Vaccine Adverse Event Reporting System at

COVID-19 vaccine safety is a priority for all of us in public health and health care,” stated Dr. Saddler, “This is why there is such an extensive reporting system in place to track and investigate adverse reactions and to pause the use of vaccine when necessary – even with extremely rare events – to make sure we all understand what is happening before proceeding.”
