Janssen COVID-19 Vaccine (Johnson & Johnson)

alert icon

CDC and FDA have recommended a pause in the use of the Janssen (Johnson & Johnson) COVID-19 vaccine in the United States out of an abundance of caution, effective Tuesday, April 13. Of the 6.8 million Janssen COVID-19 vaccine doses administered in the United States to date, six cases of a type of blood clot called “cerebral venous sinus thrombosis” (CVST) were seen in combination with low levels of blood platelets (thrombocytopenia). CDC will convene a meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday, April 14, to further review these cases and assess their potential significance. FDA will review that analysis as it also investigates these cases.

If you are a COVID-19 Vaccination Provider with Janssen (Johnson & Johnson) vaccine:

  1. Mark any Janssen/J&J vaccine in your inventory “Do not use. Awaiting guidance.”
  2. Continue to store the vaccine in the refrigerator between 2°C and 8°C (36°F and 46°F).
  3. Follow vaccine storage practices and continue to monitor and document storage unit temperatures.

Report Adverse Events

Adverse events that occur in a recipient after COVID-19 vaccination are required to be reported to the Vaccine Adverse Event Reporting System (VAERS). FDA requires vaccination providers to report vaccine administration errors, serious adverse events, cases of multisystem inflammatory syndrome, and cases of COVID-19 that result in hospitalization or death after administration of COVID-19 vaccine under an EUA. Reporting is encouraged for other clinically significant adverse events, even if it is not clear that a vaccine caused the adverse event. Complete and submit reports to VAERS onlineexternal icon.

For further assistance with reporting to VAERS, call 1-800-822-7967.
