Ensuring COVID-19 Vaccine Safety in the US

CDC and FDA have recommended a pause in the use of the Johnson & Johnson’s Janssen COVID-19 vaccine in the United States out of an abundance of caution, effective Tuesday, April 13. CDC will convene a meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday, April 14, to address this issue. People who have received the J&J/Janssen COVID-19 vaccine within the past three weeks who develop severe headache, abdominal pain, leg pain, or shortness of breath should contact their health care provider.
