On April 13, 2021, the FDA and CDC advised suspending use of the Johnson & Johnson adenovirus-based COVID-19 vaccine while the agencies investigate 6 cases of cerebral venous sinus thrombosis (CVST) and thrombocytopenia that occurred following administration of the vaccine. In an April 14 emergency meeting, the Advisory Committee on Immunization Practices (ACIP) recommended continuing the suspension until more data become available. About 7 million people in the US have received the Johnson & Johnson vaccine.

On April 23, 2021, on advice from the Advisory Committee on Immunization Practices (ACIP), the FDA and CDC recommended that use of the Johnson & Johnson adenovirus-based COVID-19 vaccine resume despite its association with development of thrombosis with thrombocytopenia syndrome (TTS). Administration of the vaccine had been paused on April 13 because of 6 reports of TTS, but after completing a data review that identified a further 9 cases associated with the formulation, the agencies concluded that the benefits of the vaccine outweighed its risks. About 7.98 million doses of the...

The FDA has required updates to the boxed warnings in the labeling of the Janus kinase (JAK) inhibitors tofacitinib (Xeljanz, Xeljanz XR), baricitinib (Olumiant), and upadacitinib (Rinvoq) describing increased risks of major adverse cardiovascular events, malignancy, thrombosis, and death with their use. The new warnings were prompted by the results of a postmarketing safety trial with tofacitinib and were added to the labels of baricitinib and upadacitinib based on the presumption of a class effect. The tofacitinib package insert had contained a boxed warning about an increased...
