FDA pulls J&J COVID vaccine after 19 million Americans receive it.

The FDA has revoked authorization of Johnson & Johnson's COVID-19 vaccine due to plummeting demand after it was paused over rare blood clot concerns. J&J's parent company Jannsen had requested that federal regulators withdraw authorization for its vaccine after it was revealed that the last tranche of doses had expired. Vaccination fatigue has swept the US, with millions of Americans frustrated by the fact that a shot does not guarantee immunity from the virus but rather protects against severe illness. With a renewed wave of demand for J&J's single-dose vaccine highly unlikely, coupled with a beleaguered history of production hiccups and health concerns that severely eroded public trust, the pharmaceutical company has opted to step away from the COVID-19 vaccine field.
