The Food and Drug Administration (FDA) has revoked authorization ofΒ Johnson & Johnsonβs Covid vaccine after it was paused over rare blood clot concerns, which sent demand plummeting.Β
The move was not unexpected because J&Jβs parent company Jannsen had requested that federal regulators at the FDA withdraw authorization for its vaccine after it was revealed that the last tranche of doses β about 12.5 million β had expired.
As of year three of the Covid pandemic, nearly 231 million Americans have received either one J&J shot or two doses of an mRNA vaccine from Pfizer orΒ Moderna.
