Federal agencies are recommending pausing administration of the Johnson & Johnson COVID-19 vaccine while they investigate six cases of a "rare and severe" type of blood clot in people who have received the vaccine.
All six cases occurred in women between the ages of 18 and 48, and their symptoms started six to 13 days after vaccination, the Centers for Disease Control and Prevention and the Food and Drug Administration reported in a joint statement Tuesday morning.
Though adverse effects are "extremely rare," the CDC and the FDA are recommending pausing the vaccine until after the CDC holds a meeting of its Advisory Committee on Immunization Practices Wednesday on the blood clots.
Over 6.8 million doses of the Johnson & Johnson vaccine had been administered in the US as of Monday, according to the federal agencies. In Georgia, 256,100 Johnson & Johnson vaccines had been shipped to providers, according to the Georgia Department of Public Health. Georgia DPH does not list a breakdown of administered vaccines by manufacturer on its vaccine dashboard.
The CDC and FDA said they will make more information available later Tuesday.
