Millions of doses of the Johnson & Johnson single-dose COVID-19 vaccine have now been administered in the United States, but the shot is now causing concern at the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC).
On Tuesday, both organizations issued a statement recommending a "pause" to the vaccine after six recipients in the U.S. reported cases of a rare and severe type of blood clot.
"The safety and well-being of the people who use our products is our number one priority," Johnson & Johnson said in a statement, "We have been working closely with medical experts and health authorities, and we strongly support the open communication of this information to healthcare professionals and the public."
The recommended pause comes just days before the vaccine was set to roll out in Europe, but the company has now made the decision to "proactively" delay the shipment.
Johnson & Johnson now suggests that you contact your healthcare provider if you have started to develop a severe headache, abdominal pain, leg pain, or shortness of breath within three weeks after receiving the vaccine.
The CDC has a robust website with all the latest information on the vaccines and can answer any questions you may have. Click here for more information.
