The U.S. Centers for Disease Control and Prevention and the Food and Drug
Administration said Tuesday they are recommending a "pause" in the use of the
single-dose Johnson & Johnson COVID-19 vaccine out of an "abundance of
caution" while an investigation is conducted into reports of apparently rare,
potentially dangerous blood clots.
In a joint statement on Tuesday, the two agencies said they are "reviewing
data involving six reported U.S. cases of a rare and severe type of blood
clot in individuals after receiving the J&J vaccine."
"In these cases, a type of blood clot called cerebral venous sinus thrombosis
(CVST) was seen in combination with low levels of blood platelets
(thrombocytopenia)," said Dr. Anne Schuchat, principal deputy director of the
CDC and Dr. Peter Marks, director of the Food and Drug Administration's
Center for Biologics Evaluation and Research. "All six cases occurred among
women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after
vaccination."
"Right now, these adverse events appear to be extremely rare," the statement
added.
Johnson & Johnson did not immediately respond to an email from NPR for
comment on the announcement.
More than 6.8 million doses of the Johnson & Johnson vaccine have already
been administered in the U.S., alongside tens of millions of doses of
vaccines produced by Pfizer-BioNTech and Moderna.
Similar concerns over rare blood clots have been raised over the
Oxford-AstraZeneca vaccine, which has been widely administered in the U.K.,
European Union and many other countries. Last week, the European Union's drug
regulator said the benefits of the vaccine outweigh its risks.
The pause is likely to complicate the U.S. vaccination drive amid an uptick
in new coronavirus infections and "vaccine hesitancy" among certain groups.
Tuesday's statement said that the CDC would convene an advisory committee on
Wednesday to "review these cases and assess their potential significance."
The FDA is also investigating the cases. The agencies said until the further
review is complete, "we are recommending a pause in the use of this vaccine
out of an abundance of caution."
