Citing an "abundance of caution," U.S. health authorities with the Centers for Disease Control and Prevention and the Food and Drug Administration are calling for a temporary pause in the distribution of Johnson & Johnson's COVID-19 vaccine over "extremely rare" cases of blood clots.
"As of 4/12, 6.8m+ doses of the J&J vaccine have been administered in the U.S. CDC & FDA are reviewing data involving 6 reported U.S. cases of a rare & severe type of blood clot in individuals after receiving the vaccine. Right now, these adverse events appear to be extremely rare," an FDA statement on Twitter read.
