Distribution of the one-dose vaccine have been paused in the US while scientists look into a rare blood-clotting syndrome
US health officials paused distribution of the Johnson & Johnson Covid-19 vaccine as scientists investigate the potential link between rare cases of blood clots and the potentially life-saving vaccine. Currently, the clotting “syndrome” appears to affect less than one in a million people who receive the vaccine.
Among more than 7.2m vaccine doses, scientists are investigating six cases of women between 18 and 48 who developed a rare blood clot, one that critically needs to be treated without heparin, a common blood thinner.
