The use of the Johnson & Johnson vaccine has been paused because 6 women had blood clotting problems, one of them fatal. This was out of 7 million doses given so far.
The pause will result in avoidable deaths due to the delay in getting the population vaccinated.
An evidence based approach would take into account that women are well known to have more clotting problems than men and that the combination of smoking and oral contraceptives results in a much higher incidence of clotting problems.
There is no reason at all to pause the use of the J&J vaccine in men, as there have been no cases involving men.
There is very little justification for the pause in women, but if the very rare events are a concern, then continue the use of the J&J vaccine for men and give women Moderna or Pfizer while the issue is studied, especially if they have other risk factors like past clotting problems or they smoke or take hormones.
But it is idiocy to leave J&J vaccine on the shelf while people are still dying.
