Federal health officials have now confirmed 28 cases, including six in men, of a rare blood clotting disorder in adults who have received the Johnson & Johnson Covid-19 vaccine... The figure is an increase from the 15 confirmed cases, all of which were in women, that were reported at last month’s meeting. Although officials have now identified a handful of cases in men, women - especially those between the ages of 30 and 49 - appear to remain at elevated risk. “The trend is that the reporting rates are higher in females compared to males in all age categories,” Dr. Shimabukuro said at the meeting.
