The reporter provided no causality assessment. Company causality between covid-19 vaccine ad26.cov2.s, and antiphospholipid syndrome, reduced vascularization in left hand, heart issues going at 35 not 55-60 in her left ventricle, cut on hand with possible infection, issue with back of calves, and headache was related; between ustekinumab, and antiphospholipid syndrome, reduced vascularization in left hand, heart issues going at 35 and not 55-60 in her left ventricle, cut on hand with possible infection, issue with back of calves, and headache was related.
