Information on the lot/batch number has been requested.; Sender's Comments: Collapsed with left sided hemiparesis/suspicion for stroke are as consequences of basal ganglia hemorrhage with edema, which is caused by worsening of hypertension.  Low platelet also contributes to brain hemorrhage. All these serious events are unrelated to the vaccine use.
