You are not supposed to ask that here. The vax deranged are a cult. Just blind adherence to the cult. Every ailment, symptom or death from an unspecified cause is caused by vaccine.

If Hotez were even to acknowledge that there may be a temporal-causal relationship between the vax and ASD, he would open the world to the suppressed evidence linking vaccines containing metal adjuvants to ASD.
Can’t have that.
