That's another good point. So there's a number of mechanisms at work here:

1. S proteins and toxicity causing damage to tissues directly such as nervous system
2. S protein caused by repeated dosage over time causing over specification of immune response and VAIDs
3. Coagulation from spikes and blood cell damage
4. Developmental issues caused by gene therapy affecting births and cancers
5. Some evidence of effects on reproductive system directly such as changing women's cycles.
