I think you're misreading the supreme court ruling because you're misinterpreting the term unavoidably unsafe.

"In short, “unavoidably unsafe” is simply a legal term that means the manufacture is not liable because they cannot do anything to make the product safer. It does not mean that the product is dangerous and should be avoided."

This could apply to peanut butter because of peanut butter allergies. The manufacture is not liable for someone who dies of a peanut butter allergy when they eat peanut butter because this is not due to manufacturing defects but is due to the inherent nature of peanut butter being "unavoidable unsafe".

This does't mean peanut butter or vaccines are dangerous.
