Interesting. Let's steel-man your annecdote.

We have a use case for an adult, not as a random preventative, but as a solution to a recurring problem. If this person has been properly informed to the risks, which have been adequately studied using long-term, double-blind, placebo-controlled studies, then what objection could I have?

None.

In that case I would need to augment my argument that "all vaccines are scams."

So let's see those studies ;-).

They better be pretty damn RIGOROUS studies if they are going to inject kids, who's development may be affected.

Glad your friend found relief regardless.
