"Reasonable" based on what risk/effect-analysis? For what age group? I don't know how many 60 year olds browse HN but I'm not going to take either experimental treatment for a disease I don't even have any reason being scared of, based on the actual data we have. The more hysterical part of society can argue about this and inject themselves with whatever they like for all I care, just leave the rest of us out of it. Not everyone wants to live in fear and under dystopian rights restrictions.
