@dsmatthews@mastodon.online I wouldn't be so sure it'd be safe... The huge rise in allergies and other autoimmune disorders are likely a consequence of a lack of challenges to the immune system. And we don't even live *that* clean lives.

There's also the simpler issue that the protection isn't lifelong. So if the supply runs out - eg in a natural disaster - you now have a second disaster on your hands.
