I'm a pureblood myself, haven't had a vaccine in quite a bit longer than you've been alive.
But I don't advocate that for anyone else, I don't have anything against vaccines, just prefer not to use them myself.
But I do question the bombardment of very young children with so many at once before their immune systems even begin to fully develop for themselves, I wonder at the wisdom of this.
Above all, I just want everyone to think about it for themselves and not just blindly let some 'authority' do their thinking for them so they don't have to.
That's my view on the matter.
