english: In your mind, Seth -- I mean, you must dream about this -- what is the kind of time scale on, let's start with HIV, for a game-changing vaccine that's actually out there and usable?
non_english: Kaj misliš, Seth? Verjetno kdaj sanjariš o tem ... Kdaj približno bi, začnimo recimo z virusom HIV, bilo lahko pripravljeno in dosegljivo uporabno cepivo?
