As for Ebola, there is absolutely no market at all, so the only reason we have two vaccines in late-stage clinical trials now, is actually because of a somewhat misguided fear.
Ebolast rääkides pole turgu ollagi. Ainus põhjus, miks kaks vaktsiini on kliiniliste katsete lõppfaasis, on tegelikult  mõneti alusetu hirm.
