Bioweapons aren't all that effective in general for the reasons seen here: they're too slowly acting, to easy to treat, and not as lethal as, say, chemical weapons (which are also not that effective as weapons). Biological weapons are most dangerous as terror weapons.
I am not sure I agree completely. Yes, the panic they induce ( and that media happily augment ) is in itself dangerous, but.. well, weaponized ebola has apparently been in existence for a while. What makes you think progress was not made since then to.. add new traits to existing strains?
I hate to say anything more, because we would easily move into wild speculation territory.
