AZT has been shown to prevent transmission of the virus to unborn children. There's always a chance that HIV won't transmit and that some of those being treated might now have contracted HIV anyway, but even if women aren't compelled to take it there's no excuse not to make it available.

If the problem with supplying people with AZT is financial, that needs to be said up front. But for a government to be seen questioning whether HIV actually causes AIDS is extremely dangerous, because it twists people's minds.
