Not sure from that article whether the milk naturally contains antibodies against it or if that only happens after the woman recovers from Covid (similar to the presence of antibodies in the plasma of recovered people, which is already being collected for therapeutic purposes). It sounds like the study itself is mostly looking to answer that question. I'd be very surprised if the non-convalescent women are already producing antibodies, but it's not impossible that their milk contains very generalized antibodies that can provide some immunity.

Further down the road, this may actually end up being a means by which to amplify the effect of any given vaccination while supplies are still limited. If you can vaccinate a nursing mother and then harvest her milk to produce a treatment that provides partial immunity, that would make them prime targets for those first few vaccines.
