The thing is that with such a sample, we don't really know

1. If the effect is real. i.e. had the patient not been given the injection, would his/her condition improve spontaneously.

2. Assuming the effect is real, what are the circumstances that make the treatment work for this person.

Not to be overly dismissive of the good work but it is too early to be optimistic about this given the above and the fact that the results were not replicated out of Sana suggest that there is a lot that we need to work out before this becomes a viable treatment for the masses.

The harms of hyping this up is that readers will get their hopes up and then be disappointed when things don't pan out as do most scientific endeavours. Overtime, readers will learn to distrust anything that is being reported because 90% of which do not translate to real world impact. It is hard to get the nuance that "science takes many many failures and iterations" to the public and the more likely outcome of such reporting is general distrust of science when things don't go the way that is hoped for.
