Within a medical context there should be no connotations or even provoking of negativity, so IMO this
could be taken two (contradictory) ways:
- "Safer" is generally taken to mean "safe", but human nature can cause worry to change perspectives, imo even "SafeTransplants" carries a thought of "well, why wouldn't it be safe, why mention it at all?". So for some people it might not provide a definitive meaning and be potentially taken as "better than a lesser but not necessarily 100% safe"
- It can be taken as positive when viewed in a simple "good/bad" perspective - in that others are potentially bad, this one is good (safer). "Safer" things are generally taken as safe
That debate aside, who would you sell it to? Transplant companies are large so while that potentially means good money, are such operations available private with companies who would use this domain (ie non .gov, .nhs etc)? I think most/all have a brand name, like Bupa.
In conclusion, it's not a bad name, of course good keywords, but I'm not convinced you'll find a buyer given the specific context. Maybe do some outbound to the private companies, like Bupa etc. I think the name carries feasibility to get 3 to even 4 figures with a big corp (who like keyword domains), but I also do think it's potentially going to be a tough sell.
This is all my opinion and in this case is subjective/debatable.
Good luck
