Why couldn’t Stukov’s cure save Haven?

Haven presents Raynor with a choice between protecting the colonists and helping the protoss purge them. Remembering Stukov makes that choice look incomplete: if a serum had reversed his infestation, why not bring it here?

The colony-protection option offers a useful starting point. Its promise is time for Dr. Hanson to develop a cure. It does not present a finished treatment ready for distribution. Before Raynor can put hope to the test, he has to keep the colony from being destroyed.

A precedent is not a relief operation

Blizzard addressed the apparent contradiction in Creative Development Q&A, Part 9. Writer Brian Kindregan points to an imminent outbreak, a populous colony and a fleet ready to burn it down. A serum used on one person years earlier would not be available for the fleet to acquire and deploy in time. Its commander was not interested in using it, either.

That explanation preserves the earlier treatment while challenging the jump from “this has worked” to “we can do it here.” Knowing about a treatment does not put it aboard a ship. Having it aboard would still leave the problem of reaching the people who need it. The history of one patient cannot, by itself, supply those missing steps.

This is also why “Raynor forgot Stukov” is an inadequate summary of the answer. Kindregan explains practical constraints on the choice. He does not supply a missing scene in which Raynor privately works through them. The distinction matters: a writer's explanation can clarify a story without becoming dialogue that the character actually spoke.

What fighting the fleet can achieve

The protection route makes the need for time tangible. Raynor's forces must fight the protoss; the image below shows combat during that mission. Research cannot proceed on its own timetable while another force is destroying the place it is supposed to save.

Winning that battle and proving a treatment are different achievements. Defeating the fleet would address the immediate military threat. It would not, by itself, be a medical result. Equally, the absence of an immediately usable remedy does not establish that reversing infestation is impossible under every circumstance.

The answer leaves immunity conditional

Kindregan also suggests that the zerg have probably evolved immunity to the old serum. The qualifier matters. This does not establish a date when all zerg became immune, or a universal rule that no treatment can ever work again.

Turning that possibility into certainty would flatten the dilemma. If the serum simply could not work, questions of access, distribution and the commander's willingness would drop away. The actual answer keeps several obstacles in view.

Haven is uncomfortable because a possibility and an available rescue are separated by people, resources and time. Choosing to protect the colony means making room to pursue that possibility. Stukov's earlier treatment gives the question force; it does not remove the cost of answering it here.
