 Why was Macklin against having an antitoxin to combat the virus?
But Macklin is exactly what we need for a quick, dramatic test. "But now Macklin—" Elliot Macklin had inherited the reputation of the late Albert Einstein in the popular mind. No one knew whether his Theory of Spatium was correct or not because no one had yet been able to frame an argument with it. The government took up a lot of his time using him as the symbol of the Ideal Scientist to help recruit Science and Engineering Cadets. For the past seven years Macklin—who was the Advanced Studies Department of Firestone University—had been involved in devising a faster-than-light drive to help the Army reach Pluto and eventually the nearer stars. "No, Harold, it isn't," Macklin admitted. "I would have said the common cold," Macklin replied, "but I suppose from what you have said you mean headaches." "Aspirins would still be used to reduce fever and relieve muscular pains," Mitchell said. "There are a number of different causes for headaches—nervous strain, fatigue, physical diseases from kidney complaints to tumors, over-indulgence—but there is one effect of all of this, the one real cause of headaches," Mitchell announced. "The virus," Ferris explained, "can easily be localized and stabilized. A colony of virus in the brain cells will relax the cerebral vessels—and only the cerebral vessels—so that the cerebrospinal fluid doesn't create pressure in the cavities of the brain." "On rats, on chimps...." Unless we can produce quick, conclusive and dramatic proof of our studies we can get no more financial backing. "When your heart stops, your blood pressure goes to its lowest point," Mitchell said. As I said, the virus is self-stabilizing. Ferris and I are confident that there is no danger.... By established periodic cycle he should be suffering hell right now, shouldn't he? If it wasn't enough to go to the press with, it wasn't enough to try and breach the trustees with. The public will hand down a ukase demanding our virus, just as they demanded the Salk vaccine and the Grennell serum." "Most known narcotics," she admitted, "but evidently you have discovered something new. Jerry, their control in the experiment, who was practically Dean's twin except that he had received no injection of the E-M Virus, was stomping up and down punching his fingers through the wire, worrying the lock on the cage.
 He didn't want the headaches to return.
 He feared the additional side-effects of the antitoxin.  He didn't want the headaches to return.  He enjoyed the attention he was receiving.  He enjoyed the newly found free time he had.
