The disease is due to a cosmopolitan virus called Rickettsia prowazeki,* which dwells in the intestines of the filthy little insects. Vaccines made from dead typhus viruses provide immunity from the disease, but such vaccines are difficult to make, for Rickettsia prowazeki cannot be easily cultured in artificial mediums, thrives and multiplies best in its natural habitat.

More than 60% of the mice with "colds" survived the sleeping sickness injections; of the healthy, untreated mice, less than 25% survived. It was not the nasal bacteria which saved the mice, said Dr. Armstrong. Rather the bacteria stimulated production of defensive leucocytes (white blood cells) which poured into...
...their instincts another. But in Rocket to the Moon psychological dislocations result from a clash of temperaments, a lack of drive. And Odets will not stay with his plot. He pursues a mystical theme which overrides it: the need for love to vitalize human lives. Inoculated with this virus, his characters cease to be individuals in a specific situation, turn into orators, poets, philosophers who halt the action to harpoon the cosmos...
