Another medical implication of the process is that it may permit lengthening the chains of harmful virus proteins, thus transforming them into neutral or beneficial materials. Actual germ killing methods may also develop from further investigation...
...after his death (usual incubation period: 14-21 days). Laboratory tests confirmed the suspicion. Soon four other cases developed. One patient died. These were Manhattan's first smallpox deaths in 35 years, the first cases in eight years.* And it was a particularly virulent form of the smallpox virus...
What causes Hodgkin's disease and how is it carried? One school considers it a form of cancer, with the body's own cells getting out of control. In 1944, investigators found "inclusion bodies" (possibly indicating virus infection) in affected tissues. The discovery was important: if the disease is really caused by a virus, a vaccine may eventually be developed...
...investigation's long-range aim: to isolate the cold virus and develop a vaccine. Each guest, on admission, snuffs a fluid up his nose. About 45%, used as controls, snuff only a harmless broth; the rest get virus-containing nasal washings from people with colds. Only about one-fourth of all the subjects actually come down with colds. Thus far, the doctors have no important new findings to report, but they think they have definitely established that wet feet, exposure to cold, etc. do not necessarily cause colds. The mischief is done by sneezers...
...epidemic or pandemic of influenza, the medical authorities at Yale recently vaccinated, free of charge, every student in the university. Harvard has not followed suit for a number of reasons. The only vaccines which have been developed so far are not effective against the dangerous pandemic form. Vaccinations for virus "A" do not protect against virus "B", and "B" vaccine is ineffective against a wave of "A" cases. For all types, the duration of the immunity is indeterminate, with the only sure fact being that the guarantee against contraction of the disease becomes less certain as time passes...
