...Public Health Service suggests vaguely that 10 to 100 micromicrocuries of iodine 131 in milk is the "guidance" amount that small children should not exceed per day over a full year. Although the figures for milk in many Southern cities have been far above the top daily limit, the PHS is not alarmed because iodine 131 has a short half life* of eight days. When the Russians finish their current test series, most of the accumulated iodine 131-whether in milk, in air or on grass-will vanish in a few weeks. Other short-lived isotopes in the tropospheric fallout...
...hydrazine, a liquid that has also been used for rocket fuel. Isoniazid has been used by doctors since 1952 to arrest tuberculosis, and has helped cut the TB death rate in the U.S. from 30,000 a year to 10,000. Suspecting that it might also work for prevention, PHS four years ago began a test in Puerto Rico, Mexico and 16 states. Selecting 25,000 persons in daily contact with known tuberculars, researchers gave half of them daily doses of isoniazid; the other half got dummy pills as a control. Tabulation of the results showed that TB occurred five...
...trouble with the newly licensed vaccine is that it is effective against only Type I poliovirus. Said the PHS's Surgeon General Luther L. Terry: "I want to emphasize that an oral vaccine providing protection against all three types of poliomyelitis will not be available for some time. It is of the highest importance that vaccinations continue with the Salk vaccine, which is the only weapon we have today against all three types of polio...
...Terry said he expected the oral Type II vaccine to be licensed "in the near future," but that is now a relatively irrelevant matter. The issue is oral Type III. All vaccine batches are brewed separately by types, and samples are sent to the PHS's Division of Biologies Standards for testing of safety and potency. The toughest safety test is to inject vaccine directly into the brains of monkeys. If autopsies show any appreciable virus damage to the monkeys' nerve centers, PHS orders the vaccine discarded. Type I vaccine has already passed this rigorous test the required...
