Maassab, professor of epidemiology at the University of Michigan School of Public Health, has proved 93 percent effective in a major study of 1,600 children across the country. The vaccine triggers an early, local antibody response in the nasal passages. Influenza kills 20,000 people each year in the United States alone.
Researchers at the University of Maryland School of Pharmacy found poor folic acid dissolution in six prenatal prescription multivitamins they tested, raising questions as to whether or not absorption by the body is complete. Tests of nine prenatal prescription multivitamins found six products did not release at least 75 percent of the amount of folic acid listed on their labels in one hour, an industry standard set in 1995.
