The program of mass inoculation of adults in Oakland County, Michigan, with monovalent influenza A/New Jersey/76 virus vaccine was monitored. A stratified random sample of participants was selected, and telephone interviews were conducted two days after inoculation. The group of vaccines differed from the overall county population in that it had a higher percentage of females and more of the vaccinees were older, better educated, and of higher income. Minor complaints following vaccination were relatively frequent, particularly sore arm. All complaints were significantly more frequent in females than in males, and among females, the group younger than 40 years reported these complaints most often. Since neither utilization of the vaccine nor complaints following vaccination were uniformly distributed, it was concluded that population-based studies are needed for proper assessment of vaccine-related effects.

From July 1, 1980 to December 2, 1982, all individuals at autopsy at the University of Michigan Medical Center greater than or equal to 65 years of age and selected individuals less than 65 years of age were examined for neuritic plaques and neurofibrillary tangles. Sections of the hippocampal, parahippocampal temporal gyrus, and fusiform gyrus were examined. In a total population of 199, each individual was classified as having none, few, or many of each lesion. The frequency of the joint presence of many plaques and tangles increased monotonically after age 71 years. There was no significant difference in the joint distribution of these lesions with sex or race. There was a strong correlation between the presence of one lesion and the other; the correlation for the two lesions was similar for males and females, but for blacks, it was significantly higher than for non-blacks. The distribution of these lesions in autopsy populations may be useful in identifying other related hypothetical risk factors for dementia of Alzheimer's type.
