Introduction. There is little data on vaccination coverage among adults. The most recent national data on diphtheria/tetanus/polio vaccination date back to 1990. We present an analysis of data from the 2002 Health and Social Protection Survey. Methods. The survey was conducted on a representative sample of households in metropolitan France. Information on vaccination was collected using a self-administered questionnaire among individuals aged 16 years or older. Results. The proportion of individuals vaccinated within the past 15 years—that is, considered to be protected by vaccination—was 71.2% [95% CI: 70.0–72.3] for tetanus, 41.9% [95% CI: 40.7–43.2] for polio, and 33.7% [95% CI: 32.4–35.0] for diphtheria. Coverage rates were lower among women and older adults, among those with low educational attainment, those without supplemental health insurance, and those living in low-income households. Unskilled workers, farmers, artisans and merchants, and residents of the Northern and Mediterranean regions also had lower coverage. Discussion-Conclusions. Although a comparison with other data sources suggests an underestimation due to the self-reported nature of the collected information, vaccination coverage among adults appears insufficient for all three vaccines, particularly among women and older adults. Further investigations are underway to better understand variations in vaccination coverage based on socioeconomic conditions. (R.A.)
