Vaccination data for Asian Americans are comparable to those for whites, possibly because they are reported in aggregate rather than for subgroups. We compared influenza and pneumococcal vaccination rates among eligible Asian Americans and white Americans, and for Vietnamese Americans as a subgroup, and assessed factors associated with these vaccinations.


Cross-sectional study of data collected from three ethnic groups over 4 years by telephone survey. Data were weighted for selection probability and population estimates and analyzed by multivariate logistic regression.


Vietnamese Americans had a higher rate of influenza vaccination (61%) than Asian Americans (45%) and white Americans (52%), and lower rate of pneumococcal vaccination (41%) than Asian Americans (56%), both lower than white Americans (67%).


When analyzed as a subgroup, Vietnamese Americans had a higher influenza vaccination rate, but a lower pneumococcal vaccination rate, compared to Asian Americans and white Americans, which may indicate that health behaviors and outcomes can differ widely among Asian subgroups. Analyses of preventive care measures in Asian Americans should focus on subgroups to ensure accuracy and quality of assessments.
