- Pregnant women are at increased risk for severe illness from influenza and influenza-related complications. Vaccinating pregnant women is the primary strategy to protect them and their infants from influenza. This study aims to assess influenza vaccination coverage during three influenza seasons (2012–2015) from a national probability-based sampling survey and evaluate potential factors that influence vaccination uptake among pregnant women.
- English-speaking non-Hispanic Asians (Asians) in the U.S. include populations with multiple geographic origins and ethnicities (e.g., Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese). Health behaviors and outcomes can differ widely among Asian ethnicities, and highlight the importance of subgroup analysis. Aggregating Asians may mask differences in influenza vaccination across various ethnicities.
- Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination has been recommended for adolescents in the U.S. since 2006. Information on Tdap vaccination by provider recommendation is limited. The purpose of this study is to assess recent Tdap vaccination by provider recommendation status among adolescents aged 13–17 years.
- Shingles (herpes zoster) causes substantial morbidity, especially among older adults. The shingles vaccine has been recommended for people aged ≥60 years since 2006. This study assessed recent shingles vaccination at national and state levels among adults aged ≥60 years.
- The Advisory Committee on Immunization Practices recommends a single dose of tetanus, diphtheria, and acellular pertussis vaccine (Tdap) for adults followed by tetanus and diphtheria toxoids (Td) booster doses every 10 years thereafter. This study assessed recent Td and Tdap vaccination among adult populations.
- Underinsurance is a barrier to vaccination among children. Information on vaccination among adults aged ≥18 years by insurance status is limited. This study assesses vaccination coverage among adults aged ≥18 years in the U.S. in 2012 by health insurance status and access to care characteristics.
- Foreign-born persons are considered at higher risk of undervaccination and exposure to many vaccine-preventable diseases. Information on vaccination coverage among foreign-born populations is limited.
