- Influenza is a major cause of morbidity and mortality among adults. The most effective strategy for preventing influenza is annual vaccination. However, vaccination coverage has been suboptimal among adult populations. The purpose of this study is to assess trends in influenza vaccination among adult populations.
- Routine influenza vaccination of healthcare personnel (HCP) can reduce influenza-related illness and its potentially serious consequences among HCP and their patients. Influenza vaccination has been routinely recommended for HCP since 1984.
- 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.
- During annual influenza epidemics, rates of serious illness and death are higher among those who have medical conditions, such as pulmonary disease, diabetes, or heart disease, which place them at increased risk of influenza complications. Annual influenza vaccination was recommended for people with high-risk conditions as early as 1960.
- 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.
- In 2009, the quadrivalent human papillomavirus (HPV) vaccine was licensed by the U.S. Food and Drug Administration for use in men/boys aged 9–26 years. In 2009, the Advisory Committee on Immunization Practices (ACIP) provided a permissive recommendation allowing HPV vaccine administration to this group.
- Seasonal influenza vaccination routinely has been recommended for healthcare personnel (HCP) since 1984. The influenza A (H1N1) 2009 monovalent vaccine (H1N1 vaccine) became available in the U.S. in October 2009.
