- 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.
- 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.
- Pregnant women are at risk for severe influenza-related complications; however, only 52% reported receiving an influenza vaccination during the 2013–2014 influenza season. Text4baby, a free national text service, provides influenza vaccination education and reminders to pregnant women. This study examined reported influenza vaccination during pregnancy among Text4baby participants who reported receiving influenza messages and women who reported never participating in Text4baby.
- 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.
- 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.
- The 2009 pandemic influenza A (H1N1) virus (2009 H1N1) was first identified in April 2009 and quickly spread around the world. The first doses of influenza A (H1N1) 2009 monovalent vaccine (2009 H1N1 vaccine) became available in the U.S. in early October 2009. Because people with asthma are at increased risk of complications from influenza, people with asthma were included among the initial prioritized groups.
