It is unclear whether seasonal influenza vaccination results in a net increase or decrease in the risk for Guillain-Barré syndrome (GBS). To assess the effect of seasonal influenza vaccination on the absolute risk of acquiring GBS, we used simulation models and published estimates of age- and sex-specific risks for GBS, influenza incidence, and vaccine effectiveness. For a hypothetical 45-year-...

BACKGROUND Older adults and individuals with underlying chronic diseases are at increased risk of developing influenza-related complications and are target groups for seasonal influenza vaccination in many countries. In Germany, an annual national information campaign is conducted to increase influenza vaccination uptake in the target groups. However, data are lacking on knowledge and attitudes...

OBJECTIVES To test two hypothesized models of how anticipated affect, cognitive risk estimate and vaccination intention might influence vaccination uptake against seasonal influenza. METHODS The study collected baseline and follow-up data during the main influenza seasons (January-March) of 2009 and 2010, respectively, among 507 university students and staff of a university in Hong Kong. Foll...

OBJECTIVES Influenza is a significant worldwide public health issue. Knowledge and perceptions regarding the flu vaccination are associated with whether individuals obtain the vaccination. The purpose of this study was to examine how such perceptions were related to knowledge and self-efficacy regarding influenza and the flu vaccination in Vietnam and the US. METHODS College students (n=932) ...

OBJECTIVE The aims of the present study were to investigate the women's perspective on influenza infection and vaccination and to evaluate how they influence vaccine acceptability, in Korean women of childbearing age. METHODS This was a prospective study by random survey of women of childbearing age (20 to 45 years). They were asked to complete a questionnaire assessing their knowledge, attit...

Vaccination is the most effective strategy to prevent influenza. It is recommended that influenza vaccine be administered each year before the influenza season, i.e. from March to June, although for individuals at increased risk of severe influenza in whom vaccination was missed, vaccine may be administered later. For a review of the 2015 influenza season and ongoing real-time updates of the 20...

BACKGROUND Influenza vaccination for all children aged 6 months to 18 years has been recommended since 2008 to prevent flu-related morbidity and mortality. However, 2010-2011 influenza vaccine coverage estimates show under-vaccination in children of all ages. We examined predictors of influenza vaccination in Michigan during the 2010-2011 influenza season. PURPOSE To determine whether immuniz...

Pregnant women and their infants are at increased risk for severe influenza-associated illness (1), and since 2004, the Advisory Committee on Immunization Practices (ACIP) has recommended influenza vaccination for all women who are or might be pregnant during the influenza season, regardless of the trimester of the pregnancy (2). To assess influenza vaccination coverage among pregnant women dur...

INTRODUCTION Patients with end-stage renal disease (ESRD) are considered at higher risk of influenza-related complications and are listed worldwide among the subjects for whom yearly influenza vaccination is strongly recommended. However, influenza vaccination coverage of patients with ESRD is significantly lower than desired. AREAS COVERED This paper explores why compliance with official rec...

BACKGROUND Studies have shown that influenza vaccination during pregnancy reduces the risk of influenza disease in pregnant women and their offspring. Some have proposed that maternal vaccination may also have beneficial effects on birth outcomes. In 2014, we conducted an observational study to test this hypothesis using data from two large hospitals in Managua, Nicaragua. METHODS We conducte...
