BACKGROUND Influenza immunization still poses a critical challenge globally and specifically for tropical regions due to their complex influenza circulation pattern. Tropical regions should select the WHO's Northern Hemisphere or Southern Hemisphere recommended vaccine composition based on local surveillance. Analyses of influenza immunization effectiveness have neglected to account for the pro...
BACKGROUND Few trials have evaluated influenza vaccine efficacy (VE) in young children, a group particularly vulnerable to influenza complications. We aimed to estimate VE against influenza in children aged <2 years in Bangladesh; a subtropical setting, where influenza circulation can be irregular. METHODS Children aged 6-23 months were enrolled 1:1 in a parallel, double-blind, randomized con...
Influenza vaccination motivators among healthcare personnel in a large acute care hospital in Israel
BACKGROUND Vaccinating healthcare personnel (HCP) against influenza is important to prevent transmission and morbidity among patients and staff. METHODS We conducted an online survey assessing knowledge, perceptions and attitudes concerning influenza vaccination among HCP. Multivariate logistic regression was performed to identify independent predictors of vaccination. RESULTS The survey wa...
BACKGROUND Physicians of the Spanish Influenza Sentinel Surveillance System report and systematically swab patients attended to their practices for influenza-like illness (ILI). Within the surveillance system, some Spanish regions also participated in an observational study aiming at estimating influenza vaccine effectiveness (cycEVA study). During the season 2009-2010, we estimated pandemic in...
The seasonal influenza vaccine programs in many regions aimed to protect most vulnerable population, but current trivalent influenza vaccine does not provide sufficient effectiveness among people under high risk for severe outcome of the influenza. The vaccine herd effect (VHE) is the extra protection of non-immune high risk persons, with increase of immunity among vaccinated healthier persons ...
OBJECTIVES Influenza vaccine effectiveness (VE) and coverage data for sub-Saharan Africa are scarce. Using a test-negative case-control design, we estimated influenza VE annually among individuals with influenza-like illness presenting to an outpatient sentinel surveillance programme in South Africa from 2010 to 2013. A knowledge, attitudes and practices (KAP) influenza vaccine survey of progra...
This report updates the 2012 recommendations by CDC's Advisory Committee on Immunization Practices (ACIP) regarding the use of influenza vaccines for the prevention and control of seasonal influenza (CDC. Prevention and control of influenza with vaccines: recommendations of the Advisory Committee on Immunization Practices [ACIP]. MMWR 2012;61:613-8). Routine annual influenza vaccination is reco...
BACKGROUND Infections during pregnancy have the potential to adversely impact birth outcomes. We evaluated the association between receipt of inactivated influenza vaccine during pregnancy and prematurity and small for gestational age (SGA) births. METHODS AND FINDINGS We conducted a cohort analysis of surveillance data from the Georgia (United States) Pregnancy Risk Assessment Monitoring Sys...
BACKGROUND One dose of pandemic influenza vaccine Pandemrix (GlaxoSmithKline) was offered to the entire population of Finland in 2009-10. We conducted a prospective clinical cohort study to determine the vaccine effectiveness in preventing febrile laboratory-confirmed influenza infection during the influenza season 2009-10 and continued the study in 2010-11. METHODS In total, 3,518 community ...
During the 2009–2010 A/H1N1 influenza pandemic, pregnant women infected with the virus experienced excess morbidity and mortality when compared with other groups. Once a vaccine was available, pregnant women were a priority group for vaccination. Only a few studies have reported on the uptake of 2009 A/H1N1 influenza vaccine among pregnant women during the pandemic and none were from Asia. The ...
