What if the influenza vaccine did not offer such variable protection?
This study looked at the impact of reducing the variability in responses to the influenza vaccine across the population. Protection from the vaccine can vary significantly from person to person due to differences in immune systems, body types, and other factors. The authors compared the projected cases, direct medical costs, and productivity losses at the 30%, 50%, and 70% efficacy rates.

Comparative effectiveness of high-dose versus standard-dose influenza vaccine among patients receiving maintenance hemodialysis.
This study compared outcomes of routine dialysis patients who received either the standard dose vaccine (SDV) for influenza or a high-dose vaccine (HDV). Out of 22,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. There did not seem to be any additional protection provided by the HDV for all-cause mortality or influenza-related outcomes.

Derivation and validation of a clinical decision guideline for influenza testing in 4 US emergency departments.
This study looked at which patients should be tested for influenza among adult emergency department (ED) patients with fever or respiratory symptoms who met criteria for antiviral treatment per 2013 CDC guidelines. A prospective cohort study was conducted at 4 US EDs from November 2013 to April 2014. All 1941 enrolled participants were tested for influenza using polymerase chain reaction (PCR), and 183 patients (9.4%) had influenza. The CDC clinical decision guidelines (CDGs) for influenza testing includes new or increased cough (2 points), headache (1 point), subjective fever (1 point), and triage temperature >100.4F degrees. The CDG had a sensitivity and specificity of 94.1% and 36.6% respectively in the derivation set and the validation set.

Recommendations for mandatory influenza vaccinations for health care personnel from AMDA's Infection Advisory Subcommittee.
Preventing influenza infections is a national health priority, particularly among geriatric and adults with frailty who reside in post-acute and long-term care (PALTC) settings. Older adults account for more than 70% of deaths from influenza, a reflection of decreased vaccine effectiveness in that age group. Annually vaccinating health care personnel (HCP) working with these patients against influenza is critical to reducing influenza morbidity and mortality among patients. In this paper, the authors discuss the recommendations for mandatory influenza vaccinations for health care personnel.

Tackling disparities in influenza vaccination in primary care: it takes a team.
This article discusses a study in the same issue by Maurer. Fiscella describes reasons involving influenza vaccination disparities and points out that the emergence of accountable care organizations creates opportunities for better integration of primary care and public health.

Seasonal influenza vaccination during pregnancy and the risks of preterm delivery and small for gestational age birth.
The researchers examined the associations between seasonal influenza vaccination during pregnancy and the risks of PTD and SGA among a multiyear retrospective cohort of pregnancies. With the exception of pre-term delivery (PTD) associated with the 2009–10 seasonal vaccine, they found no meaningful increases in PTD or small for gestational age risks associated with seasonal trivalent influenza vaccination during pregnancy.

Healthcare worker influenza vaccination in Oregon nursing homes: correlates of facility characteristics.
The authors identified nursing home (NH) characteristics that may be associated with employee influenza vaccination rates (EVRs). They concluded that, as NHs generally have low EVRs, it may be necessary to target low-performing facilities to achieve substantial improvements.

The association of meningococcal disease with influenza in the United States, 1989-2009.
The purpose of this paper is to quantify the fraction of meningococcal disease attributable to influenza. The authors found that, over 20 years, 12.8% of meningococcal disease can be attributable to influenza in the preceding weeks with H3N2 accounting for 5.2%, H1N1 4.3%, B 3.0%, and pH1N1 0.2%. They concluded that influenza vaccination could provide protection, particularly in young children where the meningococcal disease vaccine is not recommended or protective against the most common serogroup.

Health and economic benefits of early vaccination and nonpharmaceutical interventions for a human influenza A (H7N9) pandemic: a modeling study.
In order to determine how quickly vaccination should be completed to reduce infections, deaths, and health care costs in a severe influenza pandemic in a large metropolitan area, researchers used a dynamic transmission model. They found that vaccination in an influenza-A (H7N9) pandemic would need to be completed much faster than in the 2009 pandemic to substantially reduce morbidity, mortality, and health care costs.

School-located influenza vaccination: can collaborative efforts go the distance?
This commentary discusses school-located influenza vaccination during the school day and includes the survey results from Kempe et al., in the same issue. The authors conclude that increasing influenza vaccination rates will require vaccinating “outside the box,” utilizing a site in which school-aged youth already tend to congregate.

Demographic and clinical predictors of mortality from highly pathogenic avian influenza A (H5N1) virus infection: CART analysis of international cases.
The researchers for this international study sought to model individuals at highest risk of mortality from HPAI N5N1 virus infection in order to inform preventive and therapeutic interventions. They found that age, health expenditure, delay from symptom onset to hospitalization and country are significant predictors of mortality.
