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.

Identifying the interaction between influenza and pneumococcal pneumonia using incidence data.
The authors integrated weekly incidence reports and a mechanistic transmission model within a likelihood-based inference framework to characterize the nature, timing, and magnitude of the interaction between influenza and pneumococcal pneumonia. They found support for a strong but short-lived interaction, with influenza infection increasing susceptibility to pneumococcal pneumonia ~100-fold. They inferred modest population-level impacts arising from strong processes at the level of an individual.

Microsimulation of financial impact of demand surge on hospitals: the H1N1 influenza pandemic of fall 2009.
Microsimulation was used to assess the financial impact on hospitals of a surge in influenza admissions in advance of the H1N1 pandemic in the fall of 2009 with the goal of estimating net income and losses of a response of filling unused hospital bed capacity proportionately and postponing elective admissions. They concluded that aggregate and distributional results did not suggest that a policy of promising additional financial compensation to hospitals in anticipation of the surge in flu cases was necessary.

Impact of the fall 2009 influenza A(H1N1)pdm09 pandemic on US hospitals.
The authors investigated the impact of the 2009 influenza A(H1N1)pdm09 pandemic on US hospitals. They found that the fall 2009 pandemic period substantially impacted US hospitals, mostly through increased emergency department visits. Furhter, for a small proportion of hospitals that experienced a high surge in inpatient admissions, increased mortality from selected clinical conditions was associated with both prepandemic outcomes and surge, highlighting the linkage between daily hospital operations and disaster preparedness.
