At the time of the outbreak of the pandemic of New Influenza A (H1N1) pandemic influenza vaccines became available via an accelerated registration procedure. In 2005 large stocks of the neuraminidase inhibitor oseltamivir were built up in the Netherlands and other western countries. ⋯ There now have been reports of rare and serious side effects. The first reports on the severity of the pandemic in Australia and New Zealand indicated a mild course.

Determinants of non-vaccination against pandemic 2009 H1N1 influenza in pregnant women: a prospective cohort study.
In October 2009, the French government organized a national-wide, free of charge vaccination campaign against pandemic H1N1 influenza virus, especially targeting pregnant women, a high risk group for severe illness. The study objective was to evaluate pandemic flu vaccine uptake and factors associated with non-vaccination in a population of pregnant women. ⋯ In this cohort of pregnant women, vaccine coverage against pandemic 2009 A/H1N1 flu was low, particularly in immigrant women and those having a low socio-economic status. To improve its effectiveness, future vaccination campaign for pregnant women should be more specifically tailored for these populations.

To assess the impact of the 2009 A/H1N1 influenza pandemic in England during the two waves of activity up to end of February 2010 by estimating the probabilities of cases leading to severe events and the proportion of the population infected. ⋯ This study suggests a mild pandemic, characterised by case and infection severity ratios increasing between waves. Results suggest low ascertainment rates, highlighting the importance of systems enabling early robust estimation of severity, to inform optimal public health responses, particularly in light of the apparent resurgence of the 2009 A/H1N1 strain in the 2010-11 influenza season.

A model survey for assessing 2009 pandemic influenza A (H1N1) virus disease burden in the workplace.
Emergence of 2009 pandemic influenza A (H1N1) (pH1N1) virus in 2009 raised concern about the potential impact of widespread or severe disease on the nation's workforce. The Centers for Disease Control and Prevention recommended that employers develop flexible pandemic response plans. We used the Behavioral Risk Factor Surveillance System's influenza module as a model for a brief workplace survey to ascertain the influenza-like illness (ILI) burden on epidemiology staff in Centers for Disease Control and Prevention Emergency Operations Center. ⋯ The 10 respondent ILI cases missed 24 total work days, although none sought medical care. Eleven (14%) of 77 household contacts also had ILI, but no ILI case was hospitalized. This survey enabled us to rapidly obtain information about our workforce ILI burden and evaluate the potential need for additional resources because of employee absence.

Comparative StudyDoes triage to critical care during a pandemic necessarily result in more survivors?
The 2009 H1N1 pandemic reinforced the need for a planned response to increased demand for critical care. Triage protocols have been proposed incorporating the exclusion of specified subgroups of patients from critical care. There have been no studies that explore the theoretical underpinning of triage at referral, and it is not clear under what circumstances triage would confer the intended benefits. We sought to explore the mechanisms whereby triage could lead to fewer deaths across a critical care population in the context of a pandemic. ⋯ The impact of triage is dependent on the level of demand and on the scale of achievable differences between included and excluded groups in terms of anticipated length of stay and critical care survival. It cannot be assumed that triage can or will result in fewer deaths. It should be remembered that there are considerations other than population-level short-term survival when determining the objectives of triage and its ethical implementation.
