Randomized Controlled Trial Multicenter Study Comparative Study
An observer-blind, randomized, multi-center trial assessing long-term safety and immunogenicity of AS03-adjuvanted or unadjuvanted H1N1/2009 influenza vaccines in children 10-17 years of age.
Vaccination is an effective strategy to prevent influenza. This observer-blind, randomized study in children 10-17 years of age assessed whether the hemagglutination inhibition (HI) antibody responses elicited by H1N1/2009 vaccines adjuvanted with AS03 (an adjuvant system containing α-tocopherol and squalene in an oil-in-water emulsion) or without adjuvant, met the European regulatory immunogenicity criteria at Days 21 and 182. ⋯ All study vaccines elicited HI antibody responses that persisted at purported protective levels through six months after vaccination and fulfilled the European regulatory criteria.

Observational Study
Access to the NHS by telephone and Internet during an influenza pandemic: an observational study.
To examine use of a novel telephone and Internet service-the National Pandemic Flu Service (NPFS)-by the population of England during the 2009-2010 influenza pandemic. ⋯ This innovative healthcare service operated at large scale and achieved its aim of relieving considerable pressure from mainstream health services, while providing appropriate initial assessment and management for patients. This offers proof-of-concept for such a service that, with further refinement, England can use in future pandemics. Other countries may wish to adopt a similar system as part of their pandemic emergency planning.

Mobilising "vulnerability" in the public health response to pandemic influenza.
Analysis of public health's growing interest in "vulnerability" has largely focused on health policy, with little interrogation of how vulnerability is being actively appropriated, countered, ignored or reworked by the publics whose health such policy is designed to protect. Once the assemblage of public health is understood as comprised of different forms of expertise and actors, including publics, addressing this gap matters. We examine the use of vulnerability in the specific context of pandemic influenza preparedness. ⋯ Vulnerability is variously used in plans as a way to identify groups at particular risk of infection because of pre-existing clinical conditions, and as a free-floating social category that could apply to a broad range of people potentially involved in the social disruption a pandemic might entail. Our interview and focus group data indicate that healthy people rework the free-floating extension of vulnerability, and that people designated vulnerable encounter an absence of any collective responsibility for the threat of pandemic influenza. Our analysis suggests that vulnerability's mobilisation in pandemic preparedness limits the connection between public health governance and its publics: here, the openness and unpredictability of people's collective agency is something to be tightly controlled by a government concerned with protecting people from themselves.

Historical Article
Second-pandemic strain of Vibrio cholerae from the Philadelphia cholera outbreak of 1849.
In the 19th century, there were several major cholera pandemics in the Indian subcontinent, Europe, and North America. The causes of these outbreaks and the genomic strain identities remain a mystery. ⋯ This O1 biotype strain has 95 to 97% similarity with the classical O395 genome, differing by 203 single-nucleotide polymorphisms (SNPs), lacking three genomic islands, and probably having one or more tandem cholera toxin prophage (CTX) arrays, which potentially affected its virulence. This result highlights archived medical remains as a potential resource for investigations into the genomic origins of past pandemics.
