School-based influenza immunization programs are increasingly recognized as a key component of community-based efforts to control annual influenza epidemics. Computer modeling suggests that immunizing 70% of schoolchildren could protect an entire community from the flu. Most of the school-based influenza immunization programs described in the literature have had support from industry or federal grants. This article describes a program that used only community resources to administer live, attenuated influenza vaccine supplied by the state health department. Beginning in 2006, the Alachua County Health Department and school system, working in collaboration with the University of Florida, began exploration of a non-mandatory community-wide school-based influenza immunization program, with the goal of achieving high levels of immunization of the ~22,000 public and private pre-K through grade 8 students in the county. In 2009-10 the program was repeated. This report describes the procedures developed to achieve the goal, the barriers that were encountered, and solutions to problems that occurred during the implementation of the program. Preliminary data suggest that the crude immunization rate in the schools was approximately 55% and that at least 10% more students were immunized by their health providers. At an operational level, it is possible to achieve high immunization rates if the stakeholders share a common vision and there is extensive community involvement.

BackgroundMany HIV databases and applications focus on a limited domain of HIV knowledge. Since even a “simple” organism like HIV represents a very complex system with many interacting elements, the fractured structure of existing databases and applications likely limits our ability to investigate and understand HIV. To facilitate research, therefore, we have built HIVToolbox, which integrates much of the knowledge about HIV proteins and presents the data in an interactive web application. HIVToolbox allows quick and convenient hypotheses generation, experiment interpretation, and potential new drug structure creation.MethodsHIVToolbox was built as a standard three-tier J2EE web application, consisting of 1) an underlying relational MySQL database, 2) a set of standard Java data access objects that pull data from the database, and 3) a set of dynamic web pages the user interacts with. HIV-1 data from external sources such as the Protein Data Bank, NCBI, Los Alamos, etc. was collected, curated, and stored in the HIVToolbox database. Additional data, such as homology and position statistics matrices, was generated from existing data. Since version 1, drug binding site and drug resistant mutation data has also been added.ResultsHIVToolbox was used to create several new hypotheses about HIV-1 integrase, including predicting the location of a CK2 phosphorylation site, which was later confirmed by experiment. A new version of HIVToolbox support display of the 3D locations of drug resistant mutations on surface plots of HIV proteins and the drug binding sites for structures of complexes of HIV proteins with drugs.ConclusionHIVToolbox is an open-access web application that allows virologists and structural biologists to access detailed information about HIV-1 proteins, such as sequence, structure, functional sites and relationships, homology, drug binding sites, and drug resistant mutations, and to immediately see the relationships between any or all of them.
