  • DEVICES AND METHODS FOR ENHANCING IMMUNOGENICITY TO INTRADERMAL VACCINATION
    Publication number: 20190321234
    Abstract: Devices and methods that utilize an occlusive dressing in combination with a topical pharmaceutical agent to enhance vaccine efficacy are described. The occlusive dressing delivers a defined dose of a topical pharmaceutical agent that enhances immune system reactivity to a vaccine to the site of vaccination, and provides a barrier that maintains a layer of the topical pharmaceutical agent on the skin for a desired period to time while also providing a port through which an immunizing composition can be administered. In some embodiments the occlusive dressing includes a wound dressing for covering the injection site following vaccination.

  • Optimized collection of just-in-time statistics for database query optimization
    Patent number: 7917502
    Abstract: A system and method are provided for updating database statistics for use in generating query execution plans. A first query for a database is received, for example by a compiler, and the compiler accesses statistics associated with the first query for optimizing a query execution plan for the first query. The statistics may be accessed from a first cache. If the statistics retrieved from the first cache are determined to be stale, the system obtains updated statistics and may store them in a temporary cache. The stale statistics in the first cache are marked as invalid. Existing queries using the first cache may continue to use the first cache, while new queries may be provided with updated statistics.
