Experiment/Payload Overview
Brief Summary
National Lab Pathfinder - Vaccine - 3 (NLP-Vaccine-3) is a commercial payload serving as a pathfinder for the use of the International Space Station (ISS) as a National Laboratory after ISS assembly is complete. It contains several different pathogenic (disease causing) organisms. This research is investigating the use of space flight to develop potential vaccines for the prevention of different infections caused by these pathogens on Earth and in microgravity.

Experiment/Payload Description
Research Summary
- Many pathogenic bacterial strains are the most common cause of food poisoning world-wide, and a major cause of childhood death worldwide. In the US, untoward effects caused by these pathogenic organisms cost billions of dollars annually. There is currently no vaccine available for common forms of pathogenic organisms which cause gastroenteritis illnesses in millions of people worldwide every year.
- For National Lab Pathfinder - Vaccine - 3 (NLP-Vaccine-3), a unique and simple model of infection will be used. This work will be follow-on work to research conducted on STS-123, STS-124 and STS-126 in support of previous NLP investigations. Several other proprietary pathogens will be grown in space under conditions known to effect bacterial potency, also referred to as virulence (infection potential). This approach will take advantage of knowledge gained in previous space flight studies of these organisms. Once the experiment is completed on orbit and returned to Earth, analysis of virulence will be completed by the investigator.
Description
The 2005 NASA Authorization Act designated a portion of the International Space Station (ISS) as a National Laboratory. To fulfill that mandate, NASA is providing an opportunity for non-governmental entities to conduct research and development and potentially industrial processing on board the ISS. These opportunities aboard the ISS are considered National Lab Pathfinder (NLP) missions. These NLP missions will launch to the ISS on each available Space Shuttle mission, until the Shuttle is retired in approximately 2010. This research, National Lab Pathfinder - Vaccine - 3 (NLP-Vaccine-3) is the next experiment in a series of National Lab Pathfinder missions sponsored by SPACEHAB, Incorporated and its subsidiary BioSpace Technologies.
NLP-Vaccine-3 will take advantage of knowledge gained in previous space flight studies of virulence and vaccine development. Once the experiments are completed on orbit and returned to Earth, analysis of virulence will be completed by the investigator.

Applications
Space Applications
Results from this experiment may help scientists more clearly understand measures that should be taken to reduce the risk of infection and contraction of different diseases while in space.
Earth Applications
There is currently no vaccine available for the strains of pathogenic strains of bacteria which cause diarrhea for public use in humans. This research may help develop vaccines against this life threatening organism.

Operations
Operational Requirements
This payload will be conducted under ambient temperature conditions and will not require image or data download.
Operational Protocols
The research will be contained in the Fluid Processing Apparatus (FPA). In order to activate the samples, the crew will turn a hand crank that has been inserted onto the top of the GAP A300 which contains the FPAs. Once the samples have been activated for a predetermined length of time, the crew will again turn the hand crank on top of the GAP A300s to terminate the experiment. The terminated samples will be returned to Earth via the Space Shuttle.
