Abstract: A vaccine capable of protecting a recipient from infection caused by group B Streptococcus. The vaccine provides polysaccharide-protein moieties and contain (a) a group B Streptococcus polysaccharide conjugated to (b) a functional derivative of a group B Streptococcus C protein alpha antigen that retains the ability to elicit protective antibodies against group B Streptococcus. The vaccine may contain only one type of such polysaccharide-protein unit or may contain a mixture of more than one type of unit.

Abstract: A system and method for providing information to the operator of a land, water or airborne vehicle includes a wide-area message transmitter for transmitting messages to the vehicle and a vehicle-based receiver system. Each message includes identification information specifying a location (including a direction of travel) for which the message is intended. The receiver system on the vehicle computes its position and direction of travel and compares the position of the vehicle to the intended location indicated by each message. When a match is found, the receiver system provides the matching message to the operator of the vehicle. The messages are digitized voice messages. In a preferred embodiment, the vehicle-based receiver system calculates its position and direction of travel using either GPS or signals received from a local transmitter site.
