BACKGROUND Bioterrorism-related anthrax exposures occurred at the US Capitol in 2001. Exposed individuals received antibiotics and anthrax vaccine adsorbed immunization. METHODS A prospective longitudinal study of 124 subjects--stratified on the basis of spore exposure, nasopharyngeal culture results, and immunization status from inside and outside an(More)
Optimal protection against malaria may require induction of high levels of protective antibody and CD8(+) and CD4(+) T cell responses. In humans, malaria DNA vaccines elicit CD8(+) cytotoxic T cells (CTL) and IFNgamma responses as measured by short-term (ex vivo) ELISPOT assays, and recombinant proteins elicit antibodies and excellent T cell responses, but(More)
When introduced in the 1990s, immunization with DNA plasmids was considered potentially revolutionary for vaccine development, particularly for vaccines intended to induce protective CD8 T cell responses against multiple antigens. We conducted, in 1997-1998, the first clinical trial in healthy humans of a DNA vaccine, a single plasmid encoding Plasmodium(More)
BACKGROUND Vasoactivity has hampered progress of hemoglobin-based oxygen carriers (HBOCs) due to concern for adverse blood pressure responses and secondary complications. A recent formulation, highly polymerized HBOC-201 (Biopure, Cambridge, MA), has been found to be less vasoactive than prior less polymerized formulations, and to improve outcome in animal(More)
In this phase 1 clinical trial, healthy adult, malaria-naïve subjects were immunized with radiation-attenuated Plasmodium falciparum sporozoites (PfRAS) by mosquito bite and then underwent controlled human malaria infection (CHMI). The PfRAS model for immunization against malaria had previously induced >90 % sterile protection against homologous CHMI. This(More)
