According to the researchers, this systematic assessment should include a cerebrospinal fluid culture, a blood culture, a urine culture, and a determination of the quantity (titration) of the circulating antigen of Cryptococcus. ...

NIAID DNA vaccine for H5N1 avian influenza enters human trial

...uman-to-human transmission have been reported. The severity of disease and the potential for human-to-human spread has provided a major incentive to accelerate developing a human vaccine for avian influenza. With the spread of avian influenza virus, new strains have emerged, including clade II viruses in I...

...jects. After a physical examination that rated the severity of symptoms ranging from pain to range of motion, participants were given blood tests for evidence of biomarkers. "The blood tests revealed significant levels of several types of inflammatory mediators ?biomarkers ?which signaled an underlying pr...

... individuals. According to the researchers, the severity of such a health crisis could be reduced if programs were to provide several years of free vaccinations to individuals who pay for only one year. Interestingly, however, some incentive programs could have the opposite effect. Providing free vaccinati...
