Filter by:The investigators propose a double-blind randomised placebo-controlled study in naturally occurring influenza virus infections in the community setting to compare the impact of a short course of clarithromycin versus placebo, on the clinical course, viral shedding, immunomodulation, and the antimicrobial resistance pattern of respiratory bacterial carriage of the patients.
The purpose of this study is to evaluate the safety, infectivity, and immunogenicity of two doses of the HPIV3/ΔHNF/EbovZ GP vaccine candidate when administered intranasally in healthy adults.
Non invasive methods are the only available methods to stage liver fibrosis during pregnancy. The safety of elastometry - ultrasound based - is obvious, as medical supervision of pregnancy is based on ultrasonography, both methods using same wavelengths. Therefore, this method is sometimes used in pregnant women with recent diagnosis of chronic viral hepatitis infection, whereas its validity in pregnant women has never been studied. This lack of data justifies our study.
Croup is an illness of young children that is caused by a virus. With this illness, the child has fever, cough, and hoarseness. Although the illness usually gets better in 2 to 4 days, some children may be admitted to the hospital and a few infants may require an intervention to help their breathing. This illness is most often caused by a virus called parainfluenza virus type 1, but it can be caused by other viruses. The experimental vaccine that is being investigated in this study is intended to try to prevent croup caused by parainfluenza virus type 1. Currently, there are no vaccines to prevent this virus, or medications available to treat the illness once infection has occurred. This research study is testing a new experimental live-virus vaccine that is given by placing liquid drops in the nose. The Sendai virus is very similar to the virus that causes croup, but it has never been found to cause illness in people. Previous studies in animals have shown that the vaccine provided protection against the croup virus, and did not cause illness. Many people have been exposed to the Sendai virus, but no one has been known to develop illness. Several healthy adults have been given the Sendai virus vaccine being studied, and they did not experience any serious side effects or illness.
