Arbovirus infection

This study tests whether giving patients donor-derived immune cells (VSTs) on a regular schedule can prevent dangerous viral infections after a stem cell transplant. 180 participants will be randomly assigned to receive VSTs either on a fixed schedule or only when a virus is dete…

This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boos…

This study is testing a new blood test called ARBOspot that looks for immune cell responses to viruses spread by mosquitoes and ticks. Researchers will enroll 500 adults in Italy with suspected arbovirus infection. The goal is to see if this test can help diagnose infections that…

This study aims to collect samples and medical information from people of all ages who have or have been exposed to viral infections, including COVID-19 and herpes. Researchers want to understand how viruses affect healthy individuals versus those with weakened immune systems. Pa…

This study aims to understand how viruses spread in Fiji by tracking about 900 people over three years. Participants will provide blood samples and answer questions about their health. The goal is to learn about immunity and transmission to help prepare for future outbreaks.
