Varicella zoster infection

This early-stage trial is testing a new mRNA vaccine called ABO1108 to prevent shingles in adults aged 40 and above. Around 180 healthy volunteers will receive two shots of either the new vaccine at different doses, a placebo, or the existing Shingrix vaccine. The main goal is to…

This study tests a new mRNA vaccine called ABO1108 to see if it can prevent shingles in adults aged 40 and above. About 300 healthy volunteers will receive two shots, two months apart, and be compared to a placebo group. The goal is to measure the immune response and check for sa…

This study tests a new shingles vaccine called LYB004 in 840 adults aged 40 and older in China. Participants receive one of four different doses of the vaccine or a placebo. The goal is to see how well the vaccine triggers an immune response and whether it is safe.

This study looks at whether the shingles vaccine is safe and works well in young adults (19 and older) who have had a solid organ transplant. About 80 participants will get two doses of the vaccine and be monitored for side effects and immune response. The goal is to help protect…

This study looks at how the immune system of kidney transplant patients responds to the shingles vaccine and to natural shingles infection. Researchers will track antibody and T-cell levels over time in patients who have had a transplant or are on the waiting list. The goal is to…

This study looks at how the immune system's T cells respond to two common herpesviruses—cytomegalovirus (CMV) and varicella-zoster virus (VZV)—in people who have had a liver transplant. Because transplant recipients take drugs that suppress their immune system to prevent organ re…

This study looks back at medical records of 50 adults who had a shingles virus infection in their brain or spinal cord. Researchers want to find out what makes some people more likely to get these serious infections and what leads to long-term problems like memory loss or seizure…

This study looks at how the Shingrix vaccine, which protects against shingles, affects immune cells in the skin and blood. Researchers will give the vaccine to 50 healthy adults in two age groups: 30-40 years old and 70 years or older. They will measure specific antibodies and T-…
