Chickenpox

This study tests a new chickenpox vaccine called NBP608 in about 780 children aged 1 to 12 years. The vaccine is compared to licensed vaccines to see how well it triggers immunity and if it is safe. Children receive one or two shots, and researchers monitor their immune response …

Researchers are testing an experimental mRNA vaccine called ABO1108 to see whether it can prevent herpes zoster, the painful rash also known as shingles. The trial enrolls adults aged 40 and older, including people whose long-term conditions are stable. Participants receive two i…

This study tests a new vaccine that protects against measles, mumps, rubella, and chickenpox (MMRV) in healthy children aged 15 months to 6 years. It compares the new vaccine to an already approved one (ProQuad) to see if it works as well and is safe. About 1,200 children will re…

This study tests a new chickenpox vaccine in 600 healthy toddlers aged 12-15 months. The children receive two doses, and the new vaccine is compared to the current standard, Varivax. The goal is to see if the new vaccine produces a strong immune response and is safe.

This study tests a new chickenpox vaccine in 750 healthy children aged 12-15 months. Researchers will compare its safety to the existing Varivax vaccine. The goal is to see if the new vaccine causes similar side effects like injection site pain, fever, or rash.

This study tests a new chickenpox vaccine given as a muscle injection in healthy children aged 12 to 15 months. It compares the immune response and safety of this vaccine to the standard shot given under the skin. The study also looks at combining it with the MMR vaccine. About 9…

This study tests a new chickenpox vaccine in healthy children aged 12 to 15 months who have never had chickenpox or the vaccine. Researchers want to see if the new vaccine works as well as the approved Varivax vaccine and if different batches of the new vaccine produce consistent…

This study tests a new chickenpox vaccine called MG1111 in healthy children aged 1 to 12 years. About 474 kids will receive either the new vaccine or the current one (Varivax) to compare safety and immune response. Participants will be followed for 42 days after each dose, and up…

This study looks at how well a second dose of the chickenpox vaccine works and if it is safe for healthy children aged 15 months to 12 years. About 300 children who already had one dose at 12 months old will get a second dose made by Sinovac. Researchers will measure antibody lev…

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 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 will test 10,000 people in Cambodia for 57 different infectious diseases, including dengue, flu, and malaria. Researchers want to understand how these diseases spread and who is at risk. The goal is to give local health authorities the information they need to create b…
