Chickenpox vaccine protection study for children with close contact
Treatments studied
Part of Infections clinical trials.
This study looks at how well the varicella (chickenpox) vaccine protects people who have been in close contact with someone who has chickenpox. It may help find better ways to prevent chickenpox in children.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 1 to 12 years old
- You are a sibling, child, deskmate, or roommate of someone who has chickenpox (called the 'indicator varicella case')
- You had close contact with that person for at least 2 days during the 5 days before their rash started to 2 days after
- You have either never had a chickenpox vaccine, or you have only had a Sinovac varicella vaccine (last dose more than 30 days ago)
- You do not currently have a fever over 37.0°C or a rash on your head, body, or limbs
- You do not have a weakened immune system (like from HIV, cancer treatment, or long-term steroids)

Other trials that look related to this one.
This trial follows people who previously took a chickenpox (varicella) vaccine to see how long their immune protection lasts. It may help explain who stays protected over time and for how long.
This trial tests how safe and how well a live, weakened chickenpox (varicella) vaccine works in healthy people age 13 and older. If you qualify, you may receive the study vaccine and be monitored for side effects and immune response.
This study follows up people who were in a previous phase 3 chickenpox vaccine trial. It checks how long protection from a booster dose lasts, by taking a blood sample.
This study gives a second chickenpox vaccine dose to healthy children who were vaccinated once before. It mainly checks safety and measures the body’s immune response to see how well the second dose works.
This trial tests a chickenpox vaccine in healthy children ages 1 to 12 to see how well it works and if it's safe. If your child has never had chickenpox or the vaccine, or had one dose at least 3 months ago, they may be able to join.
This trial tests a live chickenpox vaccine given at the same time as the MMR or DTaP shot for children ages 18 to 24 months. It may help protect your child from chickenpox while keeping their regular vaccine schedule on track.
