Norovirus Vaccine Clinical Trials
Norovirus is a leading cause of sudden stomach illness, and researchers are working to develop new ways to help prevent it. 3A Research is conducting a Norovirus Vaccine Clinical Trial evaluating an investigational mRNA vaccine in adults aged 18 and older. Enrollment for this study is currently closed while the study is ongoing — explore what the research involves, and contact us to learn about other studies you may qualify for.

Norovirus Vaccine Clinical Trials
Understanding the Condition
Norovirus is a highly contagious virus and a common cause of acute gastroenteritis — inflammation of the stomach and intestines. It can cause symptoms such as vomiting, diarrhea, nausea, and stomach cramps, and it spreads easily from person to person and through contaminated food, water, and surfaces.
Most people recover within a few days, but norovirus can lead to dehydration, particularly in older adults and those with other health conditions. There is currently no widely available vaccine to prevent it, which is why research is important.
By taking part in a Norovirus Vaccine Research Study in Texas, participants help researchers explore investigational approaches to preventing norovirus illness.
Important Information About Participation
Participation in Norovirus Vaccine Clinical Trials is voluntary. Investigational vaccines are studied for safety and effectiveness, but there is no guarantee of personal benefit. Studies are conducted under strict regulatory guidelines. Consult with your healthcare provider before enrolling in this or any other clinical research study.

About the Norovirus Vaccine Study
This Phase 3 study is evaluating the safety and efficacy of an investigational mRNA vaccine intended to help prevent acute gastroenteritis caused by norovirus, in adults aged 18 and older. It is not yet known whether the investigational vaccine is safe or effective for this use.
Participants attend study visits where the study team monitors their health and gathers information throughout the study. Enrollment for this study is currently closed while the study is ongoing.
What to Expect in Norovirus Vaccine Clinical Trials
This study is currently closed to enrollment while it is ongoing. Clinical trials give participants access to study-related care and monitoring under expert medical supervision. Contact us to learn about other studies at 3A Research that may be accepting participants.
Frequently Asked Questions
This study is closed to enrollment, but it is ongoing — participants already enrolled continue to attend their study visits. Contact us to learn about other studies at 3A Research that may be accepting participants.
Norovirus is a highly contagious virus that causes acute gastroenteritis, with symptoms such as vomiting, diarrhea, nausea, and stomach cramps. It is a very common cause of sudden stomach illness.
Norovirus spreads easily from person to person and through contaminated food, water, and surfaces. Thorough handwashing and careful food handling are among the everyday steps used to help reduce its spread.
An mRNA vaccine gives the body instructions to make a harmless piece of protein that helps the immune system recognize and respond to a virus. The vaccine in this study is investigational, meaning it is still being evaluated.
