|Condition or disease||Intervention/treatment||Phase|
|Healthy Volunteers Norovirus||Biological: NoV Vaccine||Phase 2|
The drug being tested in this study is called NoV vaccine. NoV vaccine is being tested for protection against acute gastroenteritis (AGE) due to norovirus.
The study will enroll maximum of 575 participants. Participants who previously received NoV vaccine in studies NOR-107, NOR-210 and NOR-204 will be enrolled. Participants from study NOR-107 will enter the study at the time of their 3rd year post-primary vaccination, and from studies NOR-210 and NOR-204, at their 2nd year post-primary vaccination. The duration of participation in the study will be different for each participant.
This multi-center trial will be conducted in Belgium and the United States. The overall time to participate in this study is maximum 5 years after primary NoV vaccination. Participants will have a maximum of 4 visits over 3 years.

Experimental: NoV Vaccine
Participants who previously received NoV vaccine adjuvanted with aluminum as aluminum hydroxide or with monophosphoryl lipid A (MPL), injection, intramuscularly as planned in studies NOR-107, NOR-210 and NOR-204 will be assessed over 5 years post-primary vaccination. Vaccine formulations according to the parent trials: NOR-107, 210 and 204.
Biological: NoV Vaccine
No NoV vaccine injection administered.
