Vietnam818 participantsStarted 2019-03-19
Plain-language summary
The primary objective is to measure the effect of host human genetics on the resulting immunological responses and long-term protection following rotavirus immunization of a study population of infants in Ho Chi Minh City, Vietnam.
The secondary objectives are to assess the temporal immunological responses following rotavirus vaccination, and to investigate the role of maternally derived antibodies, and other factors that could potentially affect immunological responses following rotavirus vaccination. Also to assess infecting rotavirus genotypes in the vaccine failure cases.

* Currently registered residents of Districts 5 (where Hung Vuong Hospital is located) or 1, 6, 8, 10, or 11 (districts that are neighbouring district 5) in Ho Chi Minh city, with no specific intention of relocating in the next 12 months.
* Informed consent to be enrolled in the study and comply with study procedures, including host genetic studies.
Exclusion Criteria:
* Refusal of consent.
* Parent/ guardian under the age of 18.
* Premature (i.e. gestation period \<37 weeks).
* Infants who have already been immunized with either a rotavirus vaccine or the standard 2-month EPI vaccinations.
* History of hypersensitivity to any components of the vaccine or adverse vaccine event.
* History of intussusception or congenital malformation of the gastrointestinal tract in the child that is likely to predispose child to intussusception.
* History of severe combined immunodeficiency disease (SCID), acquired immune deficiency syndrome (AIDS) or Human immunodeficiency virus (HIV) positivity, or other known immunodeficiency syndromes that may place the child at risk during immunisation.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
