A Phase 3 Study to Evaluate the Immunogenicity and Safety of Walvax's PCV13-TT as Compared to Pfizer's PCV13

Plain-language summary
The goal of this clinical trial is to evaluate the immunogenicity and safety of a novel 13-valent pneumococcal polysaccharide conjugate vaccine (PCV13-TT) as compared to Pfizer's 13-valent pneumococcal conjugate vaccine (PCV13) when co-administered with local EPI Vaccines at 2, 4, and 12-15 months of age, to healthy infants in Indonesia. This study aims to demonstrate the non-inferiority of the serotype-specific immune responses elicited by the novel PCV13-TT as compared to PCV13 one month after the booster dose.

Inclusion criteria
. Healthy infants based on medical history and clinical assessment.
. Age of 6-8 weeks at enrolment. Infants will be eligible since the day they reach 6 weeks of age and until 8 weeks of age included.
. Body weight at enrollment ≥3.5 kg.
. Infant's parent(s) or legal guardian(s) must be able and willing to provide voluntary written/thumb-printed informed consent for the infant to participate in the study.
. Infant's parent(s) or legal guardian(s) must be able to comprehend and comply with study requirements and procedures and must be willing and able to return or make themselves available for all scheduled follow-up visits.
. Infant's parents must have a readily identifiable place of residence in the study area, be available for the duration of trial participation, and have means of telephone contact.
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.
What they're measuring
1
Immunogenicity and non-inferiority as measured by serotype-specific IgG
Timeframe: 1 month after the booster dose
2
Immunogenicity and non-inferiority as measured by serotype-specific IgG GMC
. Use of any investigational medicinal product prior to randomization or planned use of such a product during the period of study participation.
. History of S. pneumoniae infection as confirmed by medical enquiry or as confirmed by laboratory testing if available.
. Participant has fever (axillary temperature ≥ 37.5℃) within 24 hours prior to the 1st dose of vaccination; (If the subject does not meet the criteria, the visit may be rescheduled when the criteria are met.)
. The infant who are children in care, preterm and low-birth-weight(Preterm infants have a gestational age below 37 weeks at birth and low-birth-weight infants have a birth weight below 2.5 kg).
. History of allergic disease or history of a serious reaction to any prior vaccination or known hypersensitivity to any component of the 2 study vaccines. This includes all components of the EPI vaccines.
