New 6-in-1 shot for babies shows promise in thai trial
NCT ID NCT04429295
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new combination vaccine called Shan6™, which protects against six diseases (diphtheria, tetanus, whooping cough, hepatitis B, Hib, and polio) in healthy infants and toddlers in Thailand. The trial involved 460 participants and compared Shan6™ to a similar 5-in-1 vaccine given with separate polio shots. The goal was to see if Shan6™ works just as well and is safe when given alongside routine childhood vaccines.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Shan6™ (6-in-1 vaccine against diphtheria, tetanus, pertussis, hepatitis B, Hib, and polio)
- What this could lead to
- If successful, this could provide a simpler 6-in-1 vaccine option for infants, reducing the number of shots needed.
- What could go wrong
- This is a completed Phase 3 trial, so results are already in. The main risk is that the vaccine may not be as effective or safe as the current separate vaccines, but the study aims to show it is non-inferior.

Inclusion criteria : * Aged ≥ 2 months (age range of 8 weeks \<12 weeks) on the day of the first vaccination * Born at full term of pregnancy (≥ 37 weeks) and with a birth weight ≥ 2.5 kg or medically stable prematurely born infants (born after a gestational period of 27-36 weeks) * Infants who have received the birth dose of Bacille Calmette-Guérin vaccine (BCG) at least 4 weeks before the first trial vaccination * Participant and parent(s)/legally acceptable representative(s) are able to attend all scheduled visits and comply with all study procedures Exclusion criteria: * Participation at the time of study enrollment (or in the 4 weeks preceding the first trial vaccination) or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure * Receipt of any vaccine in the 4 weeks preceding the first trial vaccination or planned receipt of any vaccine within the period of 4 weeks before to 4 weeks after each trial vaccination, except for oral polio vaccine (OPV) and influenza vaccination. OPV may be received any time during the study while influenza vaccination may be received at a gap of at least 2 weeks before or 2 weeks after any study vaccination. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines * Previous vaccination against diphtheria, tetanus, pertussis, hepatitis B (except the dose of Hep B vaccine given at birth or at least 4 weeks before the first trial vaccination), Haemophilus influenzae type b, poliomyelitis (except OPV), rotavirus, and Streptococcus pneumoniae with either the trial vaccines or another vaccine * Receipt of immune globulins, blood or blood-derived products since birth * Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy since birth; or long-term systemic corticosteroid therapy (prednisone or equivalent at ≥ 0.5 mg/kg/day for more than 2 consecutive weeks since birth) * Known personal or maternal history of Human Immunodeficiency Virus (HIV), hepatitis B (HBsAg positive), or hepatitis C (hepatitis C virus \[HCV\] ribonucleic acid \[RNA\] positive) * Individuals with blood dyscrasias, leukemia, lymphoma of any type, or other malignant neoplasms affecting the bone marrow or lymphatic systems * History of diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, Haemophilus influenzae type b, rotavirus, or pneumococcal infection(s) confirmed either clinically, serologically, or microbiologically * History of any neurologic disorders, including encephalopathy, seizures (febrile and non-febrile) and progressive neurologic disorders * History of intussusception * In an emergency setting, or hospitalized * Known systemic hypersensitivity to any of the vaccine components or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances * Thrombocytopenia, as reported by the parent/legally acceptable representative, contraindicating intramuscular vaccination in the Investigator's opinion * Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination in the Investigator's opinion * Chronic illness that, in the Investigator's opinion, is at a stage where it might interfere with trial conduct or completion * Any condition which, in the Investigator's opinion, might interfere with the evaluation of the study objectives * Moderate or severe acute illness/infection (according to the Investigator's judgment) on the day of vaccination or febrile illness (axillary temperature ≥ 38.0 C). A prospective participant should not be included in the study until the condition has resolved or the febrile event has subsided * Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw * Identified as a natural or adopted child of the Investigator, relatives or employee with direct involvement in the proposed study The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
