Inclusion criteria

  1. Is male or female aged two months (50 to 70 days inclusive) on the day of the first dose of study vaccine.
  2. Is born at full term of pregnancy (≥37 weeks of gestation) with a birth weight of ≥2.5 kg.

Exclusion criteria

Exclusion Criteria:

Medical conditions:

  1. Has a history of diphtheria, tetanus, pertussis, poliovirus, Hep B, or Hib infection.
  2. Has a known SARS-CoV-2 infection at Screening.
  3. Was born to a mother with a known history of Hep B infection based on seropositivity.
  4. Was born to a mother with a known history of infection based on HIV antibody seropositivity.
  5. Had a recent febrile illness, defined as axillary temperature ≥38.0℃ [≥100.4℉] occurring at or within 72 hours prior to receipt of study vaccine.

    Prior/concomitant therapy:

  6. Has previously received vaccination against diphtheria, tetanus, pertussis, poliovirus, and/or Hib infections since birth.
  7. Has received or is expected to receive agents or other immune-modifying drugs during the conduct of the study.
  8. Meets one or more of the following systemic exclusion criteria:

    1. Has received systemic corticosteroids (equivalent of ≥0.5 mg/kg total daily dose of prednisone) for ≥14 consecutive days and has not completed treatment at least 30 days prior to Screening.
    2. Is expected to require any systemic corticosteroids during conduct of the study.

    Note: Topical, ophthalmic, and inhaled steroids are permitted at the discretion of the Investigator.

  9. Has received any non-study vaccine within 30 days before the first dose of study vaccine or is scheduled to receive any other vaccine within one month after the third dose of study vaccine.

Exception: Vaccines against BCG and Hep B at birth, rotavirus, MMR, and PCV if received according to the routine immunization schedule, and inactivated influenza vaccine, are allowed.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Seroprotection/vaccine-response rate

    * Proportion of subjects achieving seroprotection to each antigenic components * Proportion of subjects with vaccine response for pertussis antigens

    Time frame: 1 month after the third dose primary series

Secondary outcomes

  1. Geometric mean concentration (GMC) or Geometric mean titer (GMT)

    GMC or GMT and their ratio of all types of antibodies

    Time frame: 1 month after the third dose primary series

  2. Seroconversion rate

    Proportion of subjects achieving seroconversion to pertussis and poliovirus

    Time frame: 1 month after the third dose primary series

  3. Long-term seroprotection rate

    Proportion of subjects with seroconversion for diphtheria, tetanus, and Hib antigens

    Time frame: 1 month after the third dose primary series

  4. Solicited adverse event

    Expected local or systemic side effects after vaccination

    Time frame: 7 days after each vaccination

  5. Unsolicited adverse event

    Any AEs other than solicited AEs

    Time frame: 1 month after each vaccinations

  6. Immediate reactions after vaccination

    Any AEs that occur within 30 minutes after the study vaccine administration

    Time frame: 30 minutes after each vaccination
