Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Young infants are most vulnerable to severe disease and even death when infected with Bordetella pertussis. The current vaccines and vaccination programs do not guarantee protection of neonates from this disease. Maternal acquired pertussis-specific antibodies show low concentrations with short persistence in newborns creating a susceptibility gap for infection between birth and the first vaccinations. A possible strategy to protect infants from birth is pertussis vaccination during pregnancy, which will increase the amount of passively transferred maternal antibodies.

However, little is known regarding the effect of high titers of maternal antibodies on the infants immune responses to different pertussis vaccines (whole cell versus acellular). Humoral immune responses will be assessed in infants receiving whole cell versus infants receiving acellular pertussis vaccines. Functionality of the antibodies will also be analyzed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A

Women will be vaccinated with an acellular pertussis containing vaccine (Boostrix) between 27 and 36 weeks of gestation. Children born from these mothers will be vaccinated according to the official recommendations in Thailand at 2, 4, 6 and 18 months with a hexavalent acellular pertussis containing vaccine (Infanrix hexa).

Group Type EXPERIMENTAL

Boostrix

Intervention Type BIOLOGICAL

Pregnant women will be vaccinated with an acellular pertussis containing vaccine between 27 and 36 weeks of gestation.

Infanrix hexa

Intervention Type BIOLOGICAL

Children from group A will be vaccinated with an acellular pertussis containing vaccine according to the official recommendations in Thailand at 2, 4, 6 and 18 months.

Group B

Women will be vaccinated with an acellular pertussis containing vaccine (Boostrix) between 27 and 36 weeks of gestation. Children born from these mothers will be vaccinated according to the official recommendations in Thailand at 2, 4, 6 and 18 months with a pentavalent whole cell pertussis containing vaccine (Quinvaxem). OPV (oral poliovirus vaccine) will also be administered at 2, 4, 6 and 18 months.

* Intend to be available for follow-up visits and phone call through 19 months postpartum
* Willing to have infant immunized with a pertussis containing vaccine at 2, 4, 6 months and 18 months of age according to EPI (Expanded Programme of Immunization) and receiving (randomized) either acellular pertussis (aP) (study vaccine) or a whole cell pertussis (wP) vaccine. Consent for participation of the child is needed by both married parents or by a single unmarried other.

* Receipt of tetanus-diphtheria toxoid immunization within the past 1 month Receipt of an pertussis containing vaccine (Tdap) in the last 5 years
* Receipt of a vaccine, blood product (excluding Rhogam) within the 4 weeks prior to injection through 4 weeks following injection and IVIG (Intravenous Immunoglobulins) within 12 weeks period. One month interval should be respected with another vaccine (except influenza) in orde to evaluate Adverse events following one or both vaccines (fever, local symptoms)
* Receipt of an experimental drug during pregnancy
* Anything in the opinion of the investigator that would prevent women from completing the study or put the woman at risk
