Criteria applicable at screening (before the birth of the infant):

  • Infants whose parents are below the legal consenting age of the country.
  • Infant's whose mother has multiple pregnancies.
  • Infant's whose mother has any confirmed or suspected immunosuppressive or immunodeficient condition (including positive infection with human immunodeficiency virus [HIV]), based on medical history, physical examination or positive test result.
  • Infant's whose mother is concurrently participating in another clinical study, at any time during the study period, in which the infant's mother has been or will be exposed to an investigational or a non-investigational vaccine/product.

Criteria applicable at enrolment (after the birth of the infant):

  • Child in care.
  • In case of multiple births.
  • Infants with any confirmed or suspected immunosuppressive or immunodeficient condition , based on medical history, physical examination or positive test result.

Arm Label

Second and third trimester Group

Arm Description

This study group will include infants whose mothers have received Boostrix during the second (21-27 weeks) and third trimester (above 28 weeks) of their pregnancy, as per routine practice.

Outcomes

Primary Outcome Measures

Number of seropositive subjects for anti-pertussis toxin (PT), anti-filamentous haemagglutinin (FHA) and anti-pertactin (PRN).
Seropositivity status was defined as anti-PT, anti-FHA and anti-PRN antibody concentrations ≥ 5 EL.U/mL.

Secondary Outcome Measures

Number of seropositive subjects for anti-PT, anti-FHA and anti-PRN.
Seropositivity status was defined as anti-PT, anti-FHA and anti-PRN antibody concentrations ≥ 5 EL.U/mL.
Anti-PT, anti-FHA and anti-PRN antibody concentrations.
Concentrations were expressed as geometric mean concentrations (GMCs) for the seropositivity cut-off of 5 EL.U/mL.

5. Study Description

Brief Summary
The purpose of the study is to support the recommendation of vaccination of all pregnant women in Colombia with Diptheria, tetanus and pertussis (dTpa) by studying the transfer of pertussis specific IgG antibodies from mother to the child.
Detailed Description
This study will assess the immunogenicity in infants (at birth and just prior to primary pertussis vaccination [i.e. diphtheria, tetanus and pertussis [DTP] vaccination] administered at 8 weeks of age), of a single Boostrix booster dose administered to their mothers during the second or third trimester as per routine practice in Bogota, Colombia.
