SERUM PNEUMOCOCCAL IgG LEVELS IN INFANTS OF MOTHERS VACCINATED WITH PNEUMOCOCCAL CONJUGATE VACCINE IN THE THIRD TRIMESTER |
Brief summary describing the background
and objectives of the trial
|
The study aim is to compare cord-blood levels of pneumococcal-specific Immunoglobulin G in new-borns whose mothers received the pneumococcal conjugate vaccine in the third trimester of pregnancy with matched controls whose mothers do not receive the vaccine and to determine what proportion of infants of vaccinated mothers have serum pneumococcal-specific IgG levels equaling or exceeding the W. H. O. - proposed immunological correlate of protection against pneumococcal disease at 6 weeks of life.
SPECIFIC OBJECTIVES
The objectives of the study are to:
Determine and compare the mean pneumococcal specific IgG levels in cord-blood of new-borns whose mothers were vaccinated with pneumococcal conjugate vaccine in the third trimester of pregnancy with new-borns whose mothers were vaccinated with placebo (controls).
Determine and compare the proportion of new-borns of vaccinated mothers and new-borns of controls with cord-blood geometric mean concentrations of pneumococcal-specific IgG equal to or exceeding 0.35 µg/ml (the immunologic correlate of protection for pneumococcal disease).
Determine the proportion of infants whose mothers were vaccinated with the pneumococcal conjugate vaccine in the third trimester of pregnancy with geometric mean concentrations of pneumococcal-specific IgG equal to or exceeding 0.35 µg/ml (the immunological correlate of protection for pneumococcal disease) at 6 weeks of life. |
