Main: To assess the effect of an early extra measles immunization between 6and 12 months of age on the development of humoral and cell-mediatedimmunity against measles following routine MMR immunization at 14months of age.Secundary:Determine effect…
Primary objective;Confirm superiority of IgG antibody levels against pertussis toxin (Ptx), present in the acellular vaccines, in infants at the age of 3 months of mothers having received a pertussis vaccine during pregnancy versus infants of…
This study aims to identify global and local determinants of HPV vaccine acceptability, HPV vaccine uptake and compliance as well as identify logistics and programmatic issues in each country to offer the HPV vaccine, as a potential cervical cancer…
The assessment of the duration of the cellular immunity to Bordetella pertussis after an extra ACV booster and the relationship between the memory B- cells and antibody responses. The methods used in the study are:B- and T- cell memory responses and…
To assess the effect of alternative and reduced doses pneumococcal vaccination schedules using the 13-valent pneumococcal conjugate vaccine (PCV13, Wyeth) on the development of antibody titers directed against the different serotypes of pneumococci…

Investigate the effects of aP booster vaccination in children, young adults and elderly on the (long-term) immune response to B. pertussis in three European countries with a different epidemiological background and primary vaccination schedule for…
*Premature infants and maternal pertussis immunization. Is second trimester vaccination beneficial?*
Our primary objective is to evaluate non-inferiority of anti-Pertussis Toxin (PT) IgG in term infants at 2m of age born of mothers having received a pertussis vaccine between 20-24w Gestational Age (GA) compared to a reference anti-PT IgG at 2m of…
The main objective of this trial will be to get a better insight in the influence of age and age-related changes by internal and external factors on vaccine-induced immune responses and gain knowledge on the trajectory of immune decline in older…
The aim of this study is to investigate whether the transfer of antibodies from mother to infant is less effective in infants with intrauterine growth restriction (FGR) compared to term-born infants without intrauterine growth restriction or who are…
