Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Prophylaxis, Efficacy

The follow-up study has one primary aim:
To measure the level of specific immunity, measured as level of measles neutralising antibodies by plaque-reduction neutralisation test 1-3 years after routine MMR vaccination at 4 years of age and compare this level between the two original MMR groups: The one, which received an early MMR and the one, which received placebo in the trial .

Secondary objectives 1

  1. • Level of specific immunity, measured as level of measles neutralising antibodies by plaque-reduction neutralisation test at least 1 year after MMR2. • Level of specific immunity, measured as level of IgG against measles at least 1 year after MMR2. • Level of specific immunity, measured as level of IgG against measles at baseline (in the original trial, if we have that information) will be taken into consideration when reporting this secondary outcome. • IgG against mumps and rubella at least 1 year after MMR2. Level of specific immunity, measured as level of IgG against mumps and rubella at baseline will be taken into consideration when reporting these secondary outcomes. • The associations between level of maternal specific immunity against measles, mumps and rubella and the child’s specific immunity against measles, mumps and rubella will be studied. • Influence of mother’s birth year (before 1986, between 1986-87 or after 1987) as a proxy for maternal immunization status will be studied as well. • The decay rate between two sampling time points will be calculated for those individuals, who we collect consecutive samples from.
