EarLy extra Measles immunisation during a measles Outbreak
Measles infection in children
Participation in this study entails five heel- or fingerstick blood collections of 250-500 µl for the MMR-0 group and three heel- or fingerstick blood collections of 250-500 µl for the control group. Optionally, five or three venepunctures of 4 ml per sampling time point are performed, respectively, if parents decide to participate in the cellular immunity part of this study. To gain a better insight in the maternal antibodies in the child, the biological mothers of MMR-0 immunised children will be asked for an optional blood sample by fingerstick of 300-800 µl.
