All children will get the recommended MV by 9 months of age.\n\nThe study will enroll 2400 non-pregnant HIV-negative women, who will be randomized 1:1:1 to one of three injections: BCG, MV, or placebo (saline). The first 100 children born to mothers from each of the three groups and surviving until 20 weeks of age will be selected for follow-up. Within strata of maternal vaccination (BCG, MV, placebo) they will be randomized 1:1 to early MV at 20 weeks, or placebo (saline). Thus, a total of 6 groups (A-F) will be formed.\n\nBy 9 months of age, 20 children in each randomization group will receive a yellow fever (YF) vaccine and then MV 5 days later. All other children will receive an MV and a YF vaccine when they reach 9 months of age.\n\nSetting:\n\nBHP's Health and Demographic Surveillance System (HDSS) covers six districts in the capital of Guinea-Bissau with around 100,000 individuals. The BHP follows all women of fertile age with monthly visits to register new pregnancies. All children are followed with 4-monthly home visits for infections, hospitalizations, and vaccinations. All vaccinations administered at the three health centers in the study area are documented by BHP. Furthermore, BHP monitors all consultations and admissions at the health centers and all pediatric consultations and admissions at the national hospital.\n\nEnrolment and randomization of women:\n\nEligible women will be identified through the BHP HDSS. They will receive a home visit by a project assistant, who will explain the study. If they are interested in participating, they will be asked to come to a nearby health center. Here, following informed oral and written consent, a blood sample will be drawn and tested for HIV. If the HIV-test is positive, immediate counseling will be given by a trained project nurse and the woman will be referred to the HIV clinic, per current standard of care. A urine pregnancy test will be carried out. Provided negative HIV and pregnancy tests, an interview regarding background factors, including previous vaccinations, will be carried out. Finally, the woman will be randomized and treated according to the allocation.\n\nFollow-up for pregnancies and morbidity:\n\nWomen will be followed for pregnancy. All participating women will also be followed with respect to morbidity (consultations, hospitalizations) at 2-monthly interviews and continuous documentation of hospitalizations and consultations.\n\nMaternal blood samples:\n\nAll blood will be collected into Na-Heparin tubes. Baseline blood sample: All women enrolled will have a blood sample obtained by venipuncture at baseline, in conjunction with the HIV screening, just before randomization.\n\nBaseline+4weeks blood sample: A blood sample will be obtained after 4 weeks from 30 women from each group. These samples with be paired with the baseline sample to assess measles-specific antibodies level.\n\nChildren:\n\nAll children will be followed closely through monthly home visits, during which the mother will be encouraged to bring her child for the scheduled vaccines. At 20 weeks of age, the children will be invited for further randomization.\n\nInclusion criteria: The first 100 children surviving until 20 weeks of age from each group of enrolled mothers, and having received all recommended vaccines, the 3rd pentavalent vaccine at least 6 weeks before, are eligible for further study randomization.\n\nExclusion criteria: Exclusion criteria are lack of receipt of all scheduled vaccines, pentavalent vaccine less than 6 weeks ago (in which case children are asked to come back once 6 weeks are reached), and overt illness (in which case they will be referred for treatment and invited to come back when the child is well again).\n\nRandomization of children:\n\nEligible children are identified at the monthly home visits and asked to come to a nearby health center in the afternoon. Here, provided maternal consent, they will be randomly allocated to early MV or placebo (saline).\n\nChild blood samples:\n\nAll blood will be collected into Na-Heparin tubes. Measles specific arm: N=30 from each of Groups A-F: A 2 ml blood sample will be obtained at baseline (either 20 weeks of age or 9 months of age) and a second sample of 2 ml will be obtained at either 9 months of age (those bled first at 20 weeks of age) or 18 weeks after 9-month-vaccination (those bled first at 9 months of age) for assessment of measles-specific antibodies levels.\n\nNon-specific effect arm: N=20 from each of Groups A-F: Children will receive YF vaccine at 9 months of age, a blood sample will be obtained just before and a second sample will be obtained 5 days later for assessment of YF viraemia.\n\nFollow up for child morbidity and mortality:\n\nThe 300 children enrolled in the child-vaccination part of the study as well as other children born to the 2400 women enrolled in the maternal vaccination study will be followed for morbidity and mortality. The data collection with be based on the HDSS regular home visits, the registration of consultations in the study area, and the registration of admissions to the pediatric ward of the national hospital.\n\nVaccination and blinding:\n\nWomen vaccination: Women will be vaccinated in right upper arm. The vaccine administrator will know what is given, but the women will not be told before the trial has come to an end.\n\nChild vaccination: MV and YF vaccine will be given subcutaneously according to the national recommendations. Placebo for MV at 20 weeks will be saline, provided subcutaneously in the same volume as MV.\n\nAnalysis of blood samples:\n\nThe blood samples will be analyzed in collaboration with our international colleagues.\n\nMeasles antibodies: Total and measles-specific immunoglobulin G (IgG) levels will be analyzed.\n\nYF vaccine response: Children will receive a single dose of YF vaccine. A blood sample will be obtained 5 days after and tested for yellow fever viral load.\n\nStatistical analysis and sample size:\n\nMaternal and child morbidity data will be analyzed in standard survival analysis for time-to-event data to compare potential differential effects by vaccination allocation. The analysis will take into account other possible interventions or events, campaigns or epidemics, occurring during the period of follow-up.\n\nThe study sample size of 2400 women is based on the anticipated delivery rates in the area. Based on census data from BHP, the annual incidence of new deliveries in women with one child of 12 months will be around 15%. Hence, with a cohort of 2,400 enrolled women, it is expected to register \\>300 deliveries in the 5th -10th trimester after enrolment starts.",[49,55,60],{"label":50,"type":51,"description":52,"interventionNames":53},"Measles vaccine","EXPERIMENTAL","Measles vaccine in standard dose of 0.5 ml.",[54],"Biological: Measles vaccine",{"label":56,"type":51,"description":57,"interventionNames":58},"BCG vaccine","BCG vaccine in standard dose of 0.1 ml.",[59],"Biological: BCG vaccine",{"label":61,"type":62,"description":63,"interventionNames":64},"Placebo","PLACEBO_COMPARATOR","Saline injection",[65],"Other: Placebo",[67,71,74],{"type":68,"name":56,"description":69,"armGroupLabels":70,"otherNames":34},"BIOLOGICAL","It is an attenuated live bacterial vaccine.
