About this trial

Receiving all four doses of the malaria vaccine can significantly protect children against malaria illness, hospitalization, and death. However, in Ghana, only 46% of children complete the full vaccination sequence. More broadly, many children in Ghana do not receive the full set of recommended pediatric vaccinations. To address this, Simprints, in collaboration with Ghana Health Services, will implement a digital vaccination record system linked to biometrics. This system will automatically identify children who are behind on their vaccination schedule, providing health workers with information to prioritize community outreach. Additionally, it will send voice message reminders to caregivers to improve compliance. A cluster-randomized controlled trial (c-RCT) will be conducted in the Oti region to measure the impact of this innovation on the proportion of children completing malaria and routine vaccination schedules.

Treatments tested in this trial

  • HEALTH FACILITY INTERVENTION

    Behavioral

    Health facilities randomized in treatment clusters will be provided with a digital vaccination record system (e-tracker) linked to biometrics (facial recognition) of caregivers (if child is below 6 months) or of children (if child is above 6 months). With the support of Ghana Health Services, Simprints will train CHWs on digital vaccination record system (e-tracker) and biometrics. Simprints will also provide Technical Assistance to CHWs for the duration of the study.

  • INDIVIDUAL INTERVENTION

    Behavioral

    Caregivers (if child is below 6 months) or children (if child is above 6 months) living in communities in the catchment areas of health facilities randomized in treatment clusters will be registered at the community level into the e-tracker and biometrics (facial recognition), and caregivers of children who are due for or missed vaccination will receive voice message appointment reminders if they provided a phone number during the registration in biometrics. Reminders will be sent before a child is due a visit to receive vaccination, as well as after a child missed his due visit.

Trial outcomes

Primary outcomes

1

Completion of full malaria sequence (Index children)

Record of 4 doses of malaria vaccines for the index child recorded by the individual child's booklet (or self-reported by the mother if the booklet is not available)

Time frame
Measured at endline, 24-26 months after baseline
2

Timely full malaria vaccination (Index children)

Record of 4 doses of malaria vaccines for the index child recorded by the individual child's booklet (or self-reported by the mother if the booklet is not available) taken within the appropriate time frame.

Time frame
Measured at endline, 24-26 months after baseline
3

Completion of full routine vaccination sequence (basic antigens) (Index children)

Records of doses of routine vaccines (basic antigens) for the index child recorded in the individual child's booklet (or self-reported by the mother if the booklet is not available). Defined as receipt of all of the following: One dose of BCG vaccine; Three doses of polio vaccine given as oral polio vaccine (OPV); Inactivated polio vaccine (IPV); Three doses of Pentavalent vaccine (Penta); One dose of measles-rubella vaccine (MR).

Time frame
Measured at endline, 24-26 months after baseline
4

Completion of full routine vaccination sequence (national schedule) (Index children)

Records of doses of routine vaccines (national schedule) for the index child recorded in the individual child's booklet (or self-reported by the mother if the booklet is not available). Full vaccination coverage based on the national schedule is defined as the index child having received all the following: BCG; Three doses of Pentavalent (Penta); Four doses of OPV (including OPV given at birth); One dose of IPV; One dose of yellow fever vaccine; Three doses of pneumococcal vaccine (PCV); Three doses of rotavirus vaccine; Two doses of measles-rubella vaccine (MR); One dose of meningitis A vaccine (MenA).

Time frame
Measured at endline, 24-26 months after baseline

Time frame
Measured at endline, 24-26 months after baseline
2

Timely full routine vaccination sequence (national schedule) (Index children)

Time frame
Measured at endline, 24-26 months after baseline
3

Early, Late or Very Late malaria vaccination (Index children)

Record of 4 doses of malaria vaccines for the index child recorded by the individual child's booklet (or self-reported by the mother if the booklet is not available). Taken outside the appropriate time frame.

Time frame

4

Early, Late or Very Late full routine vaccination sequence (basic antigens) (Index children)

Records of doses of routine vaccines (basic antigens) for the index child recorded in the individual child's booklet (or self-reported by the mother if the booklet is not available). Taken outside the appropriate time frame
