Use of Simple Mobile Technology to Create an Electronic Vaccination Registry in Kenya
Abstract:
Vaccination is one of the high-impact public health interventions
against the spread of disease. Over time, developed countries have been able to
reduce the burden of disease through improving access to vaccination and achieving
high vaccine coverage. In low-income countries, the situation is different as most
countries still report low coverages of less than 90%, which is the global target
recommended by the World Health Organization. The main reasons for this low coverage
include poor access to vaccination, stock-outs, and poor documentation and targeting
for vaccination services.
To address these problems, we developed an electronic vaccine registry using Unstructured
Supplementary Service Data (USSD) technology that registered births, vaccines administered
and sent short message reminders to mothers about their clinic dates. The study
was conducted in Nyandarua County, Kenya, between June 2018 to March 2019. To participate in the study, mothers had to reside within the jurisdiction of the study site. Mothers who moved
into the study site also had their children registered and previous vaccines updated. A total of 4,823 births and 20,515 vaccines administered were captured
into the system. The system
sent 12,554 short message reminders to mothers; 3 days before the due day and on
the due day. Additionally, it generated a birth register, vaccination register,
defaulter list, dropout rate report, vaccine coverage, and timeliness reports. The
intervention improved vaccination coverage and timeliness
of vaccination by up to 8.7%.
