Factors that affect vaccines availability in public health facilities in Nairobi City County: a cross-sectional study

Abstract

Introduction: over 1.5 million children die from vaccine-preventable diseases yearly. To avert these deaths and improve their livelihood, vaccine availability is important. The study assessed the availability of the vaccine, injection accessories and the associated factors in public health facilities in Nairobi City County and provided valuable data to contribute to improving healthcare infrastructure, stock management and vaccine distribution.

Methods: a descriptive cross-sectional study was conducted in 68 randomly selected public health facilities at Nairobi City County in Kenya. Data was collected using a researcher-administered structured questionnaire and more information abstracted from the Vaccines management tools. The analysis was carried out using STATA version 14.

Results: most facilities had experienced vaccines and accessories stock out at the time of the study and in the preceding twelve months. The most affected vaccines were tetanus (88%), measles-rubella (81%) and oral polio (79%). The causes of stockouts were rationing (82%), unavailability at the depot (93%), lack of transport (55%) and poor forecasting (50%). The majority (91%) of the facilities used the public transport system and only 1% had reliable government utility vehicles for delivery of vaccines and other logistics. Those near the vaccine depots preferred walking.

Conclusion: the public health facilities in Nairobi City County experienced frequent stockouts of vaccines and accessories thereby exposing the residents to vaccine-preventable diseases.
