Table 1 Variables used for analyses
Variables | Specifications | Remark | ||
|---|---|---|---|---|
Dependent | Children vaccinated | Total number of children vaccinated per vaccine | Used to calculate Vaccine Wastage Rate | |
Vaccine doses | Doses Received | Doses received by the health district during the month | ||
Doses in stock | Doses in the health district at the beginning of each month (Left-over doses from the previous month) | |||
Doses remaining (in sealed vials and not expired) | Doses left in the health district at the end of the month | |||
Doses used | Calculated from doses received, doses at the beginning and doses remaining | |||
Doses wasted | Calculated as difference between number of children vaccinated and doses used | |||
Independent | Seasons | Dry season | From December to May | Favorable conditions |
Rainy season | From June to November | Unfavorable conditions | ||
Setting | Rural Areas (12 HDa) | Poor road networks and electricity supply | Unfavorable | |
Urban Areas (12 HD) | Constant power supply and good road networks | Favorable | ||
Vaccines categories | Liquid | Oral polio vaccine | Wastage relatively easily managed through the Multi-Dose Vial Policy | |
PENTA (DTP-HepB Hib) vaccine | ||||
Pneumococcal conjugate vaccine | ||||
Inactivated polio vaccine | ||||
Rotavirus vaccine | ||||
Lyophilized | Bacillus Calmette-Guérin vaccine | Potential for conflict between reduction in vaccine wastage and Missed Opportunity to Vaccinate | ||
Measles and Rubella vaccine | ||||
Yellow fever vaccine | ||||
Oral vaccines | Oral polio vaccine | Easily administered | ||
Rotavirus vaccine | ||||
Injectable vaccines | PENTA (DTP-HepB Hib) vaccine | Not easily administered (liable to dose estimation and reconstitution errors) | ||
Pneumococcal conjugate vaccine | ||||
Inactivated polio vaccine | ||||
Bacillus Calmette-Guérin vaccine | ||||
Measles and rubella vaccine | ||||
Yellow fever vaccine | ||||
