Childhood Vaccination Timeliness Survey in Urban Gambia

Survey data from 355 children aged 24–35 months assesses coverage and timeliness of routine immunizations in urban Gambia. The dataset categorizes vaccine doses as 'early', 'timely', or 'delayed' based on national program windows. Bakalilu Kijera published this study on figshare in April 2026.

Use Cases

• Analyze timeliness rates for specific vaccines like Pentavalent 1 (75.4% timely) versus OPV booster (29.7% timely).
• Model factors associated with delayed doses, such as the Hepatitis B birth dose which had a 68.2% delay rate.
• Compare coverage trends between vaccines administered in the first year (0-11 months) and second year (12-23 months) of life.
• Use Kaplan-Meier survival analysis on the time-to-vaccination event data for different vaccine types.

Strengths

• Data from 355 surveyed children provides a sample for urban Gambia.
• Vaccination status is categorized into three specific timeliness groups (early, timely, delayed).
• Includes results for multiple vaccine types (e.g., Pentavalent, OPV, MCV, Hepatitis B).

Limitations

• Small sample size of 355 children limits generalizability.
• Geographic bias as data is only from urban areas of Western Region 1, The Gambia.
• Dataset size is 134.5 KB, indicating limited scope and likely a single summary table.
