Vaccination
What predicts full childhood immunization in Senegal
Open access · cc by · source: Europe PMC
Only 62.8% of Senegalese children 12–23 months were fully immunized; maternal education, wealth, and antenatal care strongly predicted coverage.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Multiple studies in this library examine vaccination with empirical patient or population outcomes rather than opinion alone.
Evidence for the claim as stated.
Complete coverage was 62.8%, below national (>80%) and international (>90%) goals; four antenatal visits associated with AOR 3.10 for complete immunization.
Evidence for the claim as stated.
In three West African DHS samples, full infant vaccination was about 15% and tracked care access more than child sex.
Pooled 2019–20 DHS data for 5,368 children aged 0–12 months in The Gambia, Sierra Leone, and Liberia found full vaccination ~15.1% (males) and ~15.0% (females). Postnatal-care visits associated with higher odds (aOR 1.23); lower odds with father’s primary education (aOR 0.67), never watching TV (aOR 0.68), and only 1–3 antenatal visits (aOR 0.59).
Scope note — Senegal 12–23-month complete-immunization estimate uses a later age window than 0–12-month ‘full’ status
Limits the claim's scope: a different population, assay, or outcome.
Effect sizes and settings differ across vaccination studies — digital vs clinic, trial vs observational — so results should not be pooled casually.
Evidence for the claim as stated.
Senegal’s 62.8% complete immunization among 12–23-month-olds is not the same claim as ~15% ‘full’ coverage among 0–12-month infants in The Gambia, Sierra Leone, and Liberia. Age windows, schedules, and ‘complete/full’ definitions differ, so the percentages should not be pooled as one West African coverage rate.
Evidence for the claim as stated.
In Senegal's 2010–2011 DHS, complete immunization among 2,199 children aged 12–23 months was 62.8%, below national (>80%) and international (>90%) goals. Four antenatal visits were associated with AOR 3.10 for complete immunization (card or maternal recall). That is an adjusted association in survey data, not a trial of an outreach programme, and recall can misclassify doses.
Evidence for the claim as stated.
The same odds-ratio language is asked to do two different jobs. Senegal's AOR 3.10 and the CDI 36% excess odds are observational associations after covariate adjustment. Text4Heart's AOR 2.55 is a randomised contrast that itself was gone by 6 months. Reading every AOR as if it were that trial overclaims the survey papers and understates how fragile a trial AOR can be once follow-up continues.
Evidence for the claim as stated.
Diagnostic papers optimise a cutoff, not an exposure odds ratio. CA125's PPV of 10.1% at a guideline threshold is a rare-disease problem; the diabetes score's NNS of 3–7 is a screening-workload problem that tracks prevalence, not AUC. Those operating-point numbers are not interchangeable with an immunization AOR of 3.10.

What predicts full childhood immunization in Senegal
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Complete immunization coverage was 62.8%.
The prevalence of complete immunization coverage among all children was 62.8% (Table ).
What maternal education pattern was noted?
More than half of women (68.7%) had no formal education and nearly 50% (43.8%) were classified as “poor/poorest” (Table ).
Key findings
Complete coverage was 62.8%, below national (>80%) and international (>90%) goals; four antenatal visits associated with AOR 3.10 for complete immunization.
Methodology
Secondary analysis of Senegal 2010–2011 DHS data for 2,199 children aged 12–23 months examined complete immunization (card or maternal recall) and maternal/household predictors.
Limitations
Causal effects of specific outreach programs, and recall-based vaccination histories can misclassify doses.
