Vaccination Coverage and Factors Associated With Incomplete Vaccination Schedules in Children Under 5 in a Peripheral Area of the Federal District of Brazil.
Ivea Rayane Mendes Nicacio Viana, Henry Maia Peixoto
PMID 41612572WHAT IT FOUND
19.75% of children had incomplete schedules, and 82.09% had at least one late dose.
Incomplete schedules were more common in children under 2, when vaccines were not all given at the same site, and when caregivers reported pandemic barriers.
Key findings
01In the 162 children assessed, 19.75% had an incomplete vaccination schedule and 82.09% had at least one dose outside the recommended age.
02Valid-dose coverage exceeded 90% for all vaccines, but no vaccine reached the target for correct-dose coverage.
03Incomplete schedules were more common in children aged 6 months to under 2 years, when vaccines were not all given at the same location, and when caregivers reported pandemic vaccination difficulty.

What it does not show
The study did not reach its planned sample size, so the estimates may be less precise. It was cross-sectional, so it cannot show that age, moving between sites, or pandemic difficulty caused incomplete schedules. The survey covered two health units in a peripheral area, so results may not apply to other regions or better-resourced areas. Caregiver reports and photographed booklets were used; some reasons for delay were self-reported and may be incomplete. Primary-care perception scores were subjective and did not explain the incomplete schedules.
Declared interests
The study received grants from CNPq/Brazil, and CAPES funded the article processing charge. The authors declared no conflicts of interest.
The easy way to misread this
Do not read the high valid-dose coverage as evidence that vaccination was timely. Many doses were late, and correct-dose coverage missed the target.
