Adherence to COVID-19 vaccination in riverside populations of the municipality of Careiro/AM.

The sample was convenience-based and small, with 152 adults from two riverside communities, so it may not represent other remote populations. Vaccine doses, comorbidities, and prior COVID-19 diagnosis were self-reported, without documentary evidence. The study was cross-sectional, so it describes what people said at one point and cannot show why they did or did not vaccinate. Only people aged 18 years or older who could understand the interview were included, so children and people with severe illness, impaired consciousness, communication difficulties, or vaccine contraindications were not studied. Geographic isolation, transport, and seasonal Amazon conditions affected data collection, so some residents may not have been reached.

The paper reports support from FAPEAM through a graduate support program. It does not report commercial conflicts of interest.

Do not read the 56.29% no-intention figure as proof that people cannot access vaccines. In this survey, 99% had received at least one dose and 80.13% said access was very easy, while 80.92% had heard negative information.
