ABSTRACT
OBJECTIVES: This study compared the infant vaccination trends a year before and a year after the onset of the COVID-19 pandemic in selected urban and rural communities in Ibadan, Nigeria.
DESIGN: This was a cross-sectional study in which data were extracted from infant vaccination records.
SETTING: Two rural and three urban vaccination centres in primary health clinics at Ibadan Southeast and Olúyòlé local government areas, respectively.
PARTICIPANTS: Infant vaccination records 1 year before and 1 year after the onset of the COVID-19 pandemic (March 2019-February 2020 and March 2020-February 2021, respectively).
OUTCOME MEASURES: Timeliness of vaccination (vaccination taken within 2 weeks of appointment) and vaccination completion according to the Nigerian routine infant vaccination schedule.
RESULTS: 2000 vaccination records were included in the study (1013 (50.6%) for male infants). 840 (42.0%) of the records were from the rural immunisation clinics. There were 1194 (59.7%) and 806 (40.3%) records from before and after the onset of the COVID-19 pandemic, respectively. Before the pandemic, birth dose vaccines were timelier among infants from urban communities, while vaccines given at 6 weeks were timelier in the rural areas. Following the onset of the pandemic, the rural communities had a higher proportion of infants with timelier and complete vaccination except for the birth dose vaccines. Overall, there was higher vaccination completion before the pandemic, and this was higher in the rural compared with the urban communities both before (54.8% vs 11.7%) and after (23.6% vs 1.0%) the onset of the pandemic.
CONCLUSIONS: A decline in infant vaccination uptake, timeliness and completion persisted 1 year after the COVID-19 pandemic onset, and urban communities were more affected. More efforts are required to ensure optimal infant vaccination, especially in urban communities, to forestall outbreaks of vaccine-preventable diseases.
