Background: Lack of a timely receipt of vaccines can cause uncertain immune response and under-vaccination. Hence, timely vaccination is crucial to ensure an infant's early protection.
Objectives:To identify the age of presentation for the birth dose vaccines, vaccine antigens received and factors associated with vaccination presentation by day one in Northern Nigeria.
Method:A descriptive cross-sectional study involving 1 952 mother-infant pairs enrolled from 5 different states in Northern Nigeria. Data was collected using a questionnaire including the socio-demographic, antenatal care (ANC), delivery details, birth dates, vaccination presentation and birth vaccine antigens received. Data analysis was done with the SPSS-21 software.
Findings:The median age of the infants at presentation for birth vaccines was six (interquartile range 2-16) days. A total of 413 (21.2%) infants were brought by the day of birth (day 0) or the next day (Day one), while one-fifth (20.6%) presented after Day 28. The most frequently received antigen was the Bacille-Calmette-Guerin by 1 781 infants (91.2%), oral polio vaccine 1 703 (87.2%), and hepatitis B vaccine birth dose the lowest at 75.1% (1 565). The commonest reasons for delayed presentations were an ill baby (24.7%) and an ill mother (21.9%).
