Study on Trend of Immunization Coverage in Mutum Biyu Ward "B" From 2016-2019 in Gassol Local Government Area, Taraba State, Nigeria

This study examines the trend of immunisation coverage for Bacille Calmette-Guerin (BCG), Oral Polio Vaccine (OPV), Measles, and Yellow Fever in Mutum Biyu Ward 'B' of Gassol local Government Area, Taraba State, Nigeria, from 2016 to 2019. The DHIS2 Nigeria platform was used to gather secondary data using a quantitative, cross-sectional approach. In order to analyse the completion and non-completion rates of Routine Immunisation (RI) schedules, vaccination cards and carer recollection were the main sources of immunisation histories. One-way ANOVA testing and descriptive statistics were used in the data analysis. The study's findings showed that vaccination coverage varied over time. The BCG coverage saw notable fluctuations, peaking in the years 2017 and 2019. In 2018, OPV coverage rose on average but somewhat decreased. Measles vaccination rates were steady at first, then they fell in 20l8 and then sharply recovered in 2019. The vaccination rate for yellow fever was low in 20l6, improved slightly in 2017, declined sharply in 2018, and then reached its peak in 2019. The study recommended localized use of geo-mapping to identify and map communities with low immunisation coverage in Mutum Biyu Ward "B" of Gassol LGA, Taraba State.
