Two years of COVID-19 vaccination in Nigeria: a review of the current situation of the pandemic: a literature review.

Curtailing COVID-19 outbreaks has been the major focus for many countries following the onset of the COVID-19 pandemic. Nigeria expanded its effort with the commencement of its vaccination program against COVID-19 in March 2021 after several less effective interventions as vaccine introduction was implemented. Following the introduction of the vaccines, Nigeria is expected to meet the worldwide COVID-19 eradication target of vaccinating 40% and 70% of the population, respectively, by the end of 2021 and 2022.
