 The COVID-19 pandemic is an infectious disease caused by the SARS-CoV-2 virus that emerged in Wuhan, China in December 2019. Lockdown measures were introduced across Nigeria and other sub-Saharan Africa countries to mitigate the spread of the virus, but disruptions in vaccination services due to these measures have increased the risk of outbreak-prone vaccine-preventable diseases, highlighting the importance of maintaining essential services such as vaccination during emergencies. Achieving and sustaining high levels of vaccination coverage is crucial for all health systems during this period.
