Impact of COVID-19 on routine immunization in Oyo State, Nigeria: trend analysis of immunization data in the pre- and post-index case period; 2019-2020

Abstract: Introduction the response to COVID-19 pandemic has posed new obstacles to the fragile health system, most especially in the area of vaccination across much of Africa. As the response to the pandemic intensifies through the application of non-pharmacologic interventions as well as enforcement of the lockdowns across African cities, there is a significant risk that more children will miss out on life-saving vaccines that can prevent childhood killer diseases.

“…Our study has demonstrated that childhood vaccination was the most affected during the pandemic. This aligns with numerous findings from various parts of the world [ 6 ], and is consistent with other studies which have shown significant declines in childhood vaccination coverage in Nigeria [ 42 , 43 ]. The pandemic-induced mobility restrictions and healthcare disruption were the primary cause of this decline, as evidenced by the fact that hard-to-reach rural and security-prone areas were most affected [ 42 44 ].…”

“…Hepatitis B, BCG, MCV and DTP-containing vaccine were most commonly discussed. For example, Babatunde et al found that the administration of post-natal antigen BCG fell by 3.7% and Hepatitis B by 3.5% in Oyo State of Nigeria [ 37 ]. For the third dose of Pentavalent, the cumulative reduction in doses administered between March and July 2020 ranged from 2% in Cameroon to 17% in Mali [ 28 ].…”

“…The COVID-19 pandemic substantially disrupted routine immunization services in the World Health Organization (WHO) African Region, leading to a precipitous decline in childhood vaccination rates compared to pre-pandemic levels [ 1 , 2 , 3 , 4 ]. The African Region is one of six WHO regions and comprises 47 of the 54 countries on the African continent [ 5 ].…”
