Minimizing disruptions to immunization services in the context of COVID-19 in Senegal:lessons learnt and policy options

The COVID-19 pandemic revealed the vulnerability of essential health services globally and caused major disruptions, particularly in immunization services. In 2020, an estimated two thirds of 105 countries reported disruptions to routine facility-based and/or outreach immunization services (WHO, 2020b). Within the same year, an estimated 23 million children missed out on basic childhood vaccinations, accounting for the highest number since 2009 and representing a significant increase from 2019 (UNICEF, 2021; WHO, 2021a). Some settings experienced an upsurge in deadly diseases, such as measles outbreaks observed in Nigeria and Côte d’Ivoire between late 2020 and early 2021 (WHO, 2022a). The indirect effects of the pandemic on routine immunization services will likely lead to increased illness and death for many years, particularly among vulnerable populations such as women and children.
