From: Attention to COVID 19 pandemic resulted in increased measles cases and deaths in Zambia
Trends in measles vaccine coverage (MCV1 and MCV2) pre and post the COVID-19 pandemic in Zambia (2017–2023). Data points represent monthly vaccination rates for MCV1 (Measles Containing Vaccine Dose 1) and MCV2 (Dose 2) from 2017 to 2023. The gray-shaded area highlights the COVID-19 pandemic period in Zambia. Dashed lines show fitted estimates using a linear step-change model, while the curved lines represent seasonally adjusted fitted values. The figure illustrates the decline in MCV2 coverage during the pandemic, with no significant disruption observed for MCV1
