According to the latest MICS survey carried out during the period from 2017 to 2018, two thirds of Congolese children, i.e., 2.5 million, have not received all the vaccines included in the vaccination schedule as defined by the Expanded Vaccination Program (PEV) in DR Congo.
These poor vaccine coverages had resulted in the emergence of some epidemics, namely polio and measles. The country is also facing the circulation of vaccine derived poliovirus responsible for epidemics of cDVPV polio and repeated epidemics of measles that affected all provinces.
