Baboua–Abba is one of the health districts of the Nana-Mambéré region in the Central African Republic, close to the border with Cameroon. In January 2020, the EURECA team (MSF`s emergency team in CAR) set up an emergency intervention in this region to respond to an alert about the high number of children with measles, and to support the Ministry of Health in carrying out a vaccination campaign. It was the first time that MSF intervened in this part of the country, which has a very weak presence of international NGOs, and where many communities live in extremely remote and hard-to-reach areas where access to free healthcare remains a huge challenge. Most people rely on traditional medicine when they get sick. From March 6 to 24th, 2020 MSF mobile teams covered an enormous area, traveling to remote villages as well as to artisanal mining sites, to vaccinate almost 45,000 children between 6 months and 10 years old against measles. More than 7000 children between 6 weeks and 24 months also received PCV 13 (pneumococcal conjugate) vaccine.

During this vaccination campaign in the Baboua-Aba health district, MSF mobile teams have vaccinated 44, 994 children for measles (of an age between 6 months and 10 years) and of PCV13 (pneumococcal conjugate vaccine) (between 6 weeks and 24 months)
