This image was created in August, 2014, by Centers for Disease Control and Prevention (CDC), Heath Scientist, and Special Assistant to the Director, Nancy S. Andrade, M.P.A., who captured the photograph while in Equatorial Guinea during a polio vaccination campaign. This was a group children, who’d received their vaccination, and were displaying their left pinky finger for the camera, verifying that they’d been vaccinated. It was also a sign to the community, that these children were taking care of their health, and taking part in a national initiative. This was one of the entries in the 2015 CDC Connects, Public Health in Action Photo Contest.
Part of the Children's Rights & Emergency Relief Organization's (UNICEF) role during the campaigns was to do monitoring in areas that the vaccinators had visited, in order to confirm that children had in fact been vaccinated. This photo was taken from the UNICEF vehicle that was performing this monitoring during the campaign. Nancy served as a Stop Transmission of Polio (STOP) Program Communications Consultant with UNICEF during this time.
