a new EPI vaccine. Among the range of users, the mother of the child in a

tory Trial constitutes the ethnographic site for an understanding of user c

e concluding section of the paper will compare and contrast providers' repr
esentations of the user with the users' self-representations as appropriato
rs of child health services in both the community and biomedical spaces.
