This article investigates how technology interacts with underlying gender norms to
aspect health and human capital. The 1985 Turkish National Immunization Campaign
vaccinated under-five children against measles, polio, tetanus, diphtheria and pertussis.
The campaign was successful in reducing disability and increasing literacy and
educational attainment for the targeted beneficiaries. I find similar but smaller gains
of the campaign on human capital for older siblings who had an age eligible child in the
household. These spillover benefits accrue exclusively to older sisters and are larger if
the mother works outside the home. My findings suggest that older girl siblings most
often tasked with caring for young children when they are ill will also benefit from their
health improvement.
