New Incentives’ All Babies program operates in North West Nigeria (Jigawa, Katsina, and Zamfara states), a remote, poor region with one of the lowest childhood vaccination rates in the world. In partnership with local government partners, we provide small cash transfers to caregivers when their infants receive each of four vaccines: BCG (against tuberculosis), PENTA (against diphtheria, tetanus, whooping cough, hepatitis B and Haemophilus influenzae type b), PCV (against pneumococcal disease), and MCV (against measles). These vaccinations are part of the routine schedule for infant immunizations in Nigeria and are provided at no cost to the caregiver through government supported clinics. In addition, New Incentives addresses other barriers to immunization coverage, supporting partners to increase vaccine supply and increase awareness of the benefits of vaccines. We are constantly using data and evidence to inform our model and our daily operations.
