An analysis assessing changes in the cost of delivering immunization through outreach in Tanzania and Indonesia estimated that adding handwashing stations and hand sanitizer at outreach sites could increase the delivery cost per dose by 11-14%, by 45-61% when adding PPE (mask, gloves, goggles), an additional 9% if adding a crowd controller, and up to 42% for additional staff with infrared thermometers. If facility-based coverage drops by 50%, the cost of increasing outreach to compensate could add up to another 11% per dose.
