Inundative, Dry-Powder, Inhaled Measles Vaccination to Prevent Deaths of Young Children in War-torn Regions.

Children living in war-torn and geographically remote regions often die from measles due to undervaccination. Protective community immunity could be safely improved through the comprehensive use of small, inexpensive, easy-to-use, dry-powder aerosolized measles vaccination inhalers. Influential local community members could be engaged to provide risk counseling and inform their peers of measles risks to inspire vaccine uptake. Vaccination by inhaled live attenuated measles vaccine has been shown to be safe and protective among several million research subjects and omits (1) needles, syringes, glass vials, and specialized disposal systems; (2) deadly vaccine reconstitution errors; (3) cold chain technology to protect temperature-sensitive vaccine; (4) vaccine wastage associated with suboptimal use of multidose vials; (5) trained vaccinators; (6) food, housing, and transportation costs associated with centralized vaccination campaigns; and (7) risk of violence to vaccinators and associated staff. All elements for inhaler-based measles vaccination are readily available. Dry-powder measles vaccine inhalers can be assembled and distributed to save lives.
