Measles is a highly contagious viral disease characterized by a rash. The first symptoms are usually a high fever, runny nose, a cough, red eyes, and small white sports on the buccal mucosa. Following this initial phrase, a rash of small red spots appears. The rash always begins on the face and neck before gradually spreading. After this phase, the rash fades, leaving a coppery discoloration followed by a fine desquamation. Convalescence lasts approximately a further 10 days.

In 2012 the World Health Organization (WHO) identified 122,000 measles deaths globally in spite of the availability of a safe and effective vaccine. This is partly due to lack of qualified personnel for performing injections. In this context, international organizations have collaborated to develop and license a measles aerosol vaccine.

AMP, for its part, has conducted a study on the acceptability of measles aerosol vaccine in disadvantaged regions
