A single dose aerosol chamber is used with a dispensing apparatus by users to take a chamber, fill the chamber with an aerosolized vaccine, and dispose of used chambers. A display provides instructions to encourage prompt inhalation by the user from a dispensed and filled chamber. The station allows very fast administration of vaccines to large numbers of people. The aerosol dispenser apparatus detects the chamber is in correct position and delivers a pre-determined dose of aerosol. The chamber has a nebulizer delivery port optimized for delivery of aerosol into the chamber container and to act as a vent during inhalation via the inhalation port.
