Inhalable Measles Vaccine

Will inhalable vaccine replace needle shots?

A new inhalable vaccine to prevent measles is ready to undergo its first trials on humans in India later this year. If successful, the trails could change the way future vaccines are administered.

To develop the vaccine, scientists mix liquid carbon dioxide with a weaken version of the measles virus. The process creates microscopic bubbles and droplets that dry out to be inhalable powder. Patients can then inhale the vaccine through a nozzle similar to the neck of a plastic water bottle.

To make the breakthrough, researchers at the University of Colorado at Boulder utilized a device known as the Carbon Dioxide Assisted Nebulization coupled with a Bubble Dryer, or CAN-BD. The device mixes two streams of fluid and then rapidly expands them to atmospheric pressure, before mixing in warm nitrogen to try the tiny bubbles and droplets.

Robert Sievers, a biochemist at CU Boulder explained:

One of our primary goals of this project is to get rid of needles and syringes, because they frighten some people, they hurt, they can transmit diseases and there are issues with needle disposal,

Sievers innovation also represents a cost-effective method, at just 26 cents per dose, or about the cost of an injectable vaccine.

The no-needles approach has proved popular elsewhere. Australian scientists have developed a postage stamp-sized vaccine patches that can deliver a tiny but effective dose through the skin.

But trypanophobes can also keep their fingers crossed for an inhalable treatment which delivers antibiotic particles for treating tuberculosis, or an inhalable treatment for the papilloma virus which causes cervical cancer.
