Measles is a highly communicable disease and can be transmitted with ease across the length and breadth of any nation. According to W.H.O, “Measles is one of the most readily transmitted communicable diseases and probably the best known and most deadly of all childhood rash/fever illnesses.”
The quest for an effective vaccine against measles has been going on for some time now. New research has indicated that it would be possible to administer the vaccine a dry, inhaled powder.
Robert Sievers, from the Department of Chemistry and Biochemistry at the University of Colorado-Boulder, says “Delivering vaccines in the conventional way, with needle injections, poses some serious challenges, especially in resource-poor parts of the world. You don’t need to worry about needles; you don’t need to worry about reconstituting vaccines with clean water; you don’t need to worry about disposal of sharps waste or other vaccine wastage issues; and dry delivery is cheaper.”
Sievers explain that vaccine manufacturers already make measles vaccines as a powder. However hospitals and clinics but hospitals and health clinics add water in order to make the vaccine inject able.
Sievers and his team have developed the inhalable dry powder measles vaccine (MVDP). Another heads up by using this process is that it negates the need for liquid storage and reduces or eliminates the chances of cross contamination which can happen during the reconstitution of the older vaccine with water.
As per the researchers, “MVD was well tolerated in all subjects. Most subjects had high baseline measles antibody titer which limited ability to measure the serologic responses, and may have limited the adverse events following vaccinations.”
It is a welcome development but the scientists have cautioned that more testing are necessary before the vaccine can be approved for human use. The vaccine is in the form of a dry powder and is administered with a puff of dry air.
