Given the fact that over 600 people got infected with measles in 2013 in the United States, and hundreds more die from the disease everywhere, scientists from the University of Colorado have developed a measles vaccine powder that has proven effective for human use and application.
According to the researchers, all a patient need do is just to inhale the measles vaccine powder and that did it; no need to bother about a syringe needle or mixing it with water before any storage anywhere. A patient only need to inhale it and that is all – making it even safe from contaminations that could result from other forms of administration.
Robert Sievers, professor in the Department of Chemistry and Biochemistry at the University of Colorado and a fellow of the Cooperative Institute for Research in Environmental Sciences states that “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.” He explains that most vaccine manufacturers make measles vaccines as dry powders, but healthcare providers add water in order to make them injectable.
Lamenting that measles is “a very, very infectious disease and we still have several hundred people dying every day from a measles-related disease”, Sievers added that “You’d think we’ve got to get past this somehow.” According to him, the new measles vaccines will come in vials for multiple doses but must be used up once opened, because storage overnight will damage it even if refrigerated.
About 60 males aged 18-45 were tested with the new inhalable measles power vaccine – but they were people that already had immunity to measles. They were divided into two groups, and one group inhaled it while the second group had it injected. 60% of the group that inhaled it didn’t show any negative symptoms, but it should be borne in mind that they already had immunity to the disease. But the researchers are working in Phase 2 and 3 trials to gather evidence about its safety and effectiveness as a inhalable measles vaccine powder.
