Scientists of McMasters University, Canada have developed a new way to retain a vaccine without depending on extrinsic storage. Otherwise, vaccination preservation needs refrigeration. Vaccines are highly fragile as live virus in the vaccines are lost as soon as they don’t get the cold temperature for storage. Due to non-availability of refrigeration or cold storage at remote places, transportation of vaccines are not possible. The physicians take them out of refrigerator only before administering them. With the new technique it is possible now and can benefit a large population at far flung areas with the availability of vaccines.
Making of Room Temperature Vaccines
New vaccines so far are available for herpes and flu. This new technique uses the method of mixing commercial vaccines with sugar gel derivable from pullula. Pullulan is polysaccharide polymer and trehalose. This is a kind of sugar that uses combination two glucose molecules.
The Scientific Reports Journal publishes this technology in an article that is accessible. This new technique shall be available to other viral vaccines. This method makes it easier to preserve vaccines by simply mixing of vaccines and sugar molecules. Researchers find it as easy as stirring coffee and cream.
Storing of these vaccines are possible up to eight weeks, up to 40 degrees Celsius. The simple and cost effective process involves integration of low cost ingredients. It saves spending on refrigeration and feasible to make vaccines available at remote areas.
