VACCINE STORAGE WITH OUT REFRIGERATION


VACCINE STORAGE WITH OUT REFRIGERATION

Keeping medications cold from production until they are used in treatment is a costly process, accounting for as much as 80 percent of the price of vaccinations. The need for a cold chain has been a difficult for health care providers, aid organizations, scientists and pharmaceutical companies for decades, especially in settings where electricity is limited. Failures in the chain result in the loss of nearly half of all global vaccines

In an attempt to solve this problem, the scientists developed silk films that essentially wrap up the live bioactive molecules present in antibiotics and vaccines. This protects these essential bioactive elements, and so can greatly extend the shelf-life of the medication. The active drugs are released as the silk film is slowly degraded by enzymes in the body.The vaccines like measles, mumps, rubella and antibiotics like penicillin, tetracycline sect are tested using this method, and in all cases the silk film encapsulated medications remained potent far longer at elevated temperature. These advances could reduce the cost of vaccination programme.
