The USPTO has granted patent to a new vaccine adjuvant extracted from Ashwagandha which is an Indian plant used as an immunity enhancer. The grant is a welcome move since it could lead to research and development of more vaccines which could help in improving the immune system. The new vaccine is found to possess many advantages as compared to the traditional vaccines. It has shown great effect for many diseases such as tetanus, diphtheria and meningitis. A patent was granted for the same in India. The patent was granted to Serum Institute of India and the University of Pune. Ashwagandha was tested on mice as well as on rats which gave positive feedback. The advantage of Ashwagandha is that it helps patients to better react to the vaccine and also help in reducing the intake of dosage.
