Dr. Javed N. Agrewala of the Institute of Microbial Technology (IMTECH), Chandigarh, recently described ongoing research to create a new TB vaccine by supplementing memory-enhancing cells called cytokines. These cells will enhance the human immune response making BCG vaccine last longer, thus leading to a drastic reduction in TB cases and TB transmission. He noted that although the prospect is promising, the vaccine is in its experimental stages. Dr. Agrewala explained that there is a need for this new vaccine because BCG mainly offers limited protection for children. By adulthood, the immune memory has died, and the adult is not protected from TB. Dr. D.N. Rao of the All India Institute of Medical Sciences added that by integrating nanoparticles and creating drugs and vaccines, the result will be super drugs. After being taken, the nanoparticles will slowly release the drug into the body so that dosage and frequency can be decreased. The doctors were guest lecturers at a national conference on CME in immunology, organized by the Central Indian Institute of Medical Science.
