Established during the ‘Swadeshi Movement’ of India, Biological E. Limited (BE) started during a time when the nation sought access to critical healthcare products. Founded and led by Dr. DVK Raju, Biological E. Limited commenced its operations in 1953 as a biological products company manufacturing liver extracts and anti-coagulants.

With an objective of transitioning from treating diseases to preventing them, Biological E. Limited launched its Biotechnology Division (now Vaccines and Biologics Division) and commenced large-scale production of DPT vaccines as early as 1962.

Biological E. Limited continues to evolve as an organisation and currently has four strategic business units: Branded Formulations, Speciality Generic Injectables, Synthetic Biology and Vaccines and Biologics.
