Biotechnological intervention has transformed the vaccination technology' – Discuss.
In short
Biotechnology has transformed vaccination by replacing slow whole-pathogen methods with DNA, protein sub-unit and mRNA platforms that are faster, safer and more precise. India's ZyCoV-D, CORBEVAX, GEMCOVAC-19 and the intranasal iNCOVACC show the shift, though regulatory delays and weak public-private links still limit it.

Ghissu Editorial · Verified 4 Oct 2026 · 256 words
Clinical Trial Infrastructure
India’s 54 clinical trial sites, including Andhra Pradesh, equipped with Good Clinical Practice (GCP) compliance and electronic data capture systems, enable rapid vaccine testing and real-time safety monitoring. This network supports accelerated vaccine development and robust data collection.
Bioinformatics and Genomic Surveillance
Integration of bioinformatics with biotechnology allows genome sequencing of pathogens and hosts, aiding vaccine design tailored to genetic diversity. The Department of Biotechnology’s One Day One Genome project enhances understanding of population genetics, critical for vaccine efficacy in diverse regions like Andhra Pradesh.
Improved Efficacy and Accessibility
Bharat Biotech’s Covaxin, which received WHO emergency use listing after rigorous trials, and thermostable intranasal vaccines like iNCOVACC improve immunogenicity and simplify storage and administration. These advances support India’s Universal Immunisation Programme, which annually reaches 2.9 crore pregnant women and 2.54 crore newborns.
