Health Biotechnology — Overview
Health biotechnology (Red Biotechnology) applies biological systems to diagnose, prevent, and treat disease. For India, it sits at the intersection of strategic capability, public health equity, and global economic influence.
India supplies over 20% of global generic medicines by volume and accounts for more than 60% of global vaccine demand. This "pharmacy of the world" status rests on three pillars: a vast, cost-competitive manufacturing base; decades of public R&D investment; and a large, diverse patient population that makes India an ideal clinical-research hub.
Pharma exports reached USD 30.47 billion in FY 2024–25, registering 9.4% year-on-year growth (PHARMEXCIL data). The United States absorbs ~34% of exports, Europe ~19%, and the remainder is spread across over 200 markets.
India's Vaccine Industry
The Big Three Manufacturers
| Manufacturer | Headquarters | Key Vaccines / Products | Scale |
|---|---|---|---|
| Serum Institute of India (SII) | Pune | COVISHIELD (AstraZeneca), CERVAVAC (HPV), pentavalent, MMR, polio, influenza | World's largest by doses; >1.5 billion doses/year capacity; vaccines used in ~170 countries |
| Bharat Biotech | Hyderabad (Genome Valley) | Covaxin (BBV152), ROTAVAC, JENVAC (JE), Hillchol (cholera), rabies, chikungunya | >9 billion doses delivered globally; 19+ vaccines; WHO prequalification for multiple products |
| Biological E. Limited | Hyderabad | Corbevax (COVID-19), pentavalent DPT-HepB-Hib, Hib vaccine | Oldest private biologics firm (est. 1953); supplies >130 countries |
Key fact: About 65% of children in the world receive at least one vaccine manufactured by Serum Institute of India.
Why India Dominates Global Vaccine Supply
- Cost advantage: Manufacturing costs 60–80% lower than Western competitors due to labour, scale, and API access.
- WHO-prequalified facilities: Multiple plants qualify for UNICEF and Gavi procurement.
- Mission COVID Suraksha (2020–21): DBT mission that co-funded indigenous COVID vaccine development — accelerated both Covaxin and the Corbevax supply chain.
- BIRAC support: Biotechnology Industry Research Assistance Council (BIRAC) provides grants, equity funding, and technology transfer support to vaccine start-ups.
Types of Vaccines — Mechanism Comparison
| Type | Mechanism | Examples | Advantages |
|---|---|---|---|
| Live Attenuated | Weakened pathogen induces strong immune response | MMR, OPV (oral polio), BCG, chickenpox | Long-lasting immunity; often single dose |
| Inactivated / Killed | Killed pathogen; cannot replicate | Covaxin (BBV152), IPV, Hepatitis A | Stable; no risk of reversion |
| Subunit / Protein | Purified antigen (e.g., surface protein) | Corbevax (RBD protein), Hepatitis B, CERVAVAC (HPV VLP) | Highly safe; no live pathogen |
| mRNA | mRNA instructs cells to make antigen; no DNA entry into nucleus | Pfizer-BioNTech (BNT162b2), Moderna (mRNA-1273) | Rapid design; adaptable; no live pathogen |
| Viral Vector | Non-replicating virus delivers antigen gene | COVISHIELD (ChAdOx1), Sputnik V, J&J | Potent cellular immunity |
| Toxoid | Inactivated bacterial toxin | Tetanus, Diphtheria | Targets toxin, not bacterium |
mRNA Vaccine Technology
How mRNA Vaccines Work
- A synthetic messenger RNA (mRNA) strand — encoding the target antigen (e.g., spike protein) — is packaged in lipid nanoparticles (LNPs).
- LNPs fuse with cell membranes and deliver mRNA into the cytoplasm (not the nucleus; no DNA integration).
- Ribosomes translate mRNA → antigen protein is displayed on the cell surface.
- The immune system recognises it as foreign, generates antibodies and memory T/B cells.
- mRNA degrades within days; no permanent genetic trace.
Global mRNA Leaders
| Vaccine | Developer | Platform | Notable Feature |
|---|---|---|---|
| BNT162b2 (Comirnaty) | Pfizer–BioNTech | Conventional mRNA / LNP | First mRNA vaccine to receive full FDA approval |
| mRNA-1273 (Spikevax) | Moderna | Conventional mRNA / LNP | Higher dose; superior cold-chain stability |
| HGCO19 | Gennova (India) + HDT Bio (USA) | Self-amplifying mRNA (saRNA) | Lyophilised — less stringent cold-chain; smaller dose needed |
India's mRNA Vaccine Development
Gennova Biopharmaceuticals (Pune, subsidiary of Emcure), in partnership with HDT Bio Corp (USA), developed HGCO19 — India's first indigenous mRNA vaccine candidate for COVID-19, funded by DBT under Mission COVID Suraksha.
Key differentiator: Gennova's platform uses self-amplifying mRNA (saRNA) — the RNA encodes its own replication machinery, so a much smaller dose achieves the same immune response. This is particularly suited to low- and middle-income countries where cold-chain logistics are a challenge.
In 2025, Gennova received expanded CEPI funding (up to USD 13.38 million) to develop a saRNA vaccine against Nipah virus — demonstrating that India's mRNA platform has moved beyond COVID-19.
Exam tip: mRNA vaccines do NOT alter DNA. The mRNA never enters the nucleus. This is a frequent Prelims distractor.

GenomeIndia Project
Overview
| Parameter | Detail |
|---|---|
| Launched | 2020 — announced by PM Modi; funded by Department of Biotechnology (DBT) |
| Lead institution | Centre for Brain Research, Indian Institute of Science (IISc), Bengaluru |
| Consortium | 20 academic and research institutions across India |
| Milestone | Sequencing of 10,074 whole genomes completed — announced 27 February 2024 |
| Population coverage | 99 diverse communities; 85 distinct population groups (32 tribal + 53 non-tribal); all major linguistic and social groups |
| Variants identified | ~180 million genetic variants (including 130 million on autosomes, 50 million on sex chromosomes); over 135 million variations identified as common and rare variants unique to Indian subgroups |
| Data size | ~8 petabytes |
| Data repository | Indian Biological Data Centre (IBDC), Faridabad — India's first national life-science data repository |
Key Findings and Applications
- Large proportion of identified variants are unique to South Asian or Indian sub-populations — not found in global reference databases (HapMap, 1000 Genomes Project).
- Enables development of India-specific polygenic risk scores for diseases such as type 2 diabetes, cardiovascular disease, and psychiatric disorders.
- Foundation for precision medicine tailored to India's genetic diversity.
- Data is accessible to Indian and global researchers via IBDC portals (Framework for Exchange of Data — FeED protocol launched alongside the data release).
Prelims fact: GenomeIndia's data is stored at IBDC in Faridabad, established by DBT at the Regional Centre for Biotechnology (RCB).
Pharmacogenomics — Precision Medicine for India
Pharmacogenomics studies how genetic variation affects an individual's response to drugs — determining whether a drug will be effective, ineffective, or toxic for a given patient.
Why India Needs Its Own Pharmacogenomic Data
| Issue | Implication |
|---|---|
| Most drug dosage guidelines are based on European/Western genetic data | Standard doses may under- or over-medicate Indian patients |
| India has extreme internal genetic diversity (tribal, caste, linguistic groups) | A single "Indian average" is misleading |
| Known variant: CYP2C19 enzyme (metabolises clopidogrel, proton pump inhibitors) | Frequencies differ significantly between Indian communities and Western populations |
| TPMT variants affecting mercaptopurine metabolism | Relevant for childhood leukemia treatment in India |
GenomeIndia data will enable the construction of India-specific pharmacogenomic reference panels — a critical input for the shift to precision medicine.

ICMR Guidelines for Clinical Trials
ICMR's National Ethical Guidelines for Biomedical and Health Research Involving Human Participants (2017, revised) govern:
- Informed consent procedures.
- Compensation for trial-related injury.
- Special protections for vulnerable populations.
- Post-trial access to beneficial interventions.
Important: India amended the New Drugs and Clinical Trials Rules in 2019 — streamlined timelines, allowed academic clinical trials with reduced fees, and introduced provisions for orphan drugs and rare diseases.
Challenges in India's Health Biotech Sector
| Challenge | Detail |
|---|---|
| API dependence on China | ~72% of API imports from China — supply-chain risk exposed during COVID; policy response through PLI and Bulk Drug Parks |
| Regulatory capacity | CDSCO under-staffed relative to the volume of applications; delays affect innovation |
| IP vs. access tension | TRIPS flexibilities (compulsory licensing under Section 84, Patents Act) vs. attracting global pharma R&D investment |
| Cold-chain infrastructure | mRNA and some subunit vaccines require ultra-cold storage (−20°C to −70°C); rural cold-chain gaps remain |
| Clinical trial perception | Past controversies (2013 suspension of new trial approvals) damaged India's reputation; reforms since 2015 rebuilding confidence |
| Data governance for genomics | GenomeIndia data is 8 petabytes of sensitive genetic information; robust privacy and access frameworks (FeED protocol) are under development |
| Talent pipeline | Shortage of clinical pharmacologists, bioinformaticians, and regulatory scientists |
