Overview: AAV/lentiviral vector capacity — context, definitions, and current market posture.
What is AAV/lentiviral vector capacity?
AAV/lentiviral vector capacity refers to the global manufacturing infrastructure and throughput for adeno-associated virus (AAV) and lentiviral gene delivery systems. As of 2025, there are 28 cGMP-certified production sites across the US and EU dedicated to viral vector manufacturing, supported by $950 million in automation investments. These facilities collectively produce billions of vector genomes per batch, enabling large-scale clinical and commercial supply. Patent filings for viral vector manufacturing reached 430 in 2025, and non-viral delivery pipelines doubled, reflecting a 13% year-over-year capacity expansion driven by process innovation and automation.
Market snapshot
Current projections indicate the global gene therapy market is expected to reach an estimated $68 billion by 2033, reflecting a base-case Compound Annual Growth Rate (CAGR) of 21.2% from 2025. Within this, the CAR-T therapy market segment alone is forecast to achieve $21.5 billion by 2033. This growth is underpinned by a burgeoning clinical pipeline, with 1,420 active gene therapy clinical trials in 2025, projected to surpass 2,100 by 2033. Oncology represents the dominant therapeutic area, accounting for 64% of global gene therapy trials.
