Scale Up Or Scale Out? Choosing An Adherent Cell Culture Platform

As demand for animal and human vaccines accelerates, manufacturers face a pivotal decision that goes far beyond equipment selection. The choice between scaling out with roller bottles and scaling up with cell factory systems shapes everything from facility footprint and labor overhead to contamination risk and long-term sustainability. Facility space alone can run $500–$1,000 per square foot, and operational planning can stretch 12–18 months, meaning a poorly matched platform doesn't just slow production, it compounds costs at every stage of growth.

This article breaks down how each approach performs across the metrics that matter most in vaccine manufacturing, giving production and process development teams a practical framework for making the right call before committing to infrastructure. Read the full article to compare workflows and find the platform fit for your scale.
