Suspended cell lines for inactivated virus vaccine production.

INTRODUCTION

Inactivated virus vaccines are the most widely used tool to prevent disease. To meet vaccine production demands, increasing attention has been placed on identifying methods to improve vaccine production efficiency. The use of suspended cells can greatly increase vaccine production. Suspension acclimation is a traditional method to convert adherent cells to suspension strains. Furthermore, as genetic engineering technology has developed, increasing attention has focused on the development of suspension cell lines using targeted genetic engineering techniques.

AREAS COVERED

This review systematically summarizes and analyzes the development and research progress of various inactivated viral vaccine production suspension cell lines and provides protocols and candidate target genes for the engineered establishment of additional suspension cell lines for vaccine production.

EXPERT OPINION

The use of suspended cells can significantly improve the production efficiency of inactivated virus vaccines and other biological products. Presently, cell suspension culture is the key component to improve many vaccine production processes.
