LANDYS-CHOVEL, Mario. Alternative methods as part of the new trends in vaccine quality control. Vaccimonitor [online]. 2018, vol.27, n.3, pp. 110-118. ISSN 1025-0298.

Vaccine quality control is crucial for the manufacturing, lot release and commercialization activities worldwide. However, the current process is by-design too slow and expensive because is based on large animal assays for assuring the potency and safety of these important biological products. The development of 3Rs alternative methods (Reduction, Refinement and Replacement) is a trend able to significantly reduce the releasing times and costs of the vaccine quality control processes in the next few years. Particularly, the replacement of the animals-based potency and toxicity assays by alternative procedures more relevant, fast, accurate, reproducible and cheap, including serology, direct antigen quantification, cell culture tests and the Consistency Approach, for just mentioning some of them, implies a paradigm shift, with undisputable ethical, logistical, economic, scientific and technical repercussions for ensuring the vaccine quality parameters. Theoretical basements, advantages and implementation levels of the alternatives methods as well as their main limitations are presented in this paper

Keywords : Alternative methods; quality control; potency assay; toxicity assay; vaccines.
