Providing high-level expertise to meet compliance requirements to Manufacturer of next-generation vaccines


The COVID-19 crisis has launched a manufacturer of next generation vaccines into the spotlight, transforming it from a company that was pioneering research into mRNA technology into a large-scale drug manufacturer that is mostly managed through Contract Manufacturing Organizations (CMOs). The company was inundated by the enormous amount of data generated by CMOs and requested by regulatory authorities, and they needed expert and specific knowledge about handling data and a large number of people.

PMS offer

Particle Measuring Systems (PMS) has been offering consultancy support on a global scale since 2019, and its team is comprised of pharmaceutical manufacturing process experts with direct experience in the field. The services offered by PMS contribute to
their positioning as a leader in contamination monitoring, ranging from sterility assurance and quality and control assurance to
improving production processes. In short, the PMS Advisory Team provides high-level expertise to help its customers meet compliance requirements.

Creating a customer-win situation.

The collaborative relationship between the vaccine manufacturer and PMS was born thanks to the team’s reputation, high professional level, and proven experience. Key personnel contacted the team directly to request urgent Quality and Control support to assess that critical phase. What started as an arrangement to support vaccine manufacturer for a few months subsequently became a collaboration started in 2022 that the customer renewed again this year.

How does this apply to other customers?
The successful experience with a global vaccine manufacturer in the spotlight demonstrates how a high level of competence and knowledge increases PMS’ reputation by building a solid bond of trust over time. More and more clients have requested consultancy services thanks to recently hired key people who introduced PMS because they have collaborated with us successfully in previous work experience and trust us.

Solving challenges and advising on best practices

Challenge PSM Pharma, a PMS customer, requested help on how to best install a particle counter in a cleanroom where they planned to manufacture aseptically filled injectables, which need the highest purity of air quality in the pharma industry for manufacturing. One of our international Advisors from the USA helped with this relatively easy task on short notice. During this consultancy, it became clear that the end customer had several further projects on which our Advisory group could assist.
