MSD in Carlow

  • Employees in Carlow: 530
  • Activities: Filling

MSD have operated a site in Carlow since 2008.

The Carlow facility performs filling of vaccines, biologics and small molecule drug products. It was the company’s first “stand-alone vaccine and biologics facility” outside the US.

In 2022, the company announced significant investment in their Carlow site to build a new manufacturing facility. The facility will focus on “production of next generation oncology biologics” and its introduction is expected to lead to 100 new jobs. Recruitment for those roles is already underway and production is expected to begin in 2025.

In November 2022, MSD Carlow was awarded “Best Large Facility” at the Pharma Awards.

MSD in Cork

  • Employees in Cork: 600

MSD in Dublin

MSD invested over $1bn to repurpose and expand their former Dublin site to create “MSD Biotech, Dublin”, which was officially opened in November 2022.

MSD Biotech, Dublin is focused on manufacturing biologics-based medicines (including immuno-oncology). In fact, it is the company’s first “Large-Scale Mammalian-Based Drug Substance Facility”.

MSD in Meath

  • Employees in Meath: 300
  • Activities: Biologics manufacturing

MSD began operations in Dunboyne, Meath in September 2020. The site is the company’s first “Biologics Drug Substance single use commercialisation facility”. The combination of research and manufacturing teams within the site is expected to reduce the time it takes the company to get products to market.

Expansion capability was built in during development of the Meath site so the company already has the ability to increase production if business needs require it.

In 2021, MSD Dunboyne was highlighted by “Great Place to Work Ireland” as a “Best Medium Workplace” and a “Best Workplace for Women”.

MSD in Tipperary

  • Employees in Tipperary: 500
  • Activities: API manufacturing

MSD’s Ballydine, Tipperary site was established in 1976 and was the company’s first manufacturing site in Ireland.

The facilities here allow for development and manufacturing of active pharmaceutical ingredients and finished pharmaceutical products. The company describes the site as their “primary small molecule pipeline commercialisation facility globally” as well as “a European hub for quality, manufacturing, and engineering”. Products manufactured here are exported to 25 countries around the world (primarily throughout Europe, the USA and Japan).

In addition, the capability for formulation activities means that work on approximately 20 products in the MSD pipeline (i.e. currently in development) happens at the Ballydine site.

In 2022, MSD opened Ireland’s largest “self-generation solar project” at the site. The company is aiming to be carbon neutral by 2025 and this development means that approximately 20% of the Ballydine site’s power will come from renewable sources.

The Future of MSD in Ireland

MSD Ireland Human Health is one of Ireland’s leading healthcare companies and our vision is to be the number one, most valued and trusted healthcare company and employer in Ireland.
