Pharmaceutical manufacturer Pfizer has announced that it will begin manufacturing its Covid-19 vaccine at its facility in Grange Castle in west Dublin.

It made the announcement today, saying since Pfizer and BioNTech started distributing their Covid-19 vaccine in December 2020, the companies have made several enhancements to the vaccine's supply chain.

These enhancements include expanding their existing facilities, adding more suppliers, and bringing on additional Pfizer/BioNTech sites and contract manufacturers around the world to produce the vaccine.

As such, Pfizer is now bringing on additional European-based facility to be a part of the global Pfizer-BioNTech COVID-19 Vaccine supply chain network and Grange Castle (Ireland) will contribute to the worldwide supply of the vaccine.

Up to $40m will be invested in Grange Castle and an additional 75 roles will be recruited, the company said.

"Pfizer’s Grange Castle facility will produce mRNA drug substance. Given the extensive technical transfer process, on-site development, equipment installation and regulatory approvals needed for the sites, we expect both facilities will be brought onto the network by the end of 2021".
