A vaccine vial usually has a small rubber stopper under a metal seal, and a prefilled syringe has a plunger that touches the drug inside. West Pharmaceutical Services makes parts like these, along with cartridge components and devices that deliver injectable drugs. An injection you have had may well have used West parts. Its customers are drug makers, from producers of biologics (medicines made from living cells) to generic drug companies. They pay for parts that keep a drug stable and clean. Regulators in the U.S., Europe and China oversee some of these parts and the drugs that use them.
