For the most part, no. Almost all manufacturers are subject to product liability. However, manufacturers in some industries enjoy special protections from liability in certain cases, perhaps none more so than the pharmaceutical industry. As an example, under federal law, a vaccine manufacturer can not be held liable for damages resulting from someone suffering unavoidable adverse side-effects of a vaccine, nor from failing to provide a warning about those side effects. (Of course, manufacturers could still face liability for, say, injuries caused by a tainted vaccine.)
Manufacturing industries of all stripes constantly lobby Congress and state legislatures to build protections for themselves against product liability into laws. It is important to hire an experienced Philadelphia product liability lawyer who stays on top of the constant developments in the law to represent you in any claim involving a defective product injury.
