The Salk polio vaccine, also known as the inactivated polio vaccine (IPV), protects against nervous system infection by preventing the virus from reaching the central nervous system. It does not protect against gastrointestinal infection, as it does not prevent the virus from entering the gut. It is not a subunit vaccine; it is an inactivated (killed) virus vaccine.
