Final answer:
The Salk vaccine, which uses inactivated poliovirus, is the example of an inactivated virus vaccine.
Step-by-step explanation:
The vaccine that represents the inactivated virus is the Salk vaccine. The Salk vaccine, introduced in 1955, uses an inactivated poliovirus and is delivered by intramuscular injection. Unlike the Sabin vaccine, which contains a live attenuated virus and is administered orally, the Salk vaccine poses no risk of transmitting the virus to others once it is administered. This is why in countries with a near-zero infection rate, such as the United States, the Salk vaccine is preferred over the Sabin vaccine. This choice is largely due to the risk associated with the Sabin vaccine, where the attenuated virus can potentially revert to a virulent form and lead to new cases of polio.
