Which poliovirus vaccine is administered by injection?

Explanation:
Two polio vaccines exist: an oral, live-attenuated vaccine and an injected, inactivated vaccine. The vaccine given by injection is the inactivated poliovirus vaccine. It contains killed virus and is delivered by intramuscular injection, providing systemic immunity without any risk of causing polio. The oral vaccine uses a weakened virus and is taken by mouth, offering gut immunity and carrying a very small risk of vaccine-associated paralytic polio. There is no nasal spray polio vaccine in routine use.
