What does the Inactivated Poliovirus Vaccine protect against, and how many doses are given?

• A. Influenza virus (2 doses) via nasal spray
• B. Rotavirus (3 doses) Oral live vaccine
• C. Poliovirus (4 doses) Given IM or subcutaneous
• D. Poliovirus (2 doses) Oral only

Answer: (C)

The key idea is recognizing what IPV protects against and how many doses it requires. The Inactivated Poliovirus Vaccine guards against poliovirus infections that can cause polio, and it is given in four doses. It is administered by injection, usually into the muscle. The four-dose schedule (often given in early childhood with a booster later) matches standard immunization practice. The other options mix up the disease, the type of vaccine (live vs inactivated), the route, or the number of doses, so they don’t fit IPV.
