Which of the following is an example of an inactivated vaccine?

• A. Measles, Mumps, Rubella (MMR) vaccine
• B. Polio vaccine (IPV)
• C. Yellow fever vaccine
• D. Human Papillomavirus (HPV) vaccine

Answer: (B)

The polio vaccine (IPV) is classified as an inactivated vaccine because it is made from virus particles that have been killed or inactivated so they cannot cause disease. This method helps stimulate an immune response without the risk associated with live pathogens. Inactivated vaccines, like the IPV, often require multiple doses to achieve long-lasting immunity, which is a routine aspect of their administration schedule. In contrast, some other vaccines, such as the Measles, Mumps, Rubella (MMR) vaccine and the Yellow fever vaccine, are examples of live attenuated vaccines. These contain weakened forms of the virus that can still replicate in the body, generating an immune response without causing the disease itself. The HPV vaccine can vary in formulation, but some types utilize a recombinant method rather than the inactivation of a whole virus. Understanding the difference between vaccine types is crucial for effective immunization practices, as it affects not only the immune response but also the scheduling and potential reactions associated with vaccination.
