Identify the typical advantages of live attenuated vaccines: They often provide long-lasting immunity, can mimic a natural infection, and sometimes can be administered orally.
Consider the statement 'They require multiple booster shots': Live attenuated vaccines usually do not require multiple booster shots because they tend to provide long-lasting immunity with just one or two doses.
Evaluate each option: Compare the typical characteristics of live attenuated vaccines with the options provided to determine which one does not align with the known advantages.
