Quizplus · Accepted Answer

Herd immunity requires a high percentage of the population to be vaccinated in order to prevent the spread of infectious diseases. The exact percentage required may vary depending on the contagiousness of the disease, but experts generally agree that a vaccination rate of at least 80% is needed to achieve herd immunity. Choice C (80%) is therefore the best answer. Choices A and B are too low, while choices D and E may be unnecessarily high for some diseases.
