What is herd immunity and why is it important?
What will be an ideal response?
Answer: Herd immunity occurs when more than 90% of people in a community are fully vaccinated against a disease, leaving that disease with little ability to spread through the population. It is important because it offers protection to people who cannot be vaccinated or who have not been vaccinated yet.
