Which statement best describes one reason herd immunity is important?

Explanation:
Herd immunity works by lowering the overall transmission of a disease in a population, so people who cannot be vaccinated or don’t respond well to vaccines are protected by the immunity of others. This indirect protection is why herd immunity matters—the immune individuals act as a barrier to spread, reducing risk for those who are not eligible for vaccination. It best describes that it protects those not eligible for vaccines. It does not guarantee lifelong immunity for everyone, and boosters may still be needed to maintain protection. It also benefits the unvaccinated, not just those who are vaccinated.
