a: herd immunity ~
b: moat around a castle

What:

"The idea of herd immunity is like a moat around a castle or the natural behavior of herd animals when threatened by a predator. The strong surround the weak to protect them from attack; in this case the vaccinated protect those who can't be vaccinated or those with low immunity from contact with the flu by halting the spread of the virus."

"Herd immunity" is like what makes it hard to learn Chinese in a town where very few people are learning Chinese. There are few tutors. The second hand bookshops don't have cheap beginners textbooks. You don't hear Chinese on the radio or TV.
