You could write a Shakespearean analogy. They dont care, their beliefs outweigh the truth.That's true, but the vaccinated majority are less likely to a) suffer symptoms from it, b) spread it to others that would suffer from it. The more vaccinated people you have, the greater herd immunity.
Just run with me on an analogy, it won't be a perfect analogy but the principles are the same.
Imagine I have some fire-resistant paint, that reduced the risk of trees catching fire by 70%. Say there was a forest fire and it started at one side and was spreading the other. On the side that it was spreading towards, I'd painted 15 rows of trees in the middle, effectively as block aid, to stop it spreading to the other side. Some of those trees that are painted will still burn, but a significant proportion of them won't. The fire eventually runs out of suitable hosts, and is far less likely get to the vulnerable trees on the other side.
It is never going to be a perfect analogue, but it shows the purpose.
