This Short Animation Explains Beautifully How Herd Immunity Works
Show this to anyone who asks why they need to get vaccinated.

One of the most common questions you'll hear from people who don't want to get vaccinated is: "But if the people around me are vaccinated, why does it matter?"

And the answer isn't entirely straightforward, because both the reason this person needs to get vaccinated, and the reason they feel they don't have to, come down to the same thing - something called 'herd immunity'.

But now very talented Reddit user theotheredmund has created this animation that beautifully breaks down herd immunity in about 20 seconds. And it's the perfect thing to share in response to anyone who ever asks you again why they or their kids need to get vaccinated.

The short answer: it's not about you, it's about vulnerable people that can't get vaccinated, like newborn babies, or people going through chemo.
