That's the term, & the thinking behind it is explained via Google dictionary as follows: "the resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease, especially through vaccination."

i hope the said population cull takes some of these confessioners with it. its so hard to tell what sort of stance they want us to take against them.

Googling herd immunity

Also you might be surprised to hear that "who cares about the kid who isn't vaccinated" is not a moral position shared by the rest of society. Just like "who cares about the kid who is being abused" is not something that a moral person would say.

Google is your friend.

... get vaccinations. disgusting. My proteins are holy.

You just made yourself sound dumb. Too bad there is no vaccine against stupidity.

There are some people who do not have the choice to be vaccinated due to other health conditions. They rely on the pepple with the choice to make the smart one.

I am old enough to remember people walking aroind that were a stark reminder of what polio could do to a human body. That, in and of itself, is reason enough to choose vaccination.

What does "save the planet" mean in this context?

The planet has no need of humans, or any life at all, for that matter.

I was also curious about this. Seems no vaccine is 100% effective so there will be a portion of the population that will be susceptible during an outbreak. Also elderly and babies are vulnerable, babies can't be vaccinated until 3 months and require a series of shots during the first year. So not vaccinating your kids puts other people at risk because it increases the chance of an outbreak.

The reason ppl worry about some kids' parents choosing not to vaccinate their children is because some kids are too sick to receive vaccines and so long as there are kids who can potentially become infected, there is a risk to those who don't have the option of being vaccinated.
