This may be a dumb question...I am not a scientist.
If this magical herd immunity is obtained (which will result in several million deaths), am I correct in saying that herd immunity is weakened or incrementally diluted each time a person is born, or each time an immune person dies from a non-Covid related cause? In other words, herd immunity might not last forever because people are born that are not immune, and people that are immune die?
Or rather, is the virus considered to be starved to death once herd immunity is achieved?
Also, if herd immunity is established in the US, what happens when tens of thousands of travelers from other countries come here for whatever reason, and they do not have herd immunity? Wouldn't that start the Covid ball rolling again?
Thanks in advance.

(17,450 posts)in general, are virus mutations generally more virulent from what they mutated from, or less virulent?
I have no idea...just trying to gain some knowledge.

The idiot actually spewed the term "herd mentality" last night in the ABC town hall because apparently his addled brain couldn't come up with "herd immunity".

Common colds are a type of Corona virus and there's no effective herd immunity and there's no vacccine. It's possible COVID-19 may be similar...and much more deadly.

(7,433 posts)herd immunity has actually occurred. So Trump and his band of killers want to kill millions just to see if herd immunity has teeth. And besides, it's a lazy way to execute policy while it's an easy way to kill off millions.
What we DO know is that variables can interrupt any useful field experiments. Let's think of just one: anti-body shifts. What we do know is that anti-body defenses against COVID-19 are NOT permanent. Anti-body defenses do weaken, and a once well-defended human can become vulnerable over the course of time. Without a vaccine, people can become vulnerable again and again, just like the flu. So "herd immunity", based upon just this one factor, can never be achieved.

(58,676 posts)In some respects, Europeans developed what you could call "herd immunity" to smallpox. It was still deadly, and could spread rapidly, but by the 17th Century or so, it was what you could call manageable. Meanwhile, in the 15th-18 Centuries the European incursion in North America led to untold millions of deaths throughout native populations, largely due to diseases like smallpox.
By the 19th Century, people had learned lessons of isolation and sanitation that could slow the spread of smallpox and other contagions, but it wasn't really 'eradicated' until vaccines were developed in the 20th Century.
"Herd immunity" basically means you determine an acceptable level of infection and death and live with it. Most civilized countries find that unacceptable.
