Yeah I was gonna say, how many times in the past year did we hear "oh infections are down from the peak, we're approaching herd immunity" only for them to surge back up. Even if we really do hit the threshold this time (doubtful given the track record of assumptions about undetected cases), immune people die every day and non-immune people are born every day. If you're not vaccinating new people at herd immunity rates you drop below the threshold and outbreaks can spread again. That's just basic math, that's why diseases always came in waves and were never just "over" one day before mass vaccination.

Herd immunity has never been achieved for any disease in human history with natural infection or even a combination of vaccines and natural infection.

Smallpox was entirely a vaccination campaign, "natural immunity" had nothing to do with it.

The UN had teams that would go in anywhere a smallpox case was detected and vaccinate whole villages for miles around to snuff it out. They weren't like "well vaccinate some people then once enough other people get infected it will go away on its own" because that wouldn't have worked.

Rinderpest isn't a human disease, but I'm pretty sure the solution was mass vaccination and culling. I mean come on, livestock don't need to consent to vaccines in the first place, they just vaccinated them all, there weren't resistors.

Again those thresholds were achieved by vaccination, and maintained by vaccinating enough new kids every year. Not by vaccinating halfway up to the threshold and then going "ehhhh once everyone else gets measles mission accomplished"

There have been multiple measles outbreaks specifically in areas that stopped vaccinating enough kids because their parents were morons. "Natural immunity" has never cleared a disease, you vaccinate enough people and you keep vaccinating, or the disease comes back every year.

E: like this is a middle school algebra problem. If the herd immunity threshold is 90%, and you vaccinate 45% of the population and the other 45% get sick and get antibodies you hit herd immunity. Is the disease over now? Well what happens the next day? Old people with immunity die of old age, new babies are born without immunity, kids without immunity have birthdays and age up into vaccination age. How many of those kids do you have to vaccinate to maintain herd immunity? 90%. What happens if you only vaccinate 45% of them? You're not at herd immunity anymore.

"Herd immunity" does not mean the complete eradication of a disease. It means that if a disease is introduced into the environment, it will tend to not spread widely. We've achieved this for many, many diseases. Before modern medicine, this was how all diseases were "managed". Humanity would have never been able to build cities if every deadly disease since caveman times was simultaneously running rampant through the population all the time.

And even if you mean full eradication, we have done that with vaccines before.

:shh: its to hard for him to understand things that arent explained in the first paragraph of wikipedia.

Herd immunity exists, and we have experienced it with and without vaccines. Namely its been seen in the fact that we have controlled many pathogens to some extant even before modern times. However discounting it all as being vaccine driven ignores several aspects that have gone into this. Alongside this Vaccines are largely modern technology, with only smallpox being known as the most common early vaccine (hell vaccines come from the drat viral name) and actively the use of an attenuated virus was used in Arabic cultures probably back the the 1700s in order to immunize people, with it taking an actual massive fight for the European powers to consider that the arab savages (as they termed them) actually were correct and that the method of draining blood and pus from a patient was dumb. Chicken pox largely was the same way, most of us remember growing up and getting it, and it was common knowledge for who knows how long that having your kids get chicken pox early was beneficial in order to prevent deadly infections in the teens or adult ages. Measles largely was herd immunity until the vaccine, because it spread like goddamn wild fire and still does, more so then covid does because its an actual legit airborne virus that can and will spread to anyone that doesn't have some level of protection.

Herd immunity was a thing, and we normally associate it with viruses for a specific reason, vaccines made it so that it was much much easier, and more likely that people could safely and effectively be protected increasing the ability to protect an entire population instead of pockets of it around areas that had an outbreak prior. Again though, none of that matters to someone that is screaming doomerism from twitter to be an rear end in a top hat, and doesn't understand basic epidemiology because it cant be cut down to the information from a cracker jack prize toy

My bad, I just finished reading about that in one of my virology books again and goofed. Varrila was what I was thinking of and the cowpox verson that was identified as the major reason milkmaids were immune (and one of the other types of smallpox vaccines) was vaccinea the sub species that infected cows and only caused an extreme limited infection in humans.

Smallpox like polio is weird, there is no actual zoological reservoir like other viruses, it only infects humans and can't effectively cause any reaction in other species. It served as the main way we could eradicate it because once the last person was cured, that was it.

I'm sure plenty of countries will reach herd immunity though because they aren't filled with antivax morons. I just think the specific goalpost-moving everyone is doing to convince ourselves we'll reach it without vaccination is nonsense. Just like every prediction over the past year that it's "over" in Sweden or Brazil or Florida or wherever because we reached "herd immunity" turned out to be wrong.

Smallpox literally was in the middle east in many communities because of the intentional spread of mild forms of it, but that apparently doesn't fit with your mindset of having to be right and scream about how everyone's wrong. Alongside that Chicken pox again had no vaccine until the 1990s, and in many areas was fairly well contained and never truly spread because people would routinely be exposed even in earlier centuries to help prevent the deadly infections as people got older. Chickenpox is like measles and is an airborne pathogen, and spreads faster and more aggressively then covid, yet you never heard of entire regions suddenly coming down with it because of intentional spread by parents.

You literally do not understand a word of what you are trying to spout, herd immunity is much more then just an entire population of a country, or even state. Going back centuries you did not have vaccines, but instead an entire city or town would be immunized because of an infection or intentional infections, allowing those areas to be considered immune. Largely what your screeching is wrong, and is based on new age ideas that largely are due to the fact that we have GLOBAL TRAVEL, which makes it so that one person being sick can suddenly infect an area where no one has exposure, much like the Washington measles outbreaks where antivax morons ended up getting it due to an infection from someone not vaccinated and from an area it was present. It however did not end up spreading throughout the state, but instead stayed inside that community, because the surrounding areas were immunized.

I don't know why I am bothering though, you don't understand or want to understand epidemiology, or understand how it worked in past circumstances. You want to scream that we are all wrong and that you are right the world is ending. Take your cracker jack bullshit back to people that want to read it.

Edit: don't try to start spouting poo poo related to past plagues like typhoid or cholera, those were bacterial and the actual mechanisms of infection, spread, and evolution of bacteria are drastically different compared to viral pathogens. Even the bubonic plague wasn't a herd immunity, it instead slowly became less deadly because it actively and rapidly killed people off, along with other circumstances that are fairly specific to the hell of the dark ages.

through thousands of posts in D&D over a decade, I now believe I know what I'm talking about. if I post forcefully and confidently, I can convince others that is true. no one sees through my facade.
I think that fundamentally what people want from herd immunity is really variable. To epidemiologists, herd immunity is simply a natural function of disease resistance eventually driving the r to <1.0, and it's no real guarantee that any vulnerable populations will be protected. In the media it's a finish line where anti-vaxxers and immunodeficient people can go out as normal without assuming a level of risk. The former is quite viable and indeed is unavoidable, while the latter is unprecedented and very unlikely.

No. There are many factors that affect the course of epidemic (which is why NPIs are a thing). Herd immunity has a specific meaning, it is not a catch-all term for "things got better".

Since you handwaved "every disease" I'll help you out with a counterexample: cholera. It didn't go away because everyone got cholera and got natural immunity. It went away thanks to NPIs (specifically someone finally figured out you shouldn't poo poo in your own drinking water supply)

Absolutely not. Bubonic plague is spread to humans by an animal vector (fleas on rats), the concept of herd immunity in the human population doesn't even apply, for the same reason no one talks about reaching "herd immunity" from malaria or yellow fever. You can read about the debates over the various reasons bubonic plague declined because it's debated, but "natural herd immunity" isn't one of the theories.

I beg of you guys to learn the definition of terms like "herd immunity", it's been terribly misused and abused in the media so I get it.

Uhh it's not a strawman, someone posted a prediction that covid is almost over in Oregon because of natural immunity supplementing our inadequate vaccination rates. I'm skeptical of the specific claim, I think I told you that already because you seem very confused about what I'm saying or are strawmanning me yourself.

This isn't herd immunity this is just how endemic pathogens work. Almost all kids ended up catching chicken pox and new children would continually be exposed to it. That's not herd immunity at all since the population isn't able to protect the vulnerable group from infection.

Covid will likely be similar since it seems like delta would require well over 90% of the population to be immune.

Yeah, but that is literally the mechanism that stopped everyone on earth from having cholera 24/7 from birth and why cholera "outbreaks" are a thing instead of a constant steady state of everyone having cholera over and over perpetually.

It feels like you are treating "herd immunity' as the point a disease becomes extinct, instead of the mechanism by which recoverable diseases slowly find it harder and harder to find new hosts and eventually have the trend line of a disease point negative.

Like if a cold gets in your house everyone in your house gets that cold, it's inevitable, but then you don't all simply circulate that cold round robin forever until you all die. The population of your house reaches herd immunity, the household outbreak ends. Colds still exist, and another cold will surely eventually strike your home, but for that outbreak, you achieved herd immunity, the virus had no were left to spread and died out in that house. That is all it means.

We never reached herd immunity for cholera, cholera came around over and over in the same cities until we found the cause. Getting to "herd immunity" for cholera in a city like London would mean absolutely staggering amounts of death.

Yes if you reach herd immunity then the trendline of new cases will fall, because herd immunity is the point where the disease will burn out even if you do no NPI to control it. But just because the trendline falls doesn't mean you hit herd immunity because the trendline can fall for other reasons. The trendline of new infections fell several times in the USA over the past year, did we ever reach herd immunity?

No this is not herd immunity, this is just immunity. If everyone in your house gets the cold then you're all protected because you personally are all immune. Herd immunity is when unprotected people are mostly safe from getting it in the first place because enough people around them are immune that infections die off exponentially instead of spreading.

It really seems like you think herd immunity means the disease goes extinct. Literally it's just the statistical notion that if your whole house gets that cold and becomes immune that now your brother who you visit regularly is now less likely to get the disease because now the disease can't spread from someone to you to him. So there is one less route for it to get to him. It doesn't mean your brother is magically imbued with a mystic shield or that colds are gone forever. It's literally just the idea that as more people get a disease it's harder for the disease to spread more.

At last yes this is nearly correct. Herd immunity is not "the idea that as more people get a disease it's harder for it to spread more" but it is a logical consequence of that fact. The herd immunity threshold is the tipping point where outbreaks die out instead of spreading.

That is something that has only been achieved in the 20th century through vaccination. There was never a point before mass vaccination that a detected polio case wasn't a threat because of herd immunity, we never infected all the kids with polio and then polio epidemics were a thing of the past, when polio came to town it ripped through and put huge numbers of kids in the hospital and we did NPI like closing swimming pools etc, not "hey once 7 in 10 kids get it problem solved". The prediction that we're going to reach herd immunity on Oregon without vaccinating to the threshold is dubious imo.

Yes without a doubt. Was it because we reached herd immunity? Obviously not, because the trendline went back up over the summer right?
