In the state of Indiana, 199 out of 200 COVID deaths are unvaccinated adults, so that blows the study away.

In what way does it do that? The study says those that those that fully recover from covid have a stronger immunity than those that have been vaccinated. How many of the 199 unvaccinated in Indiana previously recovered from Covid ? If not more than one, then the results in Indiana would at least indicate that those that recover may well have no less immunity than the vaccinated which would somewhat reinforce the findings of the study.

There’s still a lot of debate about how representative the Israeli experience is. The rush to do boosters is supported by that, but there’s other evidence that’s not so clear, so not everyone agrees. There’s at least some suggestion in that reference that Moderna may do better against Delta than Pfizer, but not all results say that.

It seems some people here may be misunderstanding what the authors of this study are concluding from their results. They are definitely not concluding that people should not get vaccinated. If the study is correct, the one thing we can say is that only the fully recovered should consider that they would be as safe as the vaccinated from the Delta variant. As the vaccinated are not 100% safe, the fully recovered are not either.

I've said it before, the flaw with this reasoning is that it's a all or nothing approach. Caccines help protect you against the virus, if you THEN catch it later your body will more readily fight it off, and even if natural immunity is better due to the nature of the MRNA vaccines, you will get the natural one later. Think of it as the vaccine keeps you alive till you can get natural immunity.

Just have to look at the rates of people in the hospital in most places.

Politicizing an issue causes people to ignore anything that doesn't stick absolutely strictly to the party line. Those that want to see vaccines as evil will find nothing about them that might be positive and those that want to use vaccination as a requisite for being allowed to participate in society at all will find evil in the intent of anyone that says there is even a possibility that some people might be no more harmful to society than those that have been vaccinated. Ideologues believe what they believe and therefore only the data that supports their belief will be considered. All contradictory data will be ignored.

A new study out of Israel has seemingly confirmed that individuals who have natural immunity have better protection against the NEW DELTA VARIANT than people who are fully vaccinated.

Conclusions: This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity. Individuals who were both previously infected with SARS-CoV-2 and given a single dose of the vaccine gained additional protection against the Delta variant.

What are you thinking?

You are not making sense. What are you proposing?

Get sick with an older version of COVID? Are you going to find vials containing the original virus and snort it until you get sick? These types of posts show the complete lack of logic in anti-vaccine proponents.

See, if you get sick with COVID, you'll have better immunity with COVID than with a vaccine. Which accomplishes what??? So I can get a vaccine and have a great chance of not getting COVID, especially if EVERYONE gets it. Or I can get COVID and have a better chance of not getting COVID.

What it does indicate, if it proves to be valid and reliable, is that those that already had Covid and fully recovered ought to be treated with in at least the same regard as those that have been vaccinated whether they get vaccinated or not.

That's how it works. Pretty much the way influenza works. The vaccination does better.

Thanks for the site but it doesn't negate my post, which is about COVID deaths. Natural immunity hasn't helped most people who die, in the US. My info came from the Indiana Public Health Dept., which said 199 out of every 200 COVID deaths in Indiana were unvaccinated adults.

I don't care how many had had COVID. Why would someone risk dying from a disease when a simple vaccine would have saved them from dying?

If , as the Israeli study suggests, a fully recovered person is at least as protected against Covid as the vaccinated person then that fully recovered person would not be taking a risk by not being vaccinated. So knowing how many of the Indiana 199 unvaccinated had previously recovered from Covid would be an important statistic if one was going to try to refute the Israeli study. If 198 of that 199 were not preciously infected then, of the full 200 in the group, the results for the fully recovered would be exactly the same as the results for the vaccinated. If a few more than 1 fully recovered and unvaccinated person were found in the group it would tend to contradict the Israeli study. Without the full picture I cannot say whether the Indiana numbers make any difference or not in relation to confirming or refuting Israeli study.

Apparently, that study hasn't been reproduced by others. And now, it appears that the mRNA vaccines do a much better job of protecting one against new variants, than natural immunity:

In the P.1 strain originating in Brazil, one study found antibody effectiveness six times weaker against the P.1 in comparison with the original SARS-CoV-2 strains. That study estimated that 25% to 61% of previously infected patients were susceptible to P.1 infection.

Similar issues have been found with the South African variant, also known as B.1.351. A vaccine trial for Novavax found that participants in the control group who were previously infected were just as likely to become ill with B.1.351 as those without natural antibodies, suggesting older strains of COVID-19 failed to provide immunity against B.1.351. By comparison, the vaccine did offer some protection.

Vaccines seem to be more consistent in dealing with mutant strains.

There are some important differences in immunity acquired via an mRNA vaccine vs. natural immunity that suggest vaccines may provide more consistent protection against the various mutations of COVID-19, according to a study released in June by the National Institute of Health.

The study looked specifically at on the receptor binding domain (RBD), a key region of the spike protein on the outer surface of SARS-CoV-2. It found “antibodies generated by the mRNA vaccine were more focused to the RBD compared to antibodies elicited by an infection, which more often targeted other portions of the spike protein. Importantly, the vaccine-elicited antibodies targeted a broader range of places on the RBD than those elicited by natural infection,” the NIH said.

“These findings suggest that natural immunity and vaccine-generated immunity to SARS-CoV-2 will differ in how they recognize new viral variants. What’s more, antibodies acquired with the help of a vaccine may be more likely to target new SARS-CoV-2 variants potently, even when the variants carry new mutations in the RBD,” the NIH said.

So you have conflicting results and conclusions from different studies taken in different places with different strains. Which mostly tells us we still don't understand the virus well enough to be confident we are going to be able to control it. Which seems to be reinforced by the case surges we are seeing in the real world that are not limited to those that have never had Covid or those that are unvaccinated. Both of the groups that have had Covid or been vaccinated do seem to be better off if infected than the never had never vaccinated group. The question of which of the two better off groups is better protected against any particular strain of this virus is something I am not convinced we can be sure of. However, if it was me and I had had Covid before I would get vaccinated anyway . I do not see that there is any greater risk of a bad outcome from vaccination due to already having had Covid than there is risk for those that have not had Covid. My uneducated guess would be that , having already survived the real thing one would probably be less likely to encounter a bad outcome from the vaccine.

Ya think? This is why it's supremely foolish to hope that natural immunity might be a good alternative. Even this early, we know that even a mild infection often produces lasting damage to one's health.

It has merely shown us that the vast majority of those in the surges are the unvaccinated, while the vaccinated are much less likely to become infected and much, much less likely to become severely ill.

WASHINGTON -- This summer’s coronavirus resurgence has been labeled a “pandemic of the unvaccinated” by government officials from President Joe Biden on down.

The sound bite captures the glaring reality that unvaccinated people overwhelmingly account for new cases and serious infections, with a recent study of government data showing that hospitalization rates among unvaccinated adults were 17 times higher than among those fully vaccinated.

It's possible to make an educated guess. There is data out there. As early as last November, that kind of patient started turning up:
Severe, Symptomatic Reinfection in a Patient with COVID-19 - PubMed

By this August:

Cases of reinfection with COVID-19 have been reported, but remain rare.

In general, reinfection means a person was infected (got sick) once, recovered, and then later became infected again. Based on what we know from similar viruses, some reinfections are expected. We are still learning more about COVID-19.
COVID-19 and Your Health

My thought is that an infection serves the same purpose as the initial does of the vaccine. A second, immunizing does is what provides more lasting immunity. I would expect a person who has recovered from the virus would get very good immunity from a single dose of the vaccine, much better than was obtained by recovering from a single infection of the virus.

What hasn't been discussed is the fact that natural immunity also wanes with time. Thus making future boosters more effective than natural immunity. Until the unvaccinated get infected and spread the disease again, then they will have stronger immunity again until the vaccinated get their next dose.

And of course the vaccinated that also survive infection get the best of both worlds.

We haven't even had this vaccine for a year, and we haven't had time for any studies about natural immunity for the majority. You always have some that it won't do much, or goes away quickly. I think we need to wait on more data - since it hasn't been a year yet. Besides the government never mentions anything about natural immunity, because they want to you to get the jab anyway. Will it help or hinder? We don't know. They just want you to get the jab anyway.

According to Biden 3/4 of Americans had the vaccine. The numbers seem to go up everyday. This SHOULD be good news. Although you would never know it.

He said due to that among the vaccinated the risk of being infected: fully vaccinated, your risk of severe illness from Covid-19 is very low. In fact, based on available data from the summer, only one out of every 160,000 fully vaccinated Americans was hospitalized for Covid per day.

This is also good news - or least it should be. It means for the vast majority of us we are already protected.

Yet, Biden also says: We’re going to protect vaccinated workers from unvaccinated co-workers. That's confusing. Its basically saying you aren't protected even if you are vaccinated. lol so even if we FORCE people to get the jab? No one is going to be safe anyway. Wow. Great incentive for the non-vaccine people to get the jab. (eye rolls) The messaging in this circumstance really rots.

He said the unvaccinated people costed us. The only way they cost us is if the vaccine isn't what it is cracked up to be. On the one hand he said our cases are VERY LOW, and then he says we need protection from them. Biden Quote again: I understand the anxiety about getting a breakthrough case. But as the science makes clear, if you’re fully vaccinated, you’re highly protected from severe illness even if you get Covid-19.

So why are they encouraging this much anxiety and pushing all this junk he spoke about if majority if the nation is already protected? Different Quote: In fact, recent data indicates there’s only one confirmed positive case per 5,000 fully vaccinated Americans per day. You’re as safe as possible, and we’re doing everything we can to keep it that way — keep it that way and keep you safe.

Are we as SAFE AS POSSIBLE? I have no idea. First you have 1 in 160,000 of being hospitalized, and then 1 in 5000 of getting infected. Those numbers look good to me, but we need protection anyway.

He said among the kids that caught it? They were over 12. I'm sure that is just the majority since humans aren't absolute. No doubt that is why over 12 they encourage the shot. lol because even if you are vaccinated your kid over 12 you need protection from. Sigh.

Of those that aren't vaccinated? How many are under 12? How many have immunities? How many are medically not able to get one? I know we had a vendor here at our home, and he couldn't get it. He kept his distance (we are all vaccinated), and his household all are. His doctor says its NOT in the cards for him right now. He wants it too.

The government sincerely needs to hire some messaging people that know what they are doing. No doubt they think they are doing a good job, but it seems they are to distanced from the reality on the ground to really get it. It is called the belt way bubble for a reason.

Since we are suppose to approach politics with a cynical eye? Are they just distracting us from other things to keep the anxiety levels high so we don't notice? All politics do this. I don't care what flavor you like.

With 80 million Americans still unvaccinated, and even up to 20% of those vaccinated, still vulnerable (mRNA vaccines are observed to be roughly 80% effective against Delta), and endless waves of Americans dying, we still have much work to do. I personally don't mind the cynical approach, and I don't mind government taking a harder position on the unvaccinated. We still have over 1,000 Americans dying from covid every day. 15% of which are of a working age between 50-65 years old. Meaning that the virus is crippling our work force (though typically the unvaccinated as you had noted, but workforce Americans none the less).

We also have studies suggesting that vaccination is still beneficial for protection against Delta, even for people previously infected.




I think that people opposed to vaccination are more worried about government control than they are worried about vaccination itself these days. People are still denying that masks work despite masks capturing moisture on which coronavirus can travel. But I think that people are largely opposed to masks moreso out of concern over government control than over a legitimate argument against the use of masks.

Regarding natural immunity, I am a younger healthy individual and I had covid twice about 7 months apart. Thousands of repeat cases are being recorded nationwide as well, and as noted, we aren't even a single year in. I agree that more data will be needed as we approach a year, but currently it's not looking like natural immunity will last any more than a year or two, at least not without significantly dropping in percentage of protection.

And of course the virus could simply mutate again, in which case we would all be back at square 1 again.

"Besides the government never mentions anything about natural immunity, because they want to you to get the jab anyway."

And lastly, I think it's fair for people not to promote natural immunity, because it implies that the best course of action is to allow yourself to get infected. Which of course equates to more deaths and more spreading of the virus. If we promoted natural immunity, it might end up as promotion of things like "covid parties" where people intentionally go to get infected for immunity, or if a child gets covid at school, parents might want to bring their children together to intentionally spread the virus like we do for chicken pox. So I don't think promoting natural immunity is idea. Certainly not over vaccination. And if "getting the jab anyway" produces an even greater immunity, as noted in research, then it is the ideal position to promote.

3 / 4 of eligible people have at least one shot. With delta, you really need two. And epidemics don’t care who is eligible.* So you also need to look at the fact that 54% of the population is fully vaccinated. In 4 states it is 40%.

It is good news. When the DeSantis surge started killing hundreds of people daily in Florida, there was a sudden interest in getting vaccinated. Now, it appears that the surge might be abating as a result. At least deaths are starting to decline.

Part of it is that local governments and school districts are just ignoring the Governor's decrees to not protect their people, but much of it is because more people are immunized.
