Anyone know if this accounts for natural immunity from previous infection?

It doesn't appear to do so. The problem with comparing natural immunity is that the COVID infections murder the weakest victims so the culled populations will tend to be more resistant than vaccinated populations.

But the overwhelming majority of people who have been infected, even those with multiple comorbidities, have fully recovered from their infections.

But in general you’re describing the longstanding concept of herd immunity.

My point is that herd immunity can be achieved using vaccinations at a far lower cost in money and in heartache. No matter how much you try to dismiss the downsides of COVID, the fact is that the downsides of the vaccination are even lower. From a cost-benefit analysis, there is no evidence that vaccination is bad public policy if you value human lives and the reduction in overall sickness.

"Herd immunity (also called herd effect, community immunity, population immunity, or mass immunity) is a form of indirect protection that applies only to contagious diseases. It occurs when a sufficient percentage of a population has become immune to an infection, whether through previous infections or vaccination, thereby reducing the likelihood of infection for individuals who lack immunity." -Wikipedia

Show me a covid-19 vaccine that can make me immune to infection. If a product doesn't provide that level of protection it can never be used to achieve herd immunity.

You cannot achieve herd immunity for this type of respiratory virus, with the current iteration of vaccines. I wish this wasn’t the case.

I have at no point downplayed the seriousness of covid. I just pointed out that your previous statement was objectively incorrect.

You didn't point out any facts that contradict my statement that COVID culls populations of the weakest persons, which is almost undeniable. You are simply arguing that COVID isn't killing enough people.

You implied that since the weakest among us are “murdered” by covid, the remaining population is more resilient.

I pointed out that the majority of “weak” individuals do recover. I explained that you’re describing a process of natural herd immunity that has existed long before vaccines were invented.

You also incorrectly claimed that the current vaccines could induce herd immunity for this type of respiratory virus.

No one is on “team covid”. You’re just bothered by people having a less hyperbolic take on the issue.

You can have a population where infections happen with no vaccines and get herd immunity. You can use vaccines we have now, infections still happen, and get herd immunity from the natural immunity from infections except that fewer people will be severely affected and dead because we know the vaccines make death and serious illness less likely. It's wild that you think somehow herd immunity is impossible in a world with these vaccines, but it is inevitable in a world where these vaccines don't exist.

Even as spelled out in your comment, the vaccines do not induce herd immunity. They merely help to reduce death while herd immunity is being developed through natural infection.

Although you cannot qualify the efficacy of a vaccine simply by its ability to reduce severity of infection from the targeted pathogen. You need to look at all cause death over the long term.

First, yes, AFAIK herd immunity may very well require true immunity. Although I'm also thinking about the possibility of reducing infections by enough that the spread is just too slow to get through our quarantine strategies. In that case, vaccines don't need to provide full immunity.

Second, these vaccines are not and will not ever cause more deaths than covid. I'm not sure what you mean by looking at all causes of death.

Do you have any data to suggest that these vaccines effectively reduce the rates of transmission? If so, by what rate?

Secondly, are you suggesting that zero people who would fully recovered covid without vaccination, will suffer a death caused by an adverse event caused by these vaccines?

Do you know how many healthy people you need to vaccinate in order to statistically prevent a single covid death?

Your goal should be to NOT contract the deadly mutating highly transmissible virus.

The vast majority of people have already been exposed and developed some form of natural immunity, with or without the vaccines.

No one of an accomplished background in infectious diseases would suggest that avoiding the virus altogether is a realistic strategy.

For Covid, infection-generated immunity wanes over time just as vaccine-induced immunity does. Regardless of what taught a person's immune system to recognize and fight SARS-CoV-2, it doesn't last. This has not only been documented from many data sources from many countries (ex nejm.org/doi/full/10.1056/NEJMoa2118946 ) it's also apparent in anyone's personal life. I think at this point we all know someone who's gotten covid multiple times.

It's also clear that avoiding infection is important not just to avoid death, but to avoid the negative health effects of multiple bouts of covid. nature.com/articles/s41591-022-02051-3

I’ve never suggested that natural immunity doesn’t wane over time - although it does offer a more broad and durable immunity, meaning if you are exposed to subsequent variants, your immune response has a greater chance at offering protection, and your immune memory can be updated to recognize the contemporary variants in circulation.

Even if your immunity wanes, your lingering immune memory will allow your body to mount a more targeted immune response when compared to a first exposure to a novel virus.

We’re not talking about blocking infection. We’re talking about reducing death and serious illness.

You can attempt to avoid infection, although it’s unrealistic to effectively prevent while living a normal healthy life. Your best bet is to maximize your natural immune health, and focus on protecting the most vulnerable in society.

This article has absolutely nothing to do whether you contracted the disease and it’s effect on transmission.
