Reinfection is not rare, Singapore has detected 26 cases of reinfection so far: https://www.straitstimes.com/singapore/politics/parliament-2... Also note worthy: recent infections in Singapore includes "56 cases involving people who were infected despite being fully vaccinated"

Reinfection is very rare. The Israeli study is the most reliable, but going by your data point of 26 cases of reinfection and the ~61,000 cases[0] in Singapore, we're talking 1 in 2,500. 0 https://ourworldindata.org/explorers/coronavirus-data-explor...

But that statistic is useless on its own. The more salient statistic is "how much lower was the infection rate among people who have recovered, compared to people who had never had COVID, for the same time frame?".

It's moronic to get the vaccine if you've recovered from COVID. The reinfection rate is 1 in 1,000, and even then it's all mild cases. ( https://www.medrxiv.org/content/10.1101/2021.03.06.21253051v... )

Here's a counterpoint by an immunologist: https://theconversation.com/why-you-should-get-a-covid-19-va...

"The COVID–19 vaccines...offer a...more reliable means of protection than natural immunity."

This is false. She even goes on to say "Pfizer vaccine blocked 90% of infections after both doses" but we're seeing 99.9%+ protection from natural immunity.

She also doesn't put her logic on git (not surprising). If she had built a simple spreadsheet with the important data she'd realize her mistakes (assuming good faith).

I agree with your points, but I'd really really like to avoid giving the impression of... glee? "Look at those unwashed unvaccinated Trump supporters, so good they'll be forced to do things our ways now!". I'm not saying you're doing it, I'm just piggybacking on your comment. I'm pretty much a high-modernist when it comes to vaccines - I think that having governments build sewage and create vaccines go into the same…

This is getting stupid, if it wasn't already. Requiring vaccination is "curtailing liberties". Restricting movement due not being vaccinated is "curtailing liberties". No shit. One can either be part of society or not. Society has minimum requirements if one wants to participate. One is free—exercise their liberty—to live as a hermit if they don't want to do either of these things. That's the price of admission of ge…

In my country shitting on sidewalks, had higher priority than health or liberties. Dog walking was allowed, while exercise and outdoor activities were prohibited.

Society already excludes many people due to expensive housing, education etc... Living as hermit in a van is not that bad. But society should not expect taxes from excluded people :)

Wow. Thank you for sharing #2. "Yes, you should be vaccinated regardless of whether you already had COVID-19. That’s because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19." This is downright false. Someone should seriously sue the CDC. I don't understand how they can get away with this anti science, anti math, illogerate bullsh*t. We know far more about the…

I've been tracking information on COVID related immunity as my parents are due second dose, I'm due first dose and we're all COVID +ve (India). My parents got infected after ~ 30days of first dose Astrazenica, I got from them immediately. I had COVID brain fog, they didn't face much symptoms(vaccine doing it's job?). Luckily we all seem to be recovering well. Now since we've got immunity and that evidence suggests th…

I have seen an overwhelming amount of evidence that if you've recovered you are safe. I have been tracking this since early February 2020. I think if you've recovered you can stop worrying about COVID, and I have seen nothing that makes me think the vaccine is worth it in the least if you've recovered.

I would not worry about mutant strains either. It's a very genetically stable virus. Even though the numbers in India now are high, they are still significantly lower per capita than they were in the USA and UK last year. https://ourworldindata.org/explorers/coronavirus-data-explor...

It's not deadly to the vaccinated. That's the whole point of the vaccines. Or are you arguing that the vaccines don't work?

Vaccines work - but they are not 100% effective. If an unvaccinated, COVID positive person comes in close contact with 100 people that are vaccinated, a number of them will get sick. Way less than had they not been vaccinated. But way more than is acceptable.

> But way more than is acceptable.

Is it? Far fewer of them still will get severe symptoms. And this of course requires the unvaccinated person to actually be infected. From what I read, my risk (of at least an unpleasant time) is worse if that person had some other virus instead, since I'm much more likely to catch it and guaranteed to have unpleasant symptoms if so. At some point there needs to be a cutoff in risk level where it's low enough for a free society.

A bigger concern in my mind is that as long as the virus is spreading it is mutating, potentially becoming dangerous again to the vaccinated too. But this seems to be increasingly not likely with this particular category of viruses.

The paper you cited looks at re-infection at up to 100 days. She cites a paper indicating up to 5% of people have no signs of immunity at 6 months:

That you haven't met someone who can't take vaccines is not a reason to dismiss them. Intuitively, such people may prefer to stay in self-quarantine to protect themselves, making you even less likely to encounter such a person during a pandemic.

However, getting vaccinated should also help reduce the transmission of the disease to people who haven't yet had a chance to get a vaccination even though they could; the pandemic will end faster than if you let it run its natural course.

Thus limiting those that are not vaccinated and making it difficult to move freely for them. The travel pass is a horrible idea, that effectively will force many to be vaccinated. That should not be the european way.

Except that the people who are worried can simply get vaccinated themselves.

There may be a few people who can not be vaccinated (old and very sick), but it hardly seems appropriate to restrict billions of people just to protect those few. It would be more efficient to isolate them, which most of them probably already are (in care homes or hospitals).

For any vaccine (and the corresponding disease) there are people that cannot be vaccinated, but that can have quite severe symptoms (and/or die). If a person is not vaccinated - then this person can spread the disease among those vulnerable people. How this can be problematic - here is an example. One of the reasons Sweden has so high mortality from COVID is that during the first wave elderly care homes were hit hard, because workers spread the virus (mostly unknowingly). That you have not met such people in the last 6 months depends, I guess, on your social interactions style and on the structure of the society you live in in general.
