I have no interest in this discussion and won't post more unless it's straight information. However what I will say is that there are a very many cases of false positives as well as situations where iiuc people are still testing positive well after it's gone for a variety of reasons. there are recommendations to irigate your nose before getting retested and it supposedly helps a little.
That being said I can try to get exact information in these cases and present the facts when they were tested , where they were tested. what type of tests etc. Supposedly these three cases were positive around pesach and are positive again now.
Please do get that information

Politics. Same reason Israel reneged on closing shuls for Yom Kippur.

This whole line of argument is absurd. You specifically, and many people collectively have argued against the need for restrictions at every turn.

How would you have felt to have constant sheriff presence outside every shul, school, and wedding hall for 2 months? You would have screamed "herd immunity" and government overreach.

The city tried it your way, but unfortunately, the facts no longer bear out that there's herd immunity. So I'm really at a loss for what you would have wanted to have been done differently.
When did I once say herd immunity?

The city tried what? They marched into Williamsburg with cops and sheriffs months ago and started writing tickets to anyone not wearing a mask when there were 30k people in Brooklyn square protesting without masks.

They could have worked with the leaders in trying to compel people to work with contact tracers. Instead they are coming way after they knew there was a problem and screaming for lockdowns. Also Williamsburg with a 1.67 positivity rate was included, the city of Buffalo had a 5.5 percent rate 3 weeks ago and we didnt hear a peep. There is a problem yes, but we are only hearing about it because the Jews are an easy target.

Im not gonna comment as to wether our fellow yidden are right or wrong because nothing seems to be able to change your mind about how terrible they all are.

So at this point, the question is not whether reinfection is possible. The question is  why.

Options could be:

- multiple strains
- everyone's antibodies are waning, but some people's are faster than others
- it's highly improbable, and collectively, there's nothing to worry about

Are you insinuating that they are being maliciously misleading? Highly unlikely
No; it just irks me how they seem to pick and choose which parts of medical science they rely on.

I also wonder what the affect of donating plasma has on antibodies. Have there any studies been done?

Completely a theory, but perhaps IgG antibodies may be reduced due to donations? But remaining T-cells would mean a mild reinfection like we have seen?

A medical professional friend who had covid didn't want to donate plasma for this very reason.

I've heard the same question from multiple Doctors.

A positive followed by a negative, with antibodies and then positive again would be very alarming.


The science on antibodies has always been that they could start to wane at 6 months, and that's right where we are, so while this is bad, it really shouldn't shock anyone.

If waning antibodies are the reason were seeing a second wave now, then this is pretty concerning.

I don't think plasma donations is the answer, though it's certainly possible.

T cells is fine for the person who has it, but probably does nothing to prevent the spread to others, which means herd immunity is that much harder to achieve. I've also heard theories that for some, getting the virus a second time could be worse due to underlying toll it took on the body the first time. So there may be a mixed bag here.

As the risks associated with reinfections are rising, there doesn't seem to be much justification for people who had it to not take any precautions.

Yeah the only not terrible reason here is statistical anomaly, or noise that people who recovered still have some matter that shows up on PCR inconsistently.

Not sure if that changes anything, it depends on how the state publishes its testing data. They can tell if a test is on a previously positive person. However anyone who never tested  the first time they got infected could in fact lower the rates no matter how the state publishes their testing data.

Because this would go against the Igud's approach. Every letter they've put out has urged people to get tested for antibodies.

If they currently test positive for antibodies, they are still presumptively immune, no? The reinfections seem to be people that lost their antibodies (which we know happened to a significant percentage of previously infected people, although we do not know what the likelihood of reinfection is after losing antibodies). Knowledge of currently having antibodies would still seem to be edifying, no?

Good point, except they are just saying "make sure that you had a positive antibody test". Not that anyone should get retested.

That should change if they are worried about reinfections
Workflowy. You won't know what you're missing until you try it.

A nice sized yeshiva in Brooklyn did an antibody testing drive on Friday for all members of yeshiva and mispallelim, and instructed everyone to take the test, even those that previously taken antibody tests. They seemed to want it for their in house policy formation. Could be more places will do this.

Depends. It's not known the levels of antibodies needed to show as a positive, vs the levels to fight off reinfection.

On the flip side (I wondered a while ago...)- someone with Antibodies that gets exposed to the virus, does that restrengthen the Antibodies? Did anyone out there who tested for antibodies 3 months+ ago retest? Are we seeing drastically different results?

Relative had symptoms Pesach time; tested negative for antibodies late July; just tested positive for antibodies this past week. (Lakewood).

Though that could be just flaky antibody testing.
