Sweden's government is to the COVID-19 pandemic what South Africa's (Mbeki) government was to the AIDS pandemic

They ditched mainstream, evidence-based advice.
So their people died

Finding T cells with (supposed) seronegativity is an issue when:

1) Antibody test's sensitivity isn't stated

2) COVID-19 often involves pathological, immune-mediated cytokine storm

Re: "1) Antibody test's sensitivity isn't stated"

So if sensitivity is low, many of their seronegatives are false negatives. That's especially an issue if their studied population's proportion of true seronegatives was also low.

Re: "2)"

So finding T cells doesn't entail Sweden was closer to herd immunity, despite what's said by some non-experts who distort medical science to justifying their ideological opposition to lockdowns

An illustration of the point that finding no antibodies can be due to one's test having low sensitivity, not a lack of antibodies:

Another illustration of the point (h/t to @EuphoricEuler):

Re: "(supposed) seronegativity"

Studies with smaller sizes, showing antibodies either not appearing in some patients and/or falling beneath limit of detection by ~3 months:

https://www.biorxiv.org/content/10.1101/2020.07.16.206847v1.full.pdf

Large study showing otherwise:

Re: "Antibody test's sensitivity isn't stated"

A great thread giving some ore context on this, except less focus on test sensitivity and more focused on the immunology 101 behind natural drops in antibody levels (that don't fall below limits of detectio)
