Also there's substantial proof COVID19 antibodies don't last forever, in some cases only a few months. This article is riddled with questions.

  No. All recent data points to long-lasting immunity. A normal, gradual decline in antibody response is coupled with longer-lasting B- and T-cell response. https://threadreaderapp.com/thread/1285618977654407169.html https://threadreaderapp.com/thread/1285618977654407169.html https://www.medrxiv.org/content/10.1101/2020.07.14.20151126v1 https://www.medrxiv.org/content/10.1101/2020.07.14.20151126v...

    How does that explain repeat illness (not via testing but someone that is in hospital once month and back the next?)
    • timr 6y ago
      To date, there has been one documented case of re-infection. From everything we know, this very rare. There are many reasons a person with a severe illness might have to return to a hospital (e.g. lung damage from ventilators), but this has no relationship to repeated infection from the same virus.
