Has there been a single reinfection of someone who currently had IgG antibodies at time of infection?
My issue is, most of the stuff is based on what we know and a lot of what we don't know and so much of what we know is that we don't know.
It's like me, I know I don't know tur, shach, taz, bach, aruch hashulchan etc so I know I can't give a halachik analysis.
Do we know if people can be reinfected ? Not really, it's true that very few did.
Did that take into account decreased antibodies? Dunno
What about the fact that the people who were not reinfected during the time there was no new cases? Maybe it's because they simply weren't exposed to the virus.
My issue is, people just making things up.. is there a possibility that somebody can get reinfected and because nobody's taking any precautions because they had it already. They could then spread it ?
