Give me evidence (not Wyttenfact) that the RECOVERY dose was anywhere near LD50 for a one-off dose. And, preferably, think before you type.
Should this be try to rescue your nonsense THH FUD? They didn't give only one-off dose. they gave it for 5 days! Half live of HCQ is weeks
Here the printout of the Drugs database! I hope you can convert mols to liter. One hint: Blood is almost water...
The LD50 values for chloroquine were 24.77 μM (RAW 264.7) and 24.86 μM (BMDM), the LD50 for hydroxychloroquine were 13.28 μM (RAW 264.7) and 13.98 μM (BMDM). In conclusion, hydroxychloroquine was more cytotoxic than its parent molecule. Comparing the two cell types tested, our data suggest that there are no differences in cytotoxicity of chloroquine or hydroxychloroquine for primary cells (BMDM) or immortalized cell line (RAW 264.7).
Following a 200mg oral dose, hydroxychloroquine reached a Cmax of 129.6ng/mL with a Tmax of 3.26h in the blood and a Cmax of 50.3ng/mL with a Tmax of 3.74h in the plasma.13 Following 155mg and 310mg intravenous doses, Cmax in the blood ranged from 1161-2436ng/mL with an average of 1918ng/mL
If they gave it intravenous as reported 2 grams then they crossed the LD50 barrier way high!
There is 200 dead more than a normal year due to HCQ this spring in USA and at the same time there was about 1 million extra prescriptions of HCQ or so. This means that if all people take HCQ we are talking about around 200x350 > 60 000 dead.
Taking HCQ without control is a disparate action. Even when my friend got it I did not recommend to use it! But I would not trust any death statistics form the USA as there certainly is some bias today.
HCQ has been taken by more than 2 billion people on planet earth some 100 million take it regularly. Just compare it to deaths from Aspirin and you will see it's lower!
In addition, when we talk about immunity, we probably mean partial immunity. A small dose infection might be fought off, when a larger dose would not be so.
This is true: Cross immunity is always partial and a high dose will make you sick too. But people with cross immunity will show no antibodies even after a mild infection. This makes it awfully complicated to track the spread of this disease. So all your cases 2,3,4 have a partial immunity.
There is a fifth built in cellular immunity that we did not mention yet: RNA inference can detect all unfriendly rna junks if the target junk is stored in the cellular database (genom). The result of this process is that the virus is only partially rebuilt as the "rna police" always cuts some pieces out to inactivate the checked rna sequence. But in the worst case this could be a gain mutation...
