1) How are you defining more dangerous? More kids (18 and under) have died of covid over the last 18 months than those who've died of the flu over the last three years. But whatever, the total death rate is minimal in comparison to the adult population. But let's keep going. Let's say you're right, covid is less dangerous. Is it 5% less dangerous? 10%? Where do you draw the line?
2) Six months is a bit arbitrary, but the data says the antibodies from an infection can last three months to five years. That's a pretty big dart board.
3) I, obviously, got the vaccine and haven't felt this good in a long time. More importantly, mRNA based vaccination research goes back 30+ years. Finally, I'd rather try and avoid long covid concerns. Ultimately I don't want my kid to get sick from covid, just like I don't want them to get sick from the flu. At the same time, we will hopefully reduce the spread of covid.
