Closer to 6 months I think? But yeah. Not sure why you think China hasn't been an infection experiment. We've been rats in a cage for the last 3-4 years, and even less immunity due to lack of exposure until recently.
I never got the vaccine but I fared better than my friends who got double/triple boosted, but I mean, that makes sense. If we're comparing it to a regular flu then we are constantly updating the flu jab every single year because of its rapid mutation rate. Don't see why this one would be any different.
To be sure, this version feels very different to last time. This one is significantly weaker and more common symptoms; barely different to the colds I get as a result of working in a school, but weirdly makes me even more miserable because I still have to go to work.
That being said, I'm not really concerned about any such long term HIV mega effects unforeseen or whatever. Every illness and glass of wine we have permanently changes our outcomes, immunities, and longevity.
If it looks like a shit, smells like a shit, feels like a shit and tastes like a shit, it's probably not a government conspiracy to permanently alter our DNA into obedient slaves. More likely, it's a shit. Or Joe Biden. Same outcome either way
