Variants probably important. But even the original will get inhaled to find weakened immunity after time passes.
Of course, after time passes the latest variant will have replaced the original.
I encountered a guy just this evening with his 2nd infection. First was May 2020. Now another. He says the reason he got tested was he was sick for a week and on the verge of going to the ER, but never went. Feels like he’s improving.
Age I think 58. Got a little lucky.
I’m 53 and I eat covid for breakfast.
Seriously, it’s everywhere.
On my eggs, my milk, my cereal, my toast.
