I know one person who says she has long covid, she was vaxed up with the astra zenica vax and lives in Cyprus, she keeps getting covid over and over. I know quite a few who are purebloods and none of them have long covid.
She is probably among the few but statistically notable number of folks whose immune system is highly compromised by the vax and boosters. I haven’t seen any info on if these folk ever get their immune system back in order. The RNA modification may not be reversible.
