It has come out in the last two weeks that the mRNA shots are sometimes destroying previous acquired and natural immunities. A close acquaintance got the jab and later got shingles. They were surprised because they thought they had a lifetime immunity to the Herpes Zoster virus.
The first disease mentioned in the report on decreased immunities was shingles! Obviously you don't have shingles, but this report in general might apply to your experience.
That’s why I’m refusing to be vaxxed. Way too many side effects that we know about. No telling what will happen that we don’t know about yet.
