I’ve been saying for months that our blood tests show my wife who was infected in Oct 2020 and Moderna jabbed in Dec ‘20 and Fed ‘21 has 1/2 the antibody count that I have. I had fauciflu in Oct 2020 and NO JABS. My AB count has been off the scale @ >2500 since first tested in June 2021, our August tests shows hers is at 1400. We get tested again in early Nov ‘21.
Please post again and tell us if her overall immunity continues to decline.
Good luck.
1400 sounds more than adequate for protection. You wife’s immune system may be different than you or it could be the moderna shot reducing her levels...who knows.
