I took the Moderna shots.

T-cell immunity does not decline at all in years, or even decades.
If one has resistance that fades, it can not be from T-cell immunity memory.

While antibodies normally only live a few months, there are several possibilities.
One is that the mRNA vaccine may linger longer than believed, constantly re-stimulating antibody production?
Or the spike proteins could have a backlog stored inside cells, that slowly escape and stimulate antibody production?
Another possibility is that the spike protein generation somehow stimulates longer lasting antibodies?
It is also possible that their testing simply was not accurate enough. I have no idea how they tested for efficacy since that would require deliberate exposure and accurate testing.

But normal vaccine efficacy does not and can not decline.
That is not possible in months or a year even.

"T-cell immunity does not decline at all in years, or even decades."
Link? Immune system memory declines over time for all vaccines. In fact, even live vaccines decrease over the years.

"mRNA vaccine may linger longer than believed, constantly re-stimulating antibody production"

mRNA vaccines are instructions on creating the spike protein and getting it to the outer layer of the cell so that it can illicit an immune response which leads to immune system memory. They are both gone both gone from the body within 2 weeks. Even if they remained longer they would not create an immune response and memory. In fact the spike protein created by the mRNA deteriorates slowly and in about two weeks it would not create antibodies 5 or 6 months after vaccination.

"Or the spike proteins could have a backlog stored inside cells, that slowly escape and stimulate antibody production?"
And elephants could fly. How about a link that spike proteins backlogs stored in inside cells and please no more irrelevant bullshit.

"But normal vaccine efficacy does not and can not decline."
No vaccine is 100% effective against any disease and all vaccines efficacy decreases with time. Efficacy of the non-attenuated live vaccines decrease slower. Other vaccines such as the flu vaccine, mrna vaccines lose efficacy faster thus the need for booster. The trade off is safer vaccines that do not use live virus for high efficacy vaccines that need boosters.

Moderna and Pfizer are one of the most poisonous.

They all are venomous ....but those two...wow

Mercy on those who took this jab.

Heart inflammation risk in Pfizer and Moderna jabs evaluated

The European Medicines Agency's safety committee has confirmed a “very rare” risk of myocarditis and pericarditis in individuals who've had the Pfizer-BioNTech or Moderna Covid vaccines, having conducted large Europe-wide studies.

Nor does the number of deaths due myocarditis and pericarditis caused by the Pfizer or Moderna vaccines which are now 0 out of more than 400 million does given in the US.
