We know modern induced antibodies last longer than Pfizer ones. This is most likely dose response function. The pfizer trio will put folks at 90mcg the three modernas will be 250mcg. The pfizer triple is less than 1 moderna. Side effects may increase though at the higher dose though.

But antibodies aren't the only thing that matters; focusing only on antibody levels without acknowledging that you only care about antibody levels _as a proxy for protection_ is the error I talked about in my comment.

There are Memory T cells and Memory B cells that last for decades. So if these cells were able to fend off the virus by themselves, you could have zero antibodies and be fine.

Some possibly useful articles:

* https://en.wikipedia.org/wiki/Memory_B_cell

Yes they are a measurable proxy. But if you read the article and look at break thru infections and hospitalizations you see that t-cell immunity is either waning or not relevant.
