This is what the third booster does and probably also what being vaccinated closer to infection date does. This is exactly what happens when you have more antibodies.
The contradiction is that two media outlets are stating opposite statements from the same source with regards to whether the 4th booster raises the amount of antibodies.
Are you referring to the Omicron variant? Current theories suggest that Omicron evolved inside a HIV patient. There is no reason to believe the patient was vaccinated.
Omicron evades the body’s antibodies generated from infection by the delta or alpha or wild type variants, so there’s no plausible case for vaccine “selective pressure” especially as it emerged from a region of the world with very low vaccination rates.
Fourth vaccine dose boosts antibodies, researchers say, but likely not enough to prevent Omicron breakthrough infections http://lite.cnn.com/en/article/h_69134b5be555abcb7c1609154ab...

”Maybe there are a few more antibodies but not much more compared to the third dose,” said Regev-Yochay. -----

And what we see is that the Pfizer vaccine, after two weeks, you see an enhancement or increase in the number of antibodies and neutralizing antibodies -- a pretty nice increase. It's even a little bit higher than what we had after the third dose," Regev-Yochay said. -----
