It's the same. Antibodies are not forever so the aim of the booster shots are to boost your antibody levels for Covid. I'm not going to guess at the reason why, but it would seem that the antibody duration for Covid is rather short.
This is in comparison to something like the tetanus booster you only need every decade.
