Amplifying efforts doesn't mean anything HHH. Its not an actual policy decision. He's just saying "Biden is trying harder!".

I didn't look too deeply into this, but from what I can tell the rate of vaccine has been basically linear with a stable rate of vaccination between the presidencies.
If you look at
this website you'll note that the daily dosage increase over time, so it doesn't really suggest anything about Trump handling things in any particular way since it is still a linear increase. Trump seems to have a smaller daily dosage but given the trend continues after his presidency it seems like that was mostly just because the infrastructure was still being rolled out.
So once again I'm going to ask you a simple question:
How is Biden's police different from Trump? You still haven't actually answered and I'm pretty sure you don't know what either president's policy is and won't admit that for some reason.
