I am with the OP. Vaccine administered on 10th with no hassles at all. Pretty orderly except for a small number of expats who would struggle with a paper bag (and then blame the locals).
I am an existing BHP patient, so have a BHP number - you need that to register, but the online form is simple to complete and I had an email reply with confirmation of date and time in minutes. I never received an SMS and understand anecdotally that one is only sent if your appointment date/time is changed. Showed confirmation (on my phone) to reception staff, was given additional form. That and passport were all that were required.
Second jab 2 Nov all being well.
Congrats to BHP for a well organised and coordinated job.
Altjough currentyl not open for new registrations, those who are waiting may wish to bookmark and try each day:
