I had my booster last week.. being in the country was just a matter of walking into the pharmacy and getting the jab and then hanging around for 15 minutes..
the city must be bedlam!
Being near City center, it was the same for me. Walk up, jab, sit for 15, walk away. About 500m from the house. It's the bookings that are full. But all the chemists just had a drop of Moderna a few days ago. When I asked about bookings right before the drop, my chemist said "bookings are full, but we expect the drop tomorrow, you can just come over, then." Moderna was what I wanted, anyway. Pfizer was my main 2 dose vax. I had read (anecdotally) that mixed vax & booster might give broader protection. I have no evidence but I figure, why not? Plus, from an engineering perspective, I like the Moderna better. Easier transport, shipping, stability. Moderately more effective. I think AU is ramping up to produce it (finally). We need to get it to the Islands around us.
Of course, 2 days before Christmas, everyone was rushing. Only a week before, AU dropped the time to booster from 6 months to 5. It will be 4 in 10 days. The big mess is airports. As Omicron pops, flight crews are being grounded. Add to that, PCR test and result times have gone from hours to over 3 days (and you need under 3 days to fly), and people are screwed.
The upside is that everything I've seen shows omicron *way* less dangerous. Almost a non-issue for vaxed. Of course, you can still spread it. For less time. But during the max load window, just as contagious. Or so I've read. I've put some time into it. Then I defer to the doctors I know
If someone doesn't show up (in Sydney), there's a waiting list anyway. They just call the next person on the list. This is Pharmacy & GP jabs. I would think in the large vax places, they just open another booking, when someone doesn't show. It's not like they bin the unused vax. Sure, they block a booking slot. If done intentionally, well, that person is an ass. They almost certainly were before, they will probably be right up to the end. Not much we can do about it
