Currently they're being offered Moderna/Pfizer, but there's not much of either of those around. Pfizer in particular is being used mostly for second doses, and that will continue through May. My 21 year old niece has been offered the jab (as a carer for her mum) but hasn't been offered an actual timeslot - the website booking system is showing AZ only as a first dose option in this area. She did actually book an AZ appointment, but was told (when she arrived at the site) to go home again, and just keep trying the booking system.In the UK, when are under 30s going to be offered the vaccine and which brand will be offered? Is any of this known yet?
The numbers still say that everyone can have a first jab by the end of July. That's without adding in any new suppliers.
Novavax may finally start contributing in June/July, maybe others (like Curevac or J&J) as well - but until they're approved and the stock is in place no one knows if they'll actually help bring that end July date forward.
There's also the possibility that AZ and J&J may get phased out of the plan which could change the timeline in the other direction.
