I think it is more less developed countries taking longer to approve vaccines and obviously struggle with distribution, so the Pfizer vaccine hasn't been an option. India has just approved the Oxford/AZ vaccine and have 50m doses sat waiting, so expect to see their bubble swell in the coming weeks.
Israel is interesting as they are leading in terms of % of population vaccinated as they chose to pay a premium to get things early as calculated the extra cost would still be a net gain economically if they can unlock sooner.
Also found this really interesting - it looks like the one thing we are getting right is getting the vaccine out although am a bit worried about vaccine nationalism globally (ie getting to the richest countries rather than simply those in the most need)
