This is non randomized. The two biases are:
1. Behavior among those who got vaccinated likely different than those who don't
2. Likely those who didn't tested more aggressively
I would not cite this as many are doinghttps://t.co/rSkBC37uq0

The authors put it well: Even if affluent countries prioritize boosters for the vulnerable, 'the degree of additional benefit…is uncertain.' Yet we know 'vaccines could do a huge amount of good for the large number of vulnerable ppl who've not yet received a single dose.' https://t.co/6qNV6pzDDk
