Curious... So the United Arab Emirates started vaccinating with the Pfizer vax on Dec 23rd¹. They're now at 2nd place w/ 16% vaxed. COVID-19 cases had been flat. But five days later they started skyrocketing _without_ a corresponding increase in testing.
Israel is also rising very fast, despite 25% getting their first dose. Though unlike UAE, cases started rising pre-vax.
Antibody dependent enhancement wasn't ruled out in the trials... hopefully not what's going on.
