1B is very impressive but more than twice that in the same time really puts the capacity, scale and reach of the Chinese State at a different level. Still I am curious why China is not opening up the borders to visitors?
As far as I have read China heavily locks down regions if covid flares emerge, tests everyone in the region within a few days, then opens everything up less than a week later. This doesn't fit to the way more laissez-faire approach in the West.
"A large multi-country Phase 3 trial has shown that 2 doses, administered at an interval of 21 days, have an efficacy of 79% against symptomatic SARS-CoV-2 infection 14 or more days after the second dose. Vaccine efficacy against hospitalization was 79%."
