So I am still curious about what is going to happen to countries who have employed so far the "zero-covid" strategy once they finally open up.<p>Granted, I assume most of their population will be vaccinated, but there seems to be growing evidence that natural immunity gives you at least equal, or in some cases better protection than an mRNA jab(specially against new variants).<p>It also seems to be an established fact that older folks, who happen to be the most vulnerable group, do not respond as well to vaccines as one would've hoped.<p>I suspect that countries like Australia, NZ and China will still have to endure reasonably big COVID waves - surely they will be attenuated by the high vax rate, but will still be deadly enough to stress their healthcare system.<p>I do believe that they had the winning strategy against covid, but there are still unkwnown unknowns.
