> gained additional protection against the Delta variant.

we've officially come full circle!

my original complaint is that these studies all baseline against candidates that were vaccinated within the 6 months prior to publishing.

the gained improvement is already marginal in this scenario, but if the improvement diminishes even further, then it's hard to justify a mandate.

I don't understand. Yes, many of the vaccine effectiveness studies are limited by the window of time they use. That's a separate issue from vaccines being redundant for previously infected people. Studies show that previously infected people still benefit from vaccination.

yes, the studies show it's better .. in a 6 month time frame.

after that, who knows?
