The situation changes when you’re dealing with the evolution of a new variant such as the Delta variant. And what we are seeing right now, that there are reinfections. The protection you get from the original infection still exists somewhat, but reinfections occur at a much greater rate among individuals now than we did against the original alpha. So, bottom line is, when you’re dealing with a variant, you don’t get the kind of protection that you would have hoped to have gotten from a previous infection.

Regarding the issue of vaccinating people, there’s no doubt when you vaccinate someone who has had an original infection and who has recovered, not only do you increase the depth of the–of the protection, not only do you increase the duration, but you also increase the breadth of it so that you cover not only the original but the variants. And that’s the reason why the recommendation still holds that even though you’ve seen infected previously in the context of variants, it’s a good idea to get vaccinated anyway.
