(42,326 posts)Pulitizer Prize winning journalist Laurie Garrison explained that this morning on his show. If anyone has access to Jonathan's show on their on-demand or dvr, I highly recommend watching it. In fact, I'll probably watch it again. It has to do with the window of time the antibodies have to muster a defense after they have been in the body for a while. It's kind of like your memory--sometimes you can't quite think of what you need, but given a little time it comes back.
With the Delta variant being so much more efficient, there is going to be an effect. In other words, the antibodies are there but not quite ready to do their job. They do, however, regain their memory and protect the person.
If anyone watches this segment and wants to add to this post (or even correct anything I've gotten wrong), please do so.
Laurie Garrison is my absolute fave when it comes to explaining this virus. She is very, very smart.
