Vaccine trial participant and CNN correspondent's big reveal. Was it the placebo or the real thing?

Months after CNN correspondent Stephanie Elam started the vaccine trial, she finds out if she really got the J&J shot.

But this appointment is going to be different. Since my last check-up, Johnson & Johnson has been granted emergency use authorization for its single-shot Covid vaccine. As a thank you for those of us who participated in the randomized, phase three vaccine trial, the company is unblinding participants and administering the vaccine to the placebo group. I am looking forward to this unblinding with the same exuberance I had as a kid the week of Christmas. All of those presents under the tree just waiting to be opened! But this time, my present is protection against a deadly virus -- an inoculation that is literally saving lives.
