I did some searching and didn't find any diaries on this (happened April 12th this year). Jenny Mccarthy is walking back her anti-vax stance in an open letter to the Chicago Sun-Times. For sure this is some CYA weasel-words and I am hoping this is a sign that she is feeling some pressure from public opinion.
I am not “anti-vaccine.” This is not a change in my stance nor is it a new position that I have recently adopted. For years, I have repeatedly stated that I am, in fact, “pro-vaccine” and for years I have been wrongly branded as “anti-vaccine.”
