"Everyone should ask questions, but I'm certainly not against them," she told "GMA" co-host Lara Spencer.
McCarthy, 41, addressed how she believes she's been wrongly branded by the public as being "anti-vaccine," and that misconception of her is a direct result of "people not doing their own critical thinking," she said today.
"I am not 'anti-vaccine,'" McCarthy wrote in an op-ed for the Chicago Sun-Times last month. "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.'"
She reiterated today how important reading her piece was for people to truly understand her stance.
"I think people should read exactly what I have said instead of reading headlines, and that's why I wanted to write that piece," McCarthy said. "Everything that I have said and everything that I believe in is in that piece, so I hope people will go and refer to that so they know exactly what I've been saying."
"I waited a year without dating, if you can believe it," McCarthy said. "I literally said, 'This is specifically what I want in a man,' and there he came."
Regarding her new hubby-to-be, the former New Kids on the Block boy band heartthrob, "I no doubt believe I got the cutest one," she said.
McCarthy's new book, "Stirring the Pot: My Recipe for Getting What You Want Out of Life," is in stores now.
