"Everyone should ask questions, but I'm certainly not against them," the View co-host said during an appearance on GMA this morning.
McCarthy most recently penned an op-ed for the Chicago Sun Times in which she insisted she was "wrongly branded as 'anti-vaccine'" after she spoke out about what she believes is a link between autism and vaccinations given to children (her son Evan was diagnosed with the behavioral disorder in 2005).
"This is not a change in my stance nor is it a new position I have recently adopted," she wrote. "I've never told anyone to not vaccinate."
"My beautiful son, Evan, inspired this mother to question the 'one size fits all' philosophy of the recommended vaccine schedule," she continued. "I embarked on this quest not only for myself and my family, but for countless parents who shared my desire for knowledge that could lead to options and alternate schedules, but never to eliminate the vaccines."
McCarthy told Lara Spencer that it is important for people to read her piece in its entirety in order to truly understand her stance, noting how many are too quick to judge.
"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.
McCarthy has often found herself on the receiving end of criticism due to her controversial stance on vaccinations. In a 2008 interview with Larry King, the former Playboy model asked, "Isn't it ironic, in 1983 there were 10 shots and now there's 36 and the rise of autism happened at the same time?" She continued, "We need to get rid of the toxins, the mercury—which I am so tired of everyone saying it's been removed. It has not been removed from the shots."
In March, she was crucified on Twitter after asking her fans what the most important personality trait you look for in a mate is and just one month later, she penned her op-ed to clarify her viewpoint.
But that's not the only headline McCarthy's been making as of late. The blond beauty is also newly engaged to Donnie Wahlberg and clearly could not be more thrilled to wed the 44-year-old former boybander.
"I waited a year without dating, if you can believe it," McCarthy said on GMA. "I literally said, 'This is specifically what I want in a man,' and there he came."
As for her New Kids On The Block hubby-to-be, Jenny gushed, "I no doubt believe I got the cutest one."
