McCormick: Measles are not like "Brady Bunch"

McCormick told NPR when she learned she was a Facebook meme a few months ago, she was angry.

"I was very worried about it and wanted to get to the bottom of it because I was never contacted," she said.

"

She's upset with a verbatim social media figurehead for the anti-Vax movement because she believes in vaccines.

"As a mother, my daughter was vaccinated," she said.

McCormick added that she got measles as a child and did not like the episode "The Brady Bunch," in which the older children sat by the sick cribs that play Monopoly.

"Having the measles was not a funny thing," she said. "I remember that it spread in my family."
