Facebook CEO Mark Zuckerberg is getting both support and backlash after posting a photo of his baby daughter as she was about to get her vaccinations.
The caption says: "Doctor's visit -- time for vaccines!" that prompted those who are against vaccines to post harsh comments, some calling him a bad parent, and that the vaccines are going to harm the baby.
Many anti-vaccine advocates claim there's a link between vaccines and autism, but that's now been widely-discredited.
