Apparently, around half of new parents in the UK are targeted with misinformation about vaccinations by the anti-vaxxers (https://www.theguardian.com/society/2019/jan/24/anti-vaxxers-spread-misinformation-on-social-media-report). I'm sure that the inventors of the world wide web didn't expect it to be used for this purpose. Many parents reportedly believe that you can have too many vaccinations (it depends what you are likely to be exposed to).
