I don’t think the media is in any way part of the anti-vax movement. The incidents are being reported because they have to. The media is not saying it is due to the vaccine.
They've always been reported but in the past they remained mostly minor stories of local interest.
Now anti-vaxers scour the web to find these articles, post them everywhere on social media and on forums like FR, and make people think the incidence has increased.
I don't think it has, which is why I keep asking for data.
