That's the pro-vaxx idiots suffering from the Gell-Man Amnesia effect, since the media is lying from top to bottom about everything: Trump-Russia collusion, climate change, no evidence of voter fraud, peaceful protests, #Gamergate....

Yes, this would apply to anyone who believes anything that the media has to say. If it said that the sky is blue, I'd check just to make sure.

What kind of fool recognizes that the media has lied about everything else, but suddenly they're right about the vaccines being safe?

The media is right about any number of things. Hell, in order to lie, you need to be able to get some things right. The issue is not believing that the vaccines are safe, as stupid as it is to believe that they are either 'safe' or 'unsafe', but that they are either safe or unsafe because what has been said in the lying media that you happen to have consumed.
