All of them are old except from the one from 2016, which is a joke, you know, he is a comedian. He had a vaccine expert on not that long ago who basically confirmed that vaccines causing autism is bs. You can criticize rogan all you want, but he tries to learn, and invites experts on all the time who end up changing his mind quite often. Also, he never was against vaccines. He was just pointing out that vaccines do cause serious issues occasionally, which is a fact. I guess you could argue that it's irresponsible, and could potentially make people not vaccinate their kids, but it is the truth. Like when you get the surgery, don't you want to know the risks?
