The frightening and false information that is being propagated by anti-vaxxers has led many people to either not vaccinate their children or decide on changing the rate at which the dosages are given, which is also dangerous. These people claim that they are not anti-vaccine but are merely seeking safer vaccines or methods of delivery. But their actions are harming the population at large.
John Oliver presents the case for why these people are wrong and ends by describing how he vaccinates his own prematurely born son on schedule, even despite the fears that the anti-vaxxers have infected his brain with. And that is often the case. People cannot shake off fears like this easily. People feel more guilty of bad results that might occur because of the things they do more than they feel guilty because of bad results because of things they did not do. So they tend to favor inaction.
