An important note from that article, lest the quote out of context feed any anti-vaccine fears: SIMON: Now, we should underscore, Jason, this is not the version of the vaccine that's given to youngsters in the United States. BEAUBIEN: Yeah. SIMON: Why are other countries still using it? BEAUBIEN: Right. So in the United States and in Europe and other countries like that, it - we're using an injectable vaccine, which is a dead vaccine. It is not a live virus, and it cannot cause polio. So that should not at all be a concern. The issue, however, is that it's an injection that has to be given. It's given four times between the ages of 2 months and 7 years. So just administering it is difficult. And just frankly, there is not enough global stockpile of that vaccine to vaccinate all of the children around the world, you know, four times over the course of their childhood.
