The science is clear on vaccines' safety and efficacy. But the presidential candidates' thoughts on vaccines? Well, they're a mixed bag.
Over the past week, Green Party candidate Jill Stein — who's a medical doctor by trade — entered the heated political debate over vaccines by suggesting there are still "real questions" about the medical devices that scientists say are generally effective and safe. She later added that she supports vaccines, but has questions about how they're regulated.
The small blow-up put attention on yet another bizarre element of the 2016 election: Out of the four big presidential candidates, only Hillary Clinton seems to be fully pro-vaccine, meaning she's the only one aligned with the scientific consensus on this issue. Republican Donald Trump is a straight-up anti-vaxxer, and the other two candidates — Stein and Libertarian Gary Johnson — have mixed records on the issue.
