Nicholas Kristof remains a pro-vaccine type of guy, and he intends on persuading his audience to turn pro-vaccine as well by sharing information on how vaccinations have improved public health . In the beginning of his article, the author shares examples about leaders in our government who have not vaccinated their children and then seemed to abandon their ways of thinking. For example, he wrote, "Senator Rand Paul told CNBC that he had delayed his own children's immunizations and cited "many tragic cases of walking, talking, normal children who wound up with profound mental disorders after vaccines." He seconds this example with a remark from President Obama who seemed to suggest the science is inconclusive about a link between vaccines and autism. In the middle of the author's argument, the author moves on to blatantly state that vaccines have revolutionized public health. Kristof also continues to support with his argument with an appeal to credibility by claiming, "In reporting poverty worldwide, I've seen how much vaccines improve human well-being." At the end of Kristof's argument, he ends with an appeal to pathos by saying, " The point of immunization isn't just to protect your own child, but to also protect others. Thus refusing to vaccinate your children is not "personal choice" but public irresponsibility." His argument is overall, a solid one. However, there is one weak place that contradicts his argument when he appeals to logos. He writes, "According to the WHO, the measles vaccination rate in 2013 stood at 91 percent in the United States-lower than Zimbabwe or Bangladesh." If 91 percent of Americans vaccinate their kids, then the issue on anti-vaccination isn't that bad as the author makes it to be in his article. The conclusion of his argument ended with a quote that summarized his opinion and provided evidence to support it.
