"When my mom was seven years old, her brother died of polio. He was a healthy kid at the time, and the polio vaccine was developed just a few months later. Although over half a century has passed, we still face many challenges to vaccinating children against vaccine preventable diseases. My goal is to partner with parents, providers, public health officials and others to better understand these challenges and to improve timely receipt of needed vaccines in order to prevent serious complications and even death from diseases like polio."
