During my second year of graduate school, I moved in with my sister’s family to save money. “You must get the flu shot if you are going to live here,” my sister declared. Both of my nieces were under the age of 5, putting them at a high risk of flu complications; therefore, it was critical that I do my part in, first, getting vaccinated to minimize my risk of getting the flu, and second, not passing the flu to a vulnerable population. A key part of this was, and still is, washing my hands regularly.
