Can't believe it, but I just found out I was awarded a fellowship at Harvard (the Foreign Language & Area Studies Fellowship -- not housed in the School of Public Health) that will provide me with full tuition award + a $15,000 stipend for the first year of the mph program. Still completely in shock as it is a university wide fellowship, and I really didn't think I had a chance competing against grad students from other Harvard programs.
The fellowship supports students who already have some proficiency in a typically under-studied language to continue to study that language alongside "area studies" courses (public health with a focus on SS Africa in my case).
It still leaves funding for the last semester of the program up in the air, but I think as of now makes Harvard my most affordable option.
