Can anyone give me some advice regarding the value of an MD/PhD vs. plain MD followed by a fellowship in Infectious disease? I am currently considering and MD/PhD in Epidemiology, which would prepare me to conduct epidemiological research. I've looked at a few post-MD fellowships in ID, and they combine both clinical training and research. At this point, I feel like I'll have to do an ID fellowship anyway for the clinical training, so would it still be worth doing the PhD? Also, the fellowship would have me doing research with other MDs whereas in grad school I would be mostly with PhDs so this may affect the focus of the training I get, and how useful it would be in the end. What is the difference in terms of competitiveness between MD/PhD and fellowships? I hope to be able to combine patient care and clinical research in ID, hopefully in international settings. Someone help, please!
