How do I go from MBBS/postgrad to working as a doctor for the UN, WHO, or UNICEF?

r/

Hi everyone! I’m currently in the process of pursuing my undergraduate medical degree (MBBS), and my dream is to work as a doctor for global organizations like the UN, WHO, or UNICEF — ideally in the field, contributing to humanitarian missions and global health initiatives.

I’m planning to complete postgraduation (possibly via USMLE), and I’m trying to understand:

●What kinds of postgraduate specializations are most helpful for these roles?

●Do I need a Master’s in Public Health (MPH) or something similar?

●How important is field experience, and where can I get it?

●What are entry-level jobs or internships I should apply for after PG to start this journey?

●Any UN talent pools or rosters I should register for early on?

If anyone here has taken this path — I’d love to hear your story!
Any insight or links would mean the world. Thank you!
