op - just read through the rest of your thread. Good times.
A few thoughts:
I've been doing this for just over 3 years now.
My thread is here if interested.
There is a dengue vaccine. Just developed. Going through approval in various countries, so access is limited right now, but it's out there (for one of the serotypes, anyway) if you're interested.
If you don't already have a typhoid vaccine, you definitely want to get that. Also, Hepatitis A&B.
The yellow fever vac was a good idea. I carry my card around with me but have never needed to show it to anyone. You generally only need to show it if you've been a country with a yellow fever problem in the prior 6 days.
I'm in Kuala Lumpur, Malaysia right now. India is a few months out for me, and I'll be doing a counterclockwise circle like another poster did. Looking forward to reading your notes on it.
lol @ the haters. Live your life, don't worry about them.
