In fact I need to go Kathmandu again next week to get my Japanese B Encephalitis jab at the CIWEC clinic :

CIWEC is recommended as absolutely the best place in the Kathmandu area for health care and travel health advice. The travel nurse I saw for jabs in the UK checked it out online for information. BTW this was at the excellent Nomad Travel and they are also very good for those of you in North or even Central London:

Wherever in the world you are coming here from, I would definitely recommend you check out the CIWEC clinic site and do so in good time before you leave. All the information they give is up to date, easy to read and clearly thought out. So, there you go, safely.

Namaste :) .
