I believe the answer is:

antivenom

I'm a little stuck... Click here to teach me more about this clue!

'neutralising element' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'redeployed on vietnam' is the wordplay.
'redeployed' indicates an anagram (I've seen this in other clues).
'on'+'vietnam'='onvietnam'
'onvietnam' with letters rearranged gives 'ANTIVENOM'.

Can you help me to learn more?
