inoculate

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

'protect from disease' is the definition.
I can't judge whether this definition defines the answer.

'i clean out wound' is the wordplay.
'wound' indicates anagramming the letters (wound can mean twisted or turned around).
'clean'+'out'='cleanout'
'cleanout' with letters rearranged gives 'noculate'.
'i'+'noculate'='INOCULATE'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for inoculate that I've seen before include "Induce immunity" , "Immunise, vaccinate" , "Inject against a disease" , "to prevent infection" , "Give a jab" .)

I've seen this clue in The Irish Times.
