'something injected' is the definition.
I can't tell whether this defines the answer.

'ruins meat badly' is the wordplay.
'badly' is an anagram indicator.
'ruins'+'meat'='ruinsmeat'
'ruinsmeat' is an anagram of 'ANTISERUM'.

Can you help me to learn more?

(Other definitions for antiserum that I've seen before include "Medicinal fluid" , "Injection; I'm at nurse (anag.)" , "shot" , "bloody stuff" , "treatment against disease" .)
