Answer:
- Injected, inoculate.
Step-by-step explanation:
Denotation is associated with the literal or dictionary meaning of the word. It defines the word literally which is contradictory to the connotative or suggested meaning of the word.
In the given passage, the word 'immunized' denotes 'to make someone immune to something through vaccine or inoculation.' The other words proffering similar denotation would be 'injected or inoculation' as it technically conveys the alike definition i.e. 'to introduce to a material or vaccine in order to generate immunity.' Another word conveying similar essence can be 'vaccinate.'
