could you pl change the sentence in indirect speech : He said,'why don't you get vaccinated ?

He asked why I didn't get vaccinated.

Ms Sue thank you for your quick response but i was told that do and did forms would not appear in reported speech could you clarify and how about this one : he enquired why i was not vaccinated

Yes, that's good, also.

He suggested that he(patient) get vaccinated.

To change the sentence into indirect speech, we need to report what someone said without using their exact words. Here's the modified sentence:

He asked why I didn't get vaccinated.
