Uninformed is commonly followed by about or of when talking about missing knowledge or information. Other prepositions usually belong to the wider sentence.
Use uninformed about or uninformed on for topics and issues. Use uninformed of for facts, decisions, or events, especially in formal English. By and in usually have different grammatical roles.
These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.
About is common in everyday English for general topics.
Of is slightly more formal and often implies missing information intentionally or officially.
On is common in journalism, politics, and discussion of issues.
In can appear when referring to lack of knowledge within a field, though it is less common than about or on.
The same subject can take different constructions because each sentence answers a different question.
