Questions & Answers about Aşının geliştirmekte olduğu bağışıklığı ölçüyoruz.
How does the structure geliştirmekte olduğu translate to "that the vaccine is developing"?
This is the formal present continuous object relative clause taught in this lesson. It combines the verb geliştir- (to develop) with the formal continuous suffix -mekte, followed by olduğu (the -dık relative participle of olmak + the 3rd-person possessive -u). It creates an ongoing, active description: "the being-in-the-process-of-developing".
Why is the subject Aşının in the genitive case instead of just Aşı?
In Turkish object relative clauses (where the noun being described is the object of the action, not the subject), the doer of the action must take the genitive case. Because "the vaccine" is doing the developing, it becomes Aşının, which pairs with the possessive ending on olduğu.
What exactly is happening with the spelling of bağışıklığı?
The root noun is bağışıklık (immunity). The final -ı is the accusative case suffix, marking the entire phrase as the specific direct object of the main verb ölçüyoruz (we are measuring the immunity). Adding this vowel causes the final -k to undergo consonant mutation, softening to -ğ.
Could we just say Aşının geliştirdiği bağışıklığı? What does -mekte olduğu add?
Yes, you can! However, geliştirdiği can mean both "that it develops" (general) or "that it developed" (past). By using geliştirmekte olduğu, you specifically emphasize that this is an ongoing process happening right now. The -mekte suffix also gives the sentence a formal, scientific tone.
