Explanation:

- The sentence is: "Scientists (1) ______ Oxford University say their experimental coronavirus vaccine (2) ______ been shown in an early trial to prompt a protective immune response..."

- Let's check the options:

1. was – "was been shown" is grammatically incorrect.

2. had – "had been shown" would work in past perfect tense, but the context here is reporting current findings.

3. have – "have been shown" is used with plural subjects, but "vaccine" is singular.

4. has – "has been shown" (present perfect passive) is correct for a singular subject ("their experimental coronavirus vaccine").

- So, the proper choice is option 4: has.
