UK coronavirus vaccine prompts immune response in early test

By MARIA CHENG AP Medical Writer

LONDON (AP) — Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot.

British researchers first began testing the vaccine in April in about 1,000 people, half of whom got the experimental vaccine.

Such early trials are designed to evaluate safety and see what kind of immune response was provoked, but can't tell if the vaccine truly protects.

In research published Monday, scientists said that they found their experimental COVID-19 vaccine produced a dual immune response in people who got the shot.
