One of the experimental coronavirus vaccines being developed and tested by Oxford University and AstraZeneca has shown an immune response against COVID-19 in trial volunteers, as per new data published in the Lancet.

The AZD1222 experimental vaccine uses an inactivated (harmless) form of the COVID-causing SARS-CoV-2 virus for the immune system to use as target practice to fight off a future coronavirus infection.

Based on the data released by the phase one/phase two study, which included 1,077 healthy volunteers, the vaccine was found to trigger two unique, important immune responses. The first response was an increase in the production of antibodies, which helps the immune system track and target the virus in the body. The second was an increase in a class of immune cells called T-cells, which destroy both viral particles and human cells infected by the virus, with the help of antibodies.

Scientists say this is a good sign for the experimental vaccine candidate, retaining its status as the front-runner in the global effort to find a working vaccine to prevent COVID-19 infection.
