Oxford coronavirus vaccine produces strong immune response – New Study

A team of scientists at Oxford University’s Jenner Institute and Oxford Vaccine Group have taken the next step towards the discovery of a safe, effective and accessible vaccine against coronavirus.

The results of the Phase I/II trial published on Monday in the scientific journal, The Lancet, indicate no early safety concerns and induces strong immune responses in both parts of the immune system.
According to the University of Oxford, the vaccine provoked a T cell response within 14 days of vaccination (white blood cells that can attack cells infected with the SARS-CoV-2 virus), and an antibody response within 28 days (antibodies are able to neutralise the virus so that it cannot infect cells when initially contracted).
During the study participants who received the vaccine had detectable neutralising antibodies, which have been suggested by researchers as important for protection, and these responses were strongest after a booster dose, with 100% of participants’ blood having neutralising activity against the coronavirus. The next step in studying the vaccine is to confirm that it can effectively protect against SARS-CoV-2 infection.
