Oxford Coronavirus Vaccine

Oxford’s scientists explain the Phase I/II results for the COVID-19 vaccine and the immune response it creates in humans.

A team of scientists at Oxford University’s Jenner Institute and Oxford Vaccine Group has 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 today in the scientific journal, The Lancet, indicate no early safety concerns and induces strong immune responses in both parts of the immune system.

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).

The Phase I/II data for our coronavirus vaccine shows that the vaccine did not lead to any unexpected reactions and had a similar safety profile to previous vaccines of this type. The immune responses observed following vaccination are in line with what previous animal studies have shown are associated with protection against the SARS-CoV-2 virus, although we must continue with our rigorous clinical trial programme to confirm this in humans
