Oxford COVID-19 vaccine variant study opens in NHS Lothian

Oxford COVID-19 vaccine variant study opens in NHS Lothian

1st July 2021

The University of Oxford in partnership with AstraZeneca are leading the Phase II/III study, supported by NHS Research Scotland and recruiting in Edinburgh’s Western General Hospital, which will assess the safety and immunogenicity of the vaccine aimed at preventing the Beta COVID-19 variant, in both previously vaccinated and unvaccinated adults

The study will recruit approximately 1,865 participants across the UK, South Africa, Brazil and Poland, including 800 participants across the 14 UK sites.

The new variant vaccine, known as AZD2816 has been designed using the same adenoviral vector platform developed by researchers at the University of Oxford using the ChAdOx platform technology, with ten minor genetic alterations to the spike protein based on the Beta (B.1.351, South African) variant.

The variant vaccine will be administered to those previously fully vaccinated with two doses of original Oxford/AstraZeneca or an mRNA vaccine (Pfizer and Moderna), at least three months after their last injection. AZD2816 will be given as two doses, in non-vaccinated individuals four or twelve weeks apart, or given as a second dose following a first dose of Vaxzevria four weeks apart.

Professor Sir Andrew J Pollard, Chief Investigator and Director of the Oxford Vaccine Group at the University of Oxford, said: “Testing booster doses of existing vaccines and new variant vaccines is important to ensure we are best prepared to stay ahead of the pandemic coronavirus, should their use be needed.”

Dr Maheshi Ramasamy, Principal Investigator at the Oxford Vaccine Group, said: “The UK vaccine roll out programme has been incredibly successful at preventing hospitalisations and deaths, but we don’t know how long protection lasts. This study will provide vital evidence on whether further doses including ‘tweaks’ against new virus variants may be needed in the future.”

The study is recruiting participants until August, with initial data from the trial expected later this year. Once available, data will be submitted to regulators for assessment as a next-generation booster vaccine and through an expedited regulatory pathway.

Study volunteers will be recruited across 14 sites in the trial, including:

  • University of Nottingham Health Service (Cripps Health Centre)
  • North Manchester General Hospital
  • Freeman Hospital
  • University College Hospital
  • Royal London
  • Western General Hospital
  • Thomas' Hospital
  • King's College Hospital (Denmark Hill)
  • Derriford Hospital
  • Churchill Hospital
  • Bristol CRF
  • Southmead Hospital
  • Northern General Hospital
  • Hull Royal Infirmary
