Much ado as vaccination begins

Wednesday December 9th 2020

The Oxford university COVID-19 vaccine still lacks data on its effectiveness on adults over the age of 55, according to the first peer-reviewed analysis of the new vaccines.

The Lancet published the findings last night hours after the UK began the first routine vaccination programme against COVID-19 using the Pfizer mRNA vaccine.

The first vaccination was delivered in Coventry by a nurse May Parsons to Margaret Keenan, aged 90, and the second went to William Shakespeare.

Reports from individual hospitals suggested a number of ICU staff were included in yesterday’s vaccination programme. One of the first was senior sister Ly Fletcher in Walsall.

The Lancet report on the Oxford/Astrazeneca adenoviral vaccine involved 11,000 volunteers in the UK and Brazil. Just 12% were over the age of 55 and only five of these contracted the virus – making it impossible to reach conclusions about efficacy in this group.

Including volunteers from South Africa, researchers were able to report safety data from 23,000 participants with just three serious adverse incidents, one of them involving a recipient of placebo. The researchers say a case of severe fever in the vaccinated group but say it seemed to be an “expected vaccine-related event.”

The report confirms overall efficacy of 70.4% with 90% achieved in a UK-based trial group, representing nearly a third of the total participants and receiving and receiving a half dose in their first injection.

Professor Sarah Gilbert, from Oxford University, said: “We have known for many years that adenoviral vectored vaccines fulfil the requirements for use against outbreak or pandemic diseases. They are safe, highly immunogenic, can be manufactured in large quantities at low cost and do not require frozen storage.

“Following the demonstration of vaccine efficacy in many preclinical studies, we now have clear evidence of efficacy in the trial results presented in a peer-reviewed publication today. Now under regulatory review, we hope that this vaccine will shortly be in use to start saving lives.”

Dr Charlie Weller, head of vaccines at Wellcome, said it was “critically important” that the trial was completed.

Dr Weller said: “Although we await the trial completion and full data, it is highly encouraging to see the data behind the interim results announced last month, including an analysis of the different dosing regimens. This suggests that this vaccine could prevent asymptomatic disease.

“It’s important to remind ourselves that there are still important questions to be answered on the efficacy of this vaccine across different age groups and in different settings, which we will only be able to fully understand once Phase III is completed.

“The reassurance this published data provides is particularly welcome as the University of Oxford/AstraZeneca vaccine can be easily administered in existing healthcare systems around the world. It can be stored at fridge temperature and can use existing delivery mechanisms, giving it a distinct advantage for swift and successful global rollout.”
