Oxford Covid-19 vaccine produces immune response across all ages - AstraZeneca

"It is encouraging to see immunogenicity responses were similar between older and younger adults, the spokesman added". It's unclear when AstraZeneca will publish the results of its large ongoing trial that will help determine its vaccine's safety, but it is expected to be one of the first vaccine candidates to seek regulatory approval, Reuters reports.

However, Health Secretary Matt Hancock said vaccinating health workers was not his "central expectation" though he did not rule it out.

Researchers looked whether the vaccine accurately follows the genetic instructions programmed into it by the Oxford team, providing clarity on how it provokes an immune response. The hope is that the human body will then attack the novel coronavirus if it sees it.

"We do not know the efficacy at this point and that is why we are eagerly awaiting the phase-three trial results", she told Al Jazeera from Lucerne, Switzerland.

Blood tests carried out on a set of older participants reflect data released in July which showed the vaccine did generate "robust immune responses" in healthy adults aged 18 to 55. It did not name the publication.

Several dozen vaccine candidates are now being tested in clinical trials, ten of which are in the most advanced Phase 3 stage involving tens of thousands of volunteers.

"Moderna has been working since the early days of the pandemic on the development and testing of a Covid-19 vaccine".

The Hyderabad-based vaccine maker had applied to the Drugs Controller General of India (DCGI) on October 2, seeking permission to conduct Phase 3 trials.

Wilder-Smith said there is a possibility that several vaccines could be rolled out simultaneously.

Professor Adrian Hill, the founder, and director of the University of Oxford's Jenner Institute said that emergency approval would allow people most in need to receive the vaccine shot, while the final trials are underway.

"We continue to work with several leading pharmaceutical companies around the world who are in the process of developing potential vaccines for Covid-19".
