Covid: Oxford vaccine shows ‘encouraging’ immune response in older adults

Bearing in mind the skewed demography of rural England this is very good news. The story tells us:

The Oxford coronavirus vaccine shows a strong immune response in adults in their 60s and 70s, raising hopes that it can protect age groups most at risk from the virus.

Researchers say the Lancet phase two findings, based on 560 healthy adult volunteers, are "encouraging".

They are also testing whether the vaccine stops people developing Covid-19 in larger, phase three trials.

Early results from this crucial stage are expected in the coming weeks.

Three vaccines - Pfizer-BioNTech, Sputnik and Moderna - have already reported good preliminary data from phase three trials, with one suggesting 94% of over-65s could be protected from Covid-19.

The Oxford data is from an earlier stage, which tests the safety of the vaccine and the body's response to it, but in the long run it's likely this vaccine could be easier to roll out because it doesn't need to be stored at very cold temperatures.

The UK government has ordered more of the Oxford vaccine, manufactured by AstraZeneca, than any other - 100 million doses - compared to 40 million doses of the Pfizer-BioNTech vaccine and five million of the Moderna vaccine.
