The Oxford coronavirus vaccine has released promising phase 2 data but how effective is it? How does it work? And what's the vaccine's storage temperature? Latest updates and news revealed.

The Oxford vaccine for coronavirus has started to release promising results just days after Pfizer and Moderna have shown the success rate of their RNA immunisations.

Currently releasing phase 2 findings of the Oxford vaccine trial, and working towards phase 3 results, the British public have many questions about their latest discoveries in a bid to help tackle the Covid pandemic including how does it work? And how effective is the Oxford Covid vaccine?

So what is the latest in the Oxford vaccine trial results? How does the Oxford Covid vaccine work? And what’s the storage temperature?

What are the latest Oxford vaccine results? Are there any side effects?

The latest update from the vaccine trial comes as phase 2 ends which has shown one of the groups most vulnerable to serious illness and death from Covid-19, could build immunity.

According to the researchers, volunteers in the trial demonstrated similar immune responses across all three age groups (18-55, 56-69, and 70 and over).

The study of 560 healthy adults - including 240 over the age of 70 - found the vaccine is better tolerated in older people compared with younger adults.

No serious adverse health events related to the vaccine were seen in the participants.

How effective is the Oxford Covid vaccine?

Overall, the Oxford coronavirus vaccine is proving to be 90% effect in all their cases.

In one trial, where participants had one course of dosing - that’s a half dose of AZD1222 (the vaccine name), followed by a full measure at least a month after - there was an efficacy rate of 90%.

In another, when two full doses were given at least a month apart, the Oxford vaccine was 62% effective.

How does the Oxford vaccine work?

Both Pfizer and BioNTech have used RNA technology where as Oxford have taken a different approach to their vaccine.

Scientists have instead taken genes from the spike protein on the surface of a coronavirus cell. They then make them into a harmless virus to make the vaccine to inject a patient with.

Once in the human body, it will start producing the coronavirus spike protein, prompting the immune system to produce antibodies and activate T-cells to destroy Covid-19. This ensures the body has a defence for the next time it comes into contact with coronavirus.

What’s the Oxford vaccine storage temperature?

At the moment, the scientists haven’t detailed the storage temperature for their vaccine.
