This type includes AstraZeneca, and uses a modified adenovirus to deliver DNA coded with a SARS‑CoV‑2 protein to spark the body's immune system into action. Three main types of vaccines have so far been used in the fight against Covid-19 around the world, but more are in trials and under development. Now researchers are exploring whether the use of AstraZeneca may have played an important role in the UK's resistance to the latest wave. Pfizer and other mRNA jabs package the vaccine in a droplet of fat, while the AstraZeneca delivers its vaccine via the shell of another harmless virus, the adenovirus. Most other countries relied on mRNA jabs like the US-produced Pfizer, while China and Russia produced their own. The UK and Australia were the two main nations to have a widespread rollout of the locally produced and Oxford University-created AstraZeneca vaccine. While daily cases numbers are still worryingly high in the UK, running around 40,000 a day, deaths have become relatively rare at just 10 per cent of the country's worst figures.

One EU country after another is going back into lockdown in the latest battle against Covid, with the continent on red alert as the bitter winter weather starts to bite (pictured, Lipizzaner horses go to training in Austria without any spectators as the country re-enters lockdown) Professor Bryan Williams, the emeritus director of the Melbourne-based Hudson Institute, also told Daily Mail Australia that there were more vaccines currently in testing which could potentially deal with any new strains such as Omicron. More than 4,000 are dying every day across Europe at the moment with Russia, Germany, Romania, Poland, Austria and the Netherlands among the worst hit.ĭaily cases numbers are frequently running at double the previous peaks from earlier in the pandemic - and are still rising, with more than 310,000 cases a day.īut UK deaths and case numbers have remained relatively constant since July, and experts believe the AstraZeneca jab may be playing a key part in that. One EU country after another is going back into lockdown in the latest battle against Covid, with the continent on red alert as the bitter winter weather starts to bite. The much-maligned AstraZeneca vaccine could prove key to Australia dodging yet another Covid wave sweeping the nation if the UK's experience is any guide.
