AstraZeneca says coronavirus vaccine candidate should be effective against new stress in UK

AstraZeneca chief executive Pascal Soryote said on Sunday that the British pharmaceutical company’s vaccine is being considered effective against the new coronavirus virus found in the UK

“By now, we think the vaccine should remain effective. But we are not sure, so we are going to test it, ”said Soriot when asked how the vaccine might hold up against the new type of virus.

The Associated Press reports Soriot told the Sunday Times that AstraZeneca researchers had discovered a “victory formula” to make their formula as effective as Pfizer or Morden, both of which have already been approved. The AstraZeneca vaccine is expected to be approved this week, AP notes.

“We think we’ve figured out the winning formula and how to get the efficacy, after two doses, with everyone there,” Sorot said.

AstraZeneca’s vaccine, developed in partnership with Austrian University, was not initially considered as effective as its American counterparts, with partial results suggesting it is 70 percent effective in preventing the disease, the AP report reported.

This new strain of the virus has removed the alarm worldwide, with many countries limiting or restricting travel to and from the UK, which is believed to be significantly more contagious than the already existing coronavirus virus, although it is more Not considered fatal or causal. More severe symptoms.

Modern said that last week it was also believed that its vaccine could effectively protect people from new strains.

An important difference in AstraZeneca vaccines is that, unlike Modern K and Pfizer vaccines, it is not an mRNA vaccine. According to the Centers for Disease Control and Prevention, these vaccines teach the immune system how to make certain proteins that trigger an immune response without the inclusion of real viruses in the body..

AstraZeneca’s vaccine uses a weaker version of the virus to teach the immune system how to shut it down.

The UK was the first Western country to approve a coronovirus vaccine, approving Pfizer’s vaccine in early December. As of 24 December, more than 600,000 vaccinations have been done in the UK, the AP reports.
