AstraZeneca says coronavirus vaccine candidates should be effective against new strains in the UK



AstraZeneca CEO Pascal Soriot said on Sunday that the British pharmaceutical company’s vaccine is believed to be effective against the new coronavirus strain found in the UK.

“So far, we think the vaccine should still be effective. But we are not sure, so we will test it.” When asked how this vaccine resists the mutation of this new virus, Soriot said.

The Associated Press reported that Soriot told the Sunday Times that AstraZeneca’s researchers had discovered a “success formula” that made its formula as effective as the approved Pfizer or Moderna. The Associated Press pointed out that the AstraZeneca vaccine is expected to be approved this week.

Soriot said: “We think we have figured out the magic weapon and how to get an effective dose. After two doses, everyone else can use it.”

The Associated Press reported that the vaccine developed by AstraZeneca and the University of Oxford was not as effective as similar products in the United States at first. Part of the results showed that the vaccine is 70% effective in preventing diseases.

This new strain of virus has aroused global alarm, and many countries restrict or prohibit travel from the UK. This mutant strain is considered to be more infectious than the existing coronavirus strain, although it is not considered fatal or lethal. More serious symptoms.

Moderna said last week that it also believes that its vaccine can effectively protect people from new strains.

One major difference of the AstraZeneca vaccine is that, unlike Moderna and Pfizer’s vaccines, it is not an mRNA vaccine. According to the Centers for Disease Control and Prevention, these vaccines tell the immune system how to create certain proteins and then trigger an immune response without introducing actual viruses into the body..

AstraZeneca’s vaccine uses a weakened virus itself to tell the immune system how to fight it.

The United Kingdom was the first Western country to approve a coronavirus vaccine and approved Pfizer’s vaccine approval in early December. The Associated Press reported that as of December 24, there have been more than 600,000 vaccinations in the UK.
