AstraZeneca says it has found the “winning formula” for its vaccine

London.- The executive director of the AstraZeneca pharmaceutical company, Pascal Soriot, says that the laboratory has found the “winning formula” to make its vaccine against COVID-19 effective at the level produced by Pfizer / BioNTech, with 95 %, and Modern, with 94%.

“We believe we have found the winning formula to achieve an effectiveness that, after two doses, is as high as all the others,” Soriot told the Sunday Times about the doses his company develops in conjunction with the Oxford University.

However, Soriot did not want to offer further details, waiting to publish the results of new tests soon.

AstraZeneca and Oxford published in November the preliminary results of their clinical study in two groups: one received two full doses of the vaccine, with a result of 62% effectiveness, while the other received half a dose, followed by a full dose one month later, with an effectiveness of 90%.

According to the Sunday Times, the Oxford and AstraZeneca vaccine – much cheaper and easier to maintain than those at Moderna and Pfizer – will receive the approval of the British regulatory authority this week, so it is expected may begin to inoculate in early January.

Soriot believes his vaccine “should be effective” with the new virus strains, but acknowledges that “they can’t be safe,” so additional testing will be needed.

For their part, the pharmacy and the Oxford lab are already working on new versions of the vaccine in case they might need it.
