The executive director of the AstraZeneca PharmaceuticalPascal Soriot ensures that the laboratory has found the “winning formula” to make its vaccine against Covid-19 be as effective as Pfizer and BioNTech, at 95 percent, and Moderna, at 94 percent.
“We believe that we have found the winning formula to achieve an effectiveness that, after two doses, be as tall as all the others“Soriot explained to sunday time about the vaccine that his company develops together with the University of Oxford.
However, no further details were provided, pending publication of 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 percent effectiveness, while the other received half a dose, followed by a full dose a month later, 90 percent effective.
According sunday time, the Oxford vaccine and AstraZeneca –much cheaper and easier to keep that those of Moderna and Pfizer- will receive this week the approval of the British regulatory authority, so it is expected that start inoculating in the first days of January.
Soriot believes that his vaccine It “should be effective” with the new strains of the virus, but acknowledges that “they cannot be sure”, so additional tests will be needed and they are already working on new versions.
