A few weeks ago, the entire British scientific community was outraged by the words of French President Emmanuel Macron, who probably unintentionally stated that the AstraZeneca vaccine in collaboration with the University of Oxford was "almost ineffective".
But a study by Scottish health authorities, based on more than 1 million vaccinations carried out from December to February 14, seems to not only refute the French president's joke, but also overturn the well-known data comparing it to vaccines. others.
According to the study, AstraZeneca has reduced by 94% the hospitalization of vaccinated people after the first dose, a statistic that exceeds the expectations of the vaccine makers themselves, and that exceeds the data of the most widely used vaccine so far, that of Pfizer. In more detail, out of more than 1 million vaccinated, only 8,000 have been sent to hospital. Statistics decrease somewhat when talking about patients over 80 years old, but still remain in 80% of cases.
The U.S. vaccine, according to study data, has had 84% reduction in supplements, although it has a greater immune defense, 95% after two doses. This is one of the first studies of the practical efficacy of vaccines, and represents excellent and promising news in the fight against the pandemic that has gripped the world since last year.
