American studies: full vaccination against corona reduces the risk of death from the virus 11 times


Three research papers published by the US Centers for Disease Control and Prevention (CDC) found that people who were fully vaccinated against the coronavirus were 11 times less likely to die and 10 times less likely to be hospitalized than unvaccinated people because the highly contagious delta variant became the most common variant.


According to a report by south china post, the data came from one of three new research papers published by the Centers for Disease Control and Prevention, all of which confirmed the ongoing effectiveness of corona vaccines against dangerous results.



"As we've shown in study after study, vaccination works against new dangerous variants," Rochelle Walnsky, director of the Centers for Disease Control and Prevention, said during a news conference.


The first study examined hundreds of thousands of people in 13 US jurisdictions from April 4 to June 19, the period before Delta's takeover, and compared it with June 20 - July 17.


Between these periods, the risk of a vaccinated person contracting MERS increased slightly from 11 times less likely than an unvaccinated person, to five times the risk of infection. Protection from hospitalization and death remained more stable, but decreased more significantly among people aged 65 and over. above compared to younger age groups.


The Centers for Disease Control and the Food and Drug Administration are evaluating the need for booster doses of corona vaccines, and it is likely that older adults.


One study that evaluated vaccine efficacy from June to August in more than 400 hospitals, emergency departments, and urgent care clinics revealed that the efficacy against hospitalization was highest in Moderna at 95%, then Pfizer at 80%, and finally Johnson's at 60%, the overall effectiveness against Hospitalization was 86 percent for all age groups, but this dropped to 76 percent for those over 75.
