Coronavirus Vaccines Prevent Severe Infection Caused by Delta

• 

The US health authorities have confirmed that receiving full vaccine doses decreases the death risk of the Coronavirus by eleven times, and the probability of transferring the infected to the hospital by ten times.

Three new studies published by the Centers for Disease Control and Prevention in the US on Friday confirmed the effectiveness of Coronavirus vaccines in preventing severe virus complications.

For unknown reasons, the data indicates that the Moderna vaccine provided a higher degree of protection against the Delta variant. 

This comes after US President Joe Biden announced a strict vaccination plan that includes obliging companies that employ more than a hundred people to either vaccinate employees or subject them to weekly tests.

Rochelle Walensky, Director of the Centers for Disease Control and Prevention, reassured reporters that all studies are showing the effectiveness of the vaccines against Coronavirus.

Along with the Food and Drug Administration, the Centers for Disease Control and Prevention is evaluating the need for booster doses, and it is likely that the elderly will be the first to receive them.

A study that took place from June through August in more than 400 hospitals, emergency departments, and urgent care clinics, ranked the effectiveness of vaccines by brand against the need for hospitals.

With 95 percent, Moderna ranked first, followed by Pfizer (80 percent), and finally Johnson & Johnson (60 percent).

The overall effectiveness of preventing the need for hospitals was 86 percent for all age groups. However, the efficacy dropped to 76 percent among adults who are 75 years old and above.
