The United States authorities closely follow the progress of the pandemic in their territory and constantly evaluate the effects that vaccination is having on the population. During this follow-up, it was found that unvaccinated people have a greater chance of presenting a serious disease and dying, as other studies have confirmed.

In the study, the CDC examined the effectiveness of vaccines against the most severe consequences of the disease. For reasons that are not entirely clear, data from one of the studies suggest that Moderna’s vaccine offered a slightly higher level of protection in the period where the delta variant was prevalent.

The study comes a day after President Joe Biden announced a strong new immunization plan that includes requirements for companies to employ more than 100 workers to be vaccinated or tested weekly.

The first study examined hundreds of thousands of cases in 13 United States jurisdictions between April 9 and June 19, before delta was dominant, and compared them with data collected between June 20 and July 17. From one period to the next, risk of people vaccinated from being infected with covid increased slightly: they went from being 11.1 times less likely to be infected compared to those not vaccinated, to 4.6 times less.

Protection against the risk of hospitalization and death remained more stable but fell more among those over 65 years concerning the younger groups.

The CDC and the Food and Drug Administration (FDA) are evaluating the need for booster vaccines, and older people are likely to be among the first to receive them when the Biden administration begins distributing them later this month.

One of the studies, which evaluated the effectiveness of the vaccine between June and August in more than 400 hospitals, emergency departments, and urgent care clinics, examined the effectiveness of each laboratory.

Moderna’s vaccine was most effective against hospitalization with 95%, then Pfizer with 80%, and finally Johnson & Johnson with 60%.

The CDC also warned in recent days that daily deaths from coronavirus increased in the country by 131% in the last month. At the moment, more than 640,000 people have died in the United States from the pandemic.

The delta variant is already the main responsible for the new hospital admissions, with 89,916 patients on September 2, figures that had not been seen since January 30 when 89,657 people had to be hospitalized. In some states, such as Georgia, Kentucky, and Hawaii, there are no clearances in intensive care units.

The CDC has also reported an increase in income for children and adolescents. The main person in charge of the fight against the coronavirus in the United States, Anthony Fauci, points out that there is still no data to determine that this variant occurs more aggressively among minors, who can access the Pfizer vaccine for 12 years.
