They are 11 times more likely to die from covid-19 if they are not vaccinated, says CDC

Vaccines against covid-19 they remain highly effective against hospitalizations and death, even as the more contagious delta variant spreads rapidly in the United States, according to new studies.

One of the reports released Friday tracked more than 600,000 COVID-19 cases in 13 states from April to mid-July. As the delta variant spread in early summer, those who were not vaccinated were 4.5 times more likely to become infected than those who were fully vaccinated, 10 times more likely to be hospitalized and 11 times more likely to die, according to Centers for Disease Control and Prevention (CDC).

“Vaccination works,” CDC director Dr. Rochelle Walensky said at a briefing at the White House on Friday. “The bottom line is this: we have the scientific tools we need to turn this pandemic around.”

However, as previous data have shown, protection is declining: in the spring it was 91% and in June and July it was 78%, the study found.

Cases of infections in fully vaccinated people they accounted for 14% of hospitalizations and 16% of deaths in June and July, almost double than a few months ago.

This increase is not surprising: No one said vaccines were perfect, and health experts warned that as more Americans get vaccinated, they would account for a larger fraction of cases.

Walensky said on Friday that more than 90% of people hospitalized for COVID-19 in the country are not vaccinated.

The CDC released two other studies on Friday that indicate waning protection for older adults.

It is not clear whether the changes seen over time are due to declining immunity in people who were first vaccinated many months ago, because the vaccine is not as effective against the delta variant, or because much of the The country abandoned masks and other precautions just as the most contagious variant was beginning to spread, but health authorities will take this into account when deciding whether Americans need a booster vaccine and how soon after their last dose.

In the coming days, advisers to the Food and Drug Administration (FDA) will publicly discuss Pfizer’s request to offer a third dose.
