Unvaccinated people are 11 times more likely to die from Covid-19

One study tracked over 600,000 COVID-19 instances in thirteen states from April to mid-July. As delta surged in early summer, people who had been unvaccinated were four times more likely than the fully vaccinated to get infected, over 10 times much more likely to be hospitalized, and 11 times more likely to die, according to the Centers for Disease Control and Prevention.

"Vaccination works," Dr. Rochelle Walensky, CDC's director, told. "The bottom line is this: We have the medical gear we need to turn the corner on this pandemic."

But as prior data has shown, protection against coronavirus contamination is slipping some: It was 91% withinside the spring but 78% through June and July, the study indicated.

So-called "breakthrough" cases in the fully vaccinated accounted for 14% of hospitalizations and 16% of deaths in June and July are approximate twice the percentage as earlier in 2021.

Growth in those percentages isn't surprising: No one ever stated that the vaccines were perfect! Health experts have warned that as more Americans get vaccinated, they naturally will account for a greater fraction of the cases. Also in Veterans Affairs Medical Centers, protection against COVID-19 hospitalizations was 95% amongst 18- to 64-year-olds in comparison to 80% among those 65 and older.

It isn't clear if the changes seen over time are due to the fact that immunity is fading in people first vaccinated many months ago, that the vaccine isn't quite as strong against delta, or that most of the people aren’t following health protocols and choose not to wear a mask, and other precautions just as delta started spreading.

But U.S. health government will take brand new data into account as they decide if at least some Americans need a booster, and how soon after their ultimate dose. Next week, advisers to the Food and Drug Administration will publicly debate Pfizer's application to provide a third shot.
