The study found that unvaccinated people were 4.5 times more likely to be infected with COVID, 10 times more likely to be hospitalized, and 11 times more likely to die.
A new US study published on Friday COVID-19 (New Coronavirus Infection) vaccination Even if the highly contagious delta mutants dominate the country, they remain highly effective against hospitalization and death.
One study followed more than 600,000 COVID-19 cases in 13 states from April to mid-July. According to the Centers for Disease Control and Prevention, the surge in deltas in early summer meant that unvaccinated people were 4.5 times more likely to be infected than fully vaccinated, more than 10 times more likely to be hospitalized, and 11 times more likely to die.
“Vaccination works,” CDC director Dr. Rochelle Warrensky said at a White House briefing Friday. “This is what matters. We have the scientific tools needed to turn the corner of this pandemic.”
However, as previous data have shown, protection against coronavirus infection is slightly delayed. It was 91% in spring, but 78% in June and July.
The so-called “breakthrough” cases of complete vaccination accounted for 14% of hospitalizations and 16% of deaths in June and July, about twice as many as earlier this year.
The increase in these percentages is not surprising. No one says the vaccine is perfect, and health experts warn that as more Americans get vaccinated, they will, of course, make up the majority of cases.
Walensky said Friday that more than 90% of people in US hospitals suffering from COVID-19 have not been vaccinated.
The CDC published two studies on Friday suggesting that protection for the elderly is weakening. A study of COVID-19 hospitalizations in nine states in the summer found that 76% of people aged 75 and over were protected, compared to 89% in all other adults. In addition, at five veterans’ medical centers, COVID-19 protection against hospitalization was 95% for ages 18-64, compared to 80% for ages 65 and older.
The changes seen over time may be due to weakened immunity in people who were first vaccinated months ago, because the vaccine is not very strong against Delta, or in many countries. It’s not clear if it’s because of abandoning masks and other precautions Delta has begun to spread.
However, US health officials will review this latest real-world data when deciding whether at least some Americans need a booster and how soon after the last dose. Next week, a Food and Drug Administration adviser will publicly discuss Pfizer’s application and offer a third shot.
