Corona vaccine effective in preventing hospitalization and death

Washington DC: The COVID-19 vaccine is very effective in preventing hospitalization and death, even against highly contagious delta variants, according to a new study in the United States.

Based on a study that monitored more than 600,000 COVID-19 cases in 13 states from April to mid-July and had a surge in delta variants, the US Centers for Disease Control and Prevention was fully vaccinated against unvaccinated individuals. We have confirmed that it is 4.5 times more likely to be infected than other people. , 10 times more likely to be hospitalized and 11 times more likely to die.

At a White House briefing last week, CDC director Rochelle Walensky said, “Vaccination is working. We have the scientific tools needed to turn the corner of this pandemic. “.

She added that more than 90% of Americans hospitalized for COVID-19 have not been vaccinated.

However, in this study, vaccine resistance dropped from 91% in spring to 78% in June and July, resulting in “breakthrough” cases or infection with the virus despite being completely vaccinated. We also found that cases accounted for 14% and 16% of hospitalizations. Number of deaths in June and July.

The CDC published two other studies last Friday suggesting inadequate protection for older people even after vaccination. After examining COVID-19 hospitalization records in nine states during the summer, we found that the protection rate for people aged 75 and over was 76% compared to 89% for all other adults.

In addition, five veterans’ medical centers found that the protection rate for hospitalization was 80% for people aged 65 and over, compared to 95% for people aged 18 to 64.

U.S. health officials have reviewed the latest real-world data to determine if all Americans, or at least some Americans, need booster shots and how soon they should be given after the last dose. increase. Food and Drug Administration advisors will publicly discuss Pfizer’s application to provide booster doses next week.
