A new study of the U-S Centers for Disease Control and Prevention show that people who have been vaccinated against coronavirus have milder COVID-19 illness than un-vaccinated people, if they become infected.
CDC said the study, which looked at more than 3,900 essential workers, shows fully vaccinated people are more than 90% protected against infection.
Even partially vaccinated people are 81% less likely to become infected than people who have not been inoculated, according to the ongoing study.
The CDC said in a statement that the result of the study adds to the growing body of real-world evidence of the effectiveness of the vaccines.
While the U-S sees COVID-19 vaccination rates growing among some populations, experts warn that lags among groups including adolescents could hurt a further return to normalcy.
Medical experts have warned that as more adults get vaccinated, the virus will continue to plague children who have not or cannot get inoculated yet.
In an interview by CNN, epidemiologist Dr. Abdul El-Sayed emphasized that more and more seniors, people with pre-existing conditions and people who may be healthy and younger were vaccinated.
Children are still considered much less likely than adults to develop severe symptoms of COVID-19 or to die from the disease.
Nevertheless, nearly a third of children ages 12 to 17 who were likely hospitalized primarily for COVID-19 in the first three months of 2021 were admitted to intensive care units and roughly 5% required invasive mechanical ventilation, according to a study by the U-S CDC that examined more than 200 adolescents. None died, the report added.
