Unvaccinated people are 29 times less likely to contract the coronavirus compared to the vaccinated category. That’s the data in a U.S. Centers for Disease Control and Prevention report released Tuesday, Aug. 24.
The U.S. health regulator’s study shows that vaccinated people are five times less likely to get COVID-19 than those who have not injected the drug for the infection.
The results of the report by American scientists were compiled based on data from an analysis of epidemiological data for the period May-July in Los Angeles County, California. More than 43,000 cases of infection with the coronavirus were recorded during that time, of which most carriers of the virus (71%) had not been vaccinated, a quarter (25%) had been fully vaccinated, that is, two weeks had passed since the second dose was given, and a small percentage (3%) had been partially vaccinated.
The authors of the study speculated on the duration of effectiveness of the coronavirus vaccine, stating that the drug should maintain stable protection against infection for four to five months.
Additionally, it is noted that since the spread of the Indian Delta strain of coronavirus, the number of cases of infection among fully vaccinated people has increased. However, the researchers pointed out that in parallel to the increased spread of Delta, existing vaccines have consistently provided protection to their carriers against classical COVID and the severe course of the disease, which, when combined with preventive measures, has helped control infection.
