The delta variant of coronavirus does not cause more severe courses of covid-19 in children, according to initial findings.
A study by the U.S. Centers for Disease Control and Prevention (CDC) shows that the proportion of severe courses of disease in children is currently not significantly different from that in January, when the alpha variant of the coronavirus was prevalent in the United States. In addition, the data suggest high efficacy of vaccine protection in adolescents.
The rate of Corona-related hospitalizations among children and adolescents aged 17 years and younger had recently risen sharply again in the U.S., reaching 1.4 per 100,000 in mid-August. The researchers then compared about 3,100 hospital cases from January with 164 from the current delta wave and found little difference in the severity of the courses.

The proportion of patients who had to be transferred to an intensive care unit was 26.5 percent in January before the Delta variant appeared; now it is 23.3 percent. Before delta, 6.1 percent of the patients recorded needed ventilation; with delta, it was 9.8 percent. These differences are not statistically significant. However, more data are needed for more robust results, according to the researchers.
The study clearly demonstrates the efficacy of Corona vaccination even against the Delta variant in adolescents. In the USA, vaccination is available from the age of twelve. Between June 20 and July 31, of 68 adolescents hospitalized, 59 were unvaccinated, five were vaccinated once and four were vaccinated twice. Thus, unvaccinated adolescents are about ten times more likely to be hospitalized in the event of Corona infection than vaccinated adolescents.
