Researchers with the New York State Department of Health found that the vaccine's effectiveness dropped from 68% to 12% in children aged 5 through 11 between Dec. 13 through Jan. 24.
But the Centers for Disease Control and Prevention issued a report on Tuesday that stated the vaccine effectiveness in children between the ages of 5 and 11 after its second dose was 46%. "Two doses protect against COVID-19–associated emergency department and urgent care encounters among children and adolescents," the CDC report said."However, vaccine effectiveness was lower during omicron predominance and decreased with time since vaccination."
The public health officials who conducted the study believe it may be due to the lower dosage they received.The study also found that the effectiveness in children ages 12 to 17 dropped from 66% to 51%.Last week, the Centers for Disease Control and Prevention eased its masking guidelines.
