The Pfizer/BioNTech COVID-19 vaccine offered less protection against the omicron variant than the delta strain in children, but protected against severe disease from both variants, according to a study published in the New England Journal of Medicine on Wednesday.

The report stated that vaccinating children aged 5 to 11 reduced hospitalizations with COVID-19 by more than two-thirds during the omicron surge and protected against serious illness.

Researchers found that vaccination also reduced hospitalizations associated with COVID-19 in adolescents aged 12 to 18 and strongly protected against serious illness, according to the study co-led by Dr. Adrienne Randolph, MD, M.Sc, at Boston Children’s Hospital with the Centers for Disease Control and Prevention.

According to the study, two doses of the Pfizer-BioNTech vaccine were 68% effective in preventing hospitalization for omicron in the group of children aged 5 to 11 years.

The study authors also said that in the 12-18 age group, vaccination was 92% effective against hospitalization with the delta variant, while it fell to 40% against the omicron variant. Despite the decline, the study authors said the vaccination was 96% effective in preventing severe cases of the disease during the delta period and 79% during the omicron wave.
