Pfizer Covid vaccine was just 12% effective against omicron in kids 5 to 11, study finds

Pfizer and BioNTech’s two-dose Covid vaccine provided very little protection for children aged 5 to 11 during the wave of omicron infection in New York, according to a study published Monday.

The New York State Department of Health found that the effectiveness of Pfizer’s vaccine against Covid infection plummeted from 68% to 12% for kids in that age group during the omicron surge from Dec. 13 through Jan 24. Protection against hospitalization dropped from 100% to 48% during the same period.

The study has not yet undergone peer review, the academic gold standard. Due to the public health urgency of the pandemic, scientists have been publishing the results of their studies before such review.

Today, the U.S. Food and Drug Administration authorized the emergency use of the Pfizer-BioNTech COVID-19 Vaccine for the prevention of COVID-19 to include children 5 through 11 years of age. The authorization was based on the FDA’s thorough and transparent evaluation of the data that included input from independent advisory committee experts who overwhelmingly voted in favor of making the vaccine available to children in this age group.
Key points for parents and caregivers:

Effectiveness: Immune responses of children 5 through 11 years of age were comparable to those of individuals 16 through 25 years of age. In addition, the vaccine was found to be 90.7% effective in preventing COVID-19 in children 5 through 11.
Safety: The vaccine’s safety was studied in approximately 3,100 children age 5 through 11 who received the vaccine and no serious side effects have been detected in the ongoing study.
The Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices will meet next week to discuss further clinical recommendations.
