Pfizer-BioNTech Say COVID-19 Booster Protects Kids 5-11 Against Omicron

U.S. pharmaceutical company Pfizer and its German COVID-19 vaccine partner, BioNTech, announced Thursday recent trials show booster doses of its vaccine effectively protect healthy children ages 5 to 11 from the omicron variant of the coronavirus.

In a press release, the companies say their phase-three trials examined data from 140 children ages 5 through 11 who received a booster dose approximately 6 months after the initial two-dose Pfizer-BioNTech COVID-19 vaccine regimen.

The companies report, while all participants demonstrated significant increased protection, 30 of the trial participants showed omicron-neutralizing antibodies increased by 36 times compared to those who only received the original two-shot dosage.

The companies say more than 10,000 children under the age of 12 have participated in clinical trials investigating the Pfizer-BioNTech COVID-19 vaccine with no new safety concerns observed.

The studies have not been published or reviewed by independent scientists.

The companies plan to apply for U.S. Emergency Use Authorization of a booster dose in the 5-11 age group in coming days, with additional submissions to global regulatory agencies, including the European Medicines Agency, to follow.

Earlier this year, the U.S. Food and Drug Administration authorized a third dose of the Pfizer-BioNTech vaccine for children ages 12 to 15 and those aged 5 through 11 who are immunocompromised. The FDA has also approved a second booster — or fourth shot overall — of the vaccine for people 50 and older.

Some information for this report came from The Associated Press and Reuters.
