The manufacturer of the coronavirus vaccine, Pfizer, claimed 100% effectiveness for children aged 12 to 15 years.
Such results were obtained during the third stage of clinical trials, reports CNBC.
The study involved 2,260 Americans.
Pfizer said there were 18 confirmed cases of COVID-19 in the placebo group and no confirmed infections in the vaccine-treated group.
It turned out that children tolerate the vaccine well, and the side effects generally correspond to those observed in adults.
Vaccinating children is critical to ending the pandemic, according to health officials and infectious disease experts.
Earlier it was reported that BioNTech united 13 pharmaceutical companies in an alliance for the production of the drug to provide them with the European Union and the rest of the world.
