WATCH: The COVID-19 vaccine Pfizer produced with BioNTech is 100 per cent effective in children aged 12 to 15, according to a press release from the pharmaceutical giant. As Eric Sorensen explains, while no shot has been approved for use for this age bracket yet, the preliminary results of the clinical trial are raising hopes for the future. – Mar 31, 2021

Pfizer Inc and BioNTech SE said on Wednesday their COVID-19 vaccine was safe and effective and produced robust antibody responses in 12- to 15-year olds, paving the way for them to seek U.S. emergency use authorization in weeks.

Pfizer hopes that vaccinations of the group could begin before the next school year, Albert Bourla, Pfizer’s chairman and chief executive, said in a statement.

Pfizer’s vaccine is already authorized for use in people starting at age 16. The new study offers the first evidence of how the vaccine will also work in school-age adolescents.

In the trial of 2,260 adolescents aged 12 to 15, there were 18 cases of COVID-19 in the group that got a placebo shot and none in the group that got the vaccine, resulting in 100 per cent efficacy in preventing COVID-19, the companies said in a statement.

The vaccine was well tolerated, with side effects in line with those seen among those aged 16 to 25 in the adult trial. It did not list the side effects for the younger group, but the adult trial’s side effects generally were mild to moderate and included injection-site pain, headaches, fever and fatigue.

The companies also studied a subset of teens to measure the level of virus-neutralizing antibodies a month after the second dose and found it was comparable to study participants aged 16 to 25 in the pivotal trial in adults.

Bourla said the company planned to seek emergency authorization from the U.S. Food and Drug Administration “in the coming weeks and to other regulators around the world, with the hope of starting to vaccinate this age group before the start of the next school year.”

Last week, the companies gave the first vaccine doses in a series of trials testing the vaccine in younger children, that will eventually go to those as young as six months of age.

Pfizer isn’t the only company seeking to lower the age limit for its vaccine. Results also are expected soon from a U.S. study of Moderna’s vaccine in 12- to 17-year-olds.

AstraZeneca last month began a study of its vaccine among 6- to 17-year-olds in Britain. Johnson & Johnson is planning its own pediatric studies. And in China, Sinovac recently announced it has submitted preliminary data to Chinese regulators showing its vaccine is safe in children as young as 3.
