* Pfizer submits data from trials in 12- to 15-year olds
* EU also reviewing shot for same group
* Canada, US have started vaccinating children with Pfizer shot

Pfizer is seeking British approval for the use of its Covid-19 vaccine among 12- to 15-year olds and has submitted data to the health regulator, a company representative said on Tuesday, paving the way for inoculation of adolescents in the country.
The vaccine, developed along with Germany's BioNTech , has already been approved in the United States and Canada for use against Covid-19 infections in children and young adults.
"I can confirm we've submitted data on the efficacy of the vaccine in 12 to 15 year olds for review by UK MHRA," an official for the US drugmaker told Reuters, referring to the Medicines and Healthcare products Regulatory Agency.
Health officials are banking on vaccines to end the pandemic, but are worried that some parents will be hesitant in vaccinating their children due to fears of potential side effects and long-term risks. Kids under 12 have so far been less susceptible to Covid-19.
The drugmakers have said their shot is safe, effective and produced robust antibody responses in children as young as 12 years of age.
The vaccine, which uses mRNA technology to deliver instructions to the human body to build immunity against the illness, is also being tested in children aged two to 11, with safety and efficacy data expected in September, Pfizer has said.
Although other drugmakers, including AstraZeneca, Moderna and Johnson & Johnson , are working on vaccines for children, Pfizer and BioNTech have managed to steal a march.
Pfizer's vaccine, branded Comirnaty, is also under an EU review for use in children aged 12 to 15 years, with the head of the region's medicines regulator saying an approval could come as early as end-May.
The Telegraph earlier reported on the British review, saying the vaccine was likely to be approved before the end of July.
The MHRA did not immediately respond to a Reuters request for comment.
