The manufacturers of the Pfizer BioNTech Covid-19 vaccine have submitted a request to the European Medicines Agency to expand the use of their vaccine to include adolescents aged 12 to 15.

There are four separate Covid-19 vaccines licensed for use here.

So far however, none are available for our 275,000 people aged between 12 and 15-years old.

Now, Pfizer BioNTech, who have supplied 72% of the vaccines so far administered in Ireland, are aiming to change that.

A phase-three clinical trial they conducted among 2,260 young people in that age group showed their vaccine to be 100% effective against the virus, that it produced robust antibody responses, and was well tolerated.

They have submitted their test data to the European Medicines Agency along with a formal request to extend the use of their vaccine to this age group throughout Europe.

If the application is successful, it would have significant and positive implications for our secondary school population.
