A coronavirus vaccine has proven to be 100% effective in youngsters aged 12 to 15, according to the manufacturers, writes Euronews.

Phase 3 trials involving 2,260 children in the United States “demonstrated 100% efficacy and robust antibody responses”, - Pfizer/BioNTech said in a statement.

They said they hope to begin vaccinating this age group before the next school year, and will seek authorisation from the US Food and Drug Administration and the European Medicines Agency to expand the use of the vaccine.

Currently the vaccine only has emergency use approval for those over the age of 16.

The vaccine “demonstrated 100% efficacy and robust antibody responses, exceeding those reported in trial of vaccinated 16-25 year old participants in an earlier analysis, and was well tolerated”, - the statement continued.
