Minister for Health Stephen Donnelly has said registration for a Covid-19 vaccine for children and teenagers, aged 12-15, will open next week.

In a tweet, the minister said: "I'm encouraging parents and these young people to seek information from reliable sources such as the HSE website."

The National Immunisation Advisory Committee recommended last month that all children aged 12 to 15 should be offered an mRNA vaccine.

The vaccines which will be offered are the Pfizer/BioNTech and Moderna vaccines.

Both of these vaccines have been approved by the European Medicines Agency as safe and effective.

During clinical trials, the estimate for efficacy of both vaccines was reported as 100% in these age groups.
