It comes just a week after the portal opened to those aged over 18.

Minister for Health Stephen Donnelly has confirmed that the Covid-19 vaccine portal will open for those aged over 16 today. It comes just a week after the portal opened to everyone in the country aged over 18 to receive an mRNA vaccine. Taking to Twitter on Monday he wrote: "Registration for those age 16 and 17 for a COVID-19 vaccine appointment will start tomorrow, Tuesday. "It's important that we continue to get as many of our population vaccinated as soon as vaccines are available and following the safety advice of our experts." https://twitter.com/donnellystephen/status/1419726046220402692?s=21 To register online for a vaccine, you will need a mobile phone number, an email address, your PPS number and your Eircode. If you do not have these things, you are advised to call the Covid-19 helpline to register by phone instead.

It comes as cases have been rising rapidly in recent weeks due to the highly-transmissable Delta variant, with 87% of cases today in people under 45. The country's Deputy Chief Medical Officer, Dr Ronan Glynn, said on Monday: “87% of cases today are in those aged less than 45 years. “If you are awaiting your vaccine or are awaiting your second dose, continue to protect yourself by following public health advice.”
