People aged 40 to 44 will be able to register online for a Covid-19 vaccine on Wednesday.
44-year-olds can register on Wednesday June 2nd and the portal will open to those a year younger on each subsequent day, with 40-year-olds on Sunday.
The HSE’s Chief Clinical Officer expects the majority of that age group will be vaccinated by the end of June or early July.
Dr Colm Henry says the take up of vaccines to date has been the envy of Europe.
