The Department of Health has been notified of 467 new coronavirus cases.

The number of people with the virus being treated in intensive care is down one to 38 while overall, there are 99 Covid-19 patients in Irish hospitals.

Amid the disruption caused by the cyber attack on the HSE's system, the number of cases may change due to future data validation.

Meanwhile, the Irish Nurses and Midwives Organisation has called for an urgent meeting with the HSE to discuss the implications for second dose vaccinations of healthcare workers.

It comes after the National Immunisation Advisory Committee highlighted yesterday that the number of very rare type of blood clots linked to second doses of the AstraZeneca vaccine is higher than previously understood.

INMO General Secretary Phil Ní Sheaghdha said her members have always supported the precautionary principle and if there are issues about receiving a second dose of AstraZeneca that need to be clarified then they want that done.

She said she wants to have up-to-date information about the matter to give to her members today.

About 150,000 healthcare workers have yet to receive the second dose of a Covid-19 vaccine that would provide them with full protection against the virus.

In the main, it is a second dose of the AstraZeneca vaccine they are due to receive.

However, the most recent letter from NIAC to Chief Medical Officer Dr Tony Holohan, which was published yesterday, highlighted new concerns that the risk of very rare blood clots with low blood platelets, previously linked to the AstraZeneca vaccine, is higher after a second dose of the vaccine than previously understood.

NIAC also referred to new evidence suggesting it is safe and effective for people who received a first dose of AstraZeneca to switch to the Pfizer or Moderna mRNA vaccines for their second dose.

It also said it is reviewing the gap between vaccine doses because of new studies showing first doses only provide 33% protection against the highly contagious new Indian variant of the virus, but that a second dose substantially boosts that protection.

Ms Ní Sheaghdha said many of her members are due to start receiving second doses of the AstraZeneca vaccine next week.

Tánaiste Leo Varadkar, meanwhile, has said that over 70% of the population will be vaccinated by the end of June and more than 60% of the adult population will be fully vaccinated by the end of July.

Speaking on RTÉ's Morning Ireland, Mr Varadkar said that 300,000 more people are protected by vaccination each week and vaccination success is underpinning the decisions to reopen society and business.

The Fine Gael leader also said no vaccination will be necessary to attend concerts or sporting event once these restrictions are lifted.

He said safety will be based on standard public health precautions and limiting numbers.

Minister for Tourism, Culture, Arts and Sport Catherine Martin is to seek Cabinet approval for a number of test entertainment and sports events.

It will include large and small gigs in many genres ranging from classical to electronic music, along with sports fixtures, at locations across the country during June and July.

Earlier, Mr Vararkdar said it will be most likely antigen testing that will be used around these pilot events.
