People may need to get a fourth dose of vaccine to protect themselves against Covid-19, Tánaiste Leo Varadkar has warned.

As the roll-out of boosters will be extended to the over-50s from tomorrow, Mr Varadkar told the Dáil today that evidence from Israel shows immunity wanes after a third dose and a fourth dose may yet be needed.
