Chair of NPHET's modelling group, Professor Philip Nolan and Professor Karina Butler, chair of the State’s vaccine body, NIAC, will also face questioning from TDs.
NPHET is expected to give an update on Covid-19 to the Health Committee, which consists of a mix of TDs in the Dail from different political parties.

Dr Holohan's contribution will be deemed significant as it will indicate as the Government prepares to press ahead with the relaxation of all restrictions on October 22.
