The HSE failed to hit the Government's target of administering 100,000 vaccine doses last week due to AstraZeneca delivery delays.

According to the GP coordinating the community vaccination effort, the target of vaccinating all over-85s by the end of this week is also unlikely to be achieved.

With the Government apparently considering tighter restrictions on international travel, can our vaccine rollout stay ahead of the growing number of COVID-19 variants?

Kingston Mills, Professor of Experimental Immunology at Trinity College Dublin, and Dr Illona Duffy, a GP based in Monaghan, joined us to discuss these issues.
